My First Electric BMW

Recently I teamed up with the marketing guys at BMW of Bridgeport Connecticut to test drive my first electric BMW. I took out a 2018 i3 on loan, a car that I’ve wanted to test drive ever since I heard about its development in Leipzig, Germany.

Here’s a video I posted to my YouTube channel sharing a little bit about the experience.

My First Electric BMW

E90 BMW Broke Down with All Warning Lights On and The Car Won’t Drive

If you’re experiencing the classic dashboard lit up like a Christmas tree scenario in your E90 3-series BMW, you are probably thinking that something horribly catastrophic just happened to your car.

But don’t worry, yet.

Recently my 2007 335i broke down on the highway on the way home from my mother-in-law’s birthday celebration. I was with my wife and daughter and it was just getting dark out. It was also the hottest and most humid day of the year so far with temps around 90 degrees.

This was the worst possible time to experience a break down!

The car was cruising along for 15 minutes on the journey home, without any hint of a problem. All of a sudden, every warning light in the car came on and it began slowing down. The speedometer dropped to zero, even though we were going 65 MPH. The transmission shifting felt clunky, too.

The coolant, ABS, airbag, DSC dynamic stability control, brake, service engine soon, yellow gear of death, and others, came on and cycled through like a holiday light display. The car was jerky and then would not drive. Once I pulled over to a safe place, I turned the car off and back on. I tried to drive, but the shifter would not come out of park. I thought the car was in limp mode, but it really wasn’t.

Looking back on all of this now, it’s easy to see that this group of symptoms was a classic voltage regulator failure. When that part fails, the alternator overcharges the system with 18+ volts, when it should only be receiving in the 13.8 range.

As a result, all of the car’s complex modules and computer systems go haywire due to the extra voltage; if you continue limping the car along like this, a module or electronic part may get fried. So it is best to pull over and call for a tow.

Thankfully, I had AAA roadside service, which I highly recommend to anyone. I have the gold service for around $120 per year, which includes up to 100 miles of towing. That’s the one to get.

My mother in-law came to pick up my wife and daughter to take them home, and I waited with the car for AAA who arrived 15 minutes later. I can’t say enough good things about the AAA service. When you need it, you need it. Especially if you own several BMW cars.

I had to car towed to my house, though I was tempted to bring it to a local shop because I was so thrown off by the number of lights and codes. Upon scanning the car with my $60 C310 scan tool, I saw many codes for over-voltage. That is a clear sign that the voltage regulator needs inspection.

I ordered a Bosch unit from FCP Euro for around $43 and had it the same day. Typically, there is no need to replace the entire alternator, which is more like $400 and a ton of work. To replace the entire alternator, the oil filter housing must be removed in order to make room. I recommend trying the $43 part first, which can be installed in less than an hour with simple hand tools.

Old brushes on left, New brushes on right

Upon removing the old voltage regulator, I saw that the brushes were very worn down. You can see in the image above that the new brushes are more than twice the length of the old ones. These brushes wear down over the years and eventually fail; the alternator is designed that way and the regulator is designed to be easily removed and replaced.

The BMW part number for this regulator is 12317561939.

If you drive an E90 3-series, replace these brushes as soon as possible. It’s an easy job, less than $50 and just might save you from an unexpected break down.

Rescuing a Classic BMW E39 Touring Sport Wagon

It’s been nearly five months since I last posted a video on YouTube. It was a fun video where I just drove around in our E53 X5 during a blizzard here in Connecticut. That was early February, 2021. Check it out below:

It was around this time that I came across a very sad 525iT which was just listed for sale locally on Craigslist. With several feet of snow piling up during a tough New England winter, there wasn’t much to do but indulge in the pastime we all love: browsing online car ads for old BMW’s.

It wasn’t long before I saw the touring ad on Craigslist Fairfield. It had been advertised for $1,600 which seemed like a steal at first glance. That was of course, until I saw the car in person. It was definitely the worst condition car I’ve probably ever seen, let alone purchased.

Meeting with the Seller

Nearly everything was broken and needed replacing. Service engine soon light illuminated. Seats torn. Driver seat not moving. Interior disgusting. Rust. Dents. Dings. Sunroof stuck closed. Curb rash on every wheel. Valve cover gasket leaking. One hundred and ninety thousand miles on the clock. Recently failed emissions test. Missing side mirror and rear wiper arm. It also sported a mystery battery drain issue, which later turned out to be a bad DSP amp sucking juice from the battery overnight.

But somehow, none of that mattered. I had never seen an E39 touring wagon in person, nor had I owned one. Perhaps that’s a testament to how rare they really are; only around 5,000 525i Touring cars were imported to the US.

As a staunch E39 enthusiast, I was really excited at the prospect of owning a touring, without spending $10,000 for a nice one. You may be shocked at how much they’re selling for on Bring a Trailer these days. Check out the market today, here.

540iT Sold for $27,500 March 9, 2021

I did decode the VIN number with a BMW VIN decoder to see what options it had, which were unique. Xenon lights, self-leveling sport suspension, DSP premium sound system, rear sun blinds, sport premium package, convenience package. A clean CarFax report revealed only two owners and no accident history. It also had a clean Connecticut title.

Upon inspecting the car, a box in the trunk offered a glimmer of hope. Inside it revealed a 3” thick binder of BMW dealer service history since 2001 along with the original window sticker. There’s always something inspiring about finding the original window sticker and service records. Next to that were the monster two-volume E39 Bentley manuals. The service history was exclusively performed at BMW dealerships which added up to over $20,000 invested since 2001.

Recent work for big-ticket items included: new rear air suspension springs, new front struts, oil pan gasket, and a $750 BMW windshield replacement done at BMW. The original owner really loved this car.

The 525iT’s Original Window Sticker

I then did something I had never done before. I told the seller I would consider it and get back to them. Usually, I come prepared to jump on a car deal right away, which one should always prepared to do. But this time, I really didn’t want a project of this magnitude. So I waited two days. I really didn’t want it. Honest. But someone had to rescue it. After all, this was the police car used by the Berlin Polizei in Germany from 2001-2004. More on that later.

I floated an offer of $900 to the seller, which they immediately accepted. They wanted to see it get rebuilt on YouTube, and they knew it was going into the right hands if I bought it.

Blizzard Begins as the Touring arrived home

I was supposed to be done rescuing old BMW’s. Yet here we were, with a tiny suburban driveway full of future projects and a blizzard ready to drop several feet of snow.

As we enter the July 4th weekend of Summer 2021, I am finally beginning to edit YouTube videos again. I’ve been filming every detail of every repair on this Touring rescue over the last five months. Nights, weekends, and sometimes during the day, only if I’m blessed with a long enough baby nap.

As a full-time stay-at-home Dad, my channel has been on the back burner this year. I look forward to bringing you this E39 Touring rescue series in the coming weeks on YouTube. Thanks for sticking around.

Test Driving a 2021 Tesla at the Milford, Connecticut Gallery

About a month ago I made a video called The End of Gas Powered BMW’s where I drove around in my 1990 735iL just talking to the camera about electric cars and my desire to drive one. I’ve been curious and interested in electric vehicles for a long time. In fact, I gave an elaborate presentation on Toyota’s hybrid technology for an engineering class at The University of Connecticut back in 2006. Wow, it’s hard to believe my college days were that long ago.

Anyway, after uploading that video, it turns out that one of my subscribers is a Tesla employee who also happens to be a BMW enthusiast. Hey, even Elon Musk began his passion for cars with BMW, long before the idea for Tesla was born. Elon’s mother tweeted the photo below two years ago: Elon working on his E21 BMW in 1995!

Elon’s E21 BMW in 1995

In the photo, it looks like he has the door card trim panel removed to repair a broken window regulator motor. The steering wheel also appears to be a three spoke sport 320iS wheel, so Elon had good taste in well-engineered cars even then.

Allen, the Tesla employee and viewer, emailed me with an offer to come down to the Milford, Connecticut Tesla Gallery to test drive the new 2021 Model 3 and 2021 Model Y. Of course I jumped at this opportunity as soon as I could get down there to drive cars for a few hours.

Upon arriving, we introduced ourselves from a safe, social distance while wearing face masks of course. While chatting about his BMW experiences, Allen performed Tesla’s safety protocol for test-drive-prep: wiping down all surfaces, steering wheel, door panels and touch points with disinfectant and a microfiber towel. The windows are also down to allow fresh air to blow through the car. Test driving a car can be challenging during a pandemic, but Tesla seems to have a very strict (and safe) procedure in place.

You can even schedule a contactless test drive on Tesla’s website, here. This is so far removed from the olden days where a pushy salesman would ride in the passenger seat with you on the test drive, digging for your financial info. Tesla is doing it right; enjoy and experience the product on your own accord, with space, no pressure at all. The gallery experience is akin to a trip to the Apple store, where the entire experience is considered carefully. Bravo, Elon.

Test Driving the 2021 Tesla Model 3 Plus (Base Model)

Before the test drive, your sales associate will hand you a plastic Tesla credit card which acts as your key. It holds a chip that activates the car by placing it down on the center console behind the cupholder space. A chime from the car lets you know the car is now on. From a safe distance, Allen described to me how to adjust the mirrors, steering wheel, seat and the available steering options. I could drive around as I pleased, or set the navigation to their predetermined route called Work.

Selecting Work would bring you around the twisty backroads of Milford, and then up onto the Merritt Parkway rt. 15 for a jaunt at speed on the highway. Selecting Home on the navigation touch screen would automatically direct you back to the dealership. Genius.

What was most noticeable upon entering the model 3 was the shape of the steering wheel. The wheel diameter was round, of course, but the shape of the steering wheel handle radius had a square oblong shape to it, not round like a standard steering wheel. Interesting. This shape must somehow enhance your grip on the controls as the instant torque of the dual motors forces your body deep into the vegan leather seats.

The next thing immediately noticeable was how the regenerative breaking grabs you and slows down the car – as if you were hitting the brakes – as soon as you lift off the “go pedal”. With enough practice, Tesla drivers can operate the car with what is known as one pedal driving: effectively accelerating and slowing down with just one pedal.

Overall, the model 3 was a pleasure to drive, quiet, with a build quality that was high and a drive as sporty as a 3 series BMW. The base model lacked a bit of wow factor that I was hoping for, but I quickly found that special quality as soon as I got into the 2021 Model Y Performance model.

Driving the 2021 Tesla Model Y Dual Motor AWD Performance Model

The Model Y is the newly released mid size SUV offering from Tesla, but critics have called it merely a bloated model 3. The car doesn’t look too big from the outside, but once you get in, it feels spacious like a mid sized SUV. The ride height and visibility through the front glass felt very similar to our first generation 2005 E53 X5 BMW that my wife daily drives to work. Though I lament the level of maintenance it has required over the past five years, the X5 has grown on me lately, and I may hold onto it for an X5 overland build coming soon. More on that later.

The performance model Y comes in at around $60,000 USD which is a substantial amount of money for this market segment. However, there are not many SUV’s (read: none) that are all electric, dual motor, and can do 0-60 in as little as 3.5 seconds. The performance of this SUV is just absurd, so much fun, constant acceleration with no delay between gears to shift.

I fell in love with the Model Y instantly, it is everything I would want in a new family hauler. The 326 mile range and supercharging is more than enough to suit our personal transportation needs.

As a life long BMW enthusiast, I am really looking forward to seeing the new i4 electric sedan and iX electric SUV offering from BMW. The i3 is another car I’m looking forward to driving on the channel soon, though I doubt it would be a practical dad car due to the rear door design and small overall size. We will see how that goes.

Thanks for reading, supporting this blog, and watching the videos.

Happy New Year

BMW Ownership: A Decision Made in the Spirit

Last week I came across an interesting document while browsing vintage BMW literature online. The document is a 1989 Preview Brochure for the 3er, 5er and 7er series BMW cars. In my 17 years of BMW ownership, I had never even heard of a preview brochure. I was shocked at how well the introduction was written; it really sums up our collective enthusiasm for BMW car culture in an eloquent and simple way.

We have to appreciate how this kind of marketing material could only have come from a boutique, West German auto manufacturer in 1989, just months before the Berlin Wall fell.

Back then, the company was not the corporate behemoth that it is today. One can recognize where the copy must have been loosely translated directly from German, as the wording has a kink or two. Today, that marketing copy would be so highly polished by the BMW executives that something like this would never see the light of day in the US market.

Here’s what it means to be a BMW enthusiast. The next time someone asks you why you love the car so much, simply reply with the following prose:

There are probably more rational reasons for driving a BMW than exist for any other automobile in the world.

Yet it is a fact that many BMW drivers have a passion for these cars that makes them understand them, experience them, at a different level. Certainly, reason plays a part in this understanding. But to some, their appreciation of these automobiles is more arcane, as if they were experienced through the skin.

In such cases there becomes an attachment between the individual and the machine taken beyond the usual, where there is found a conjoining of spirit, of personality of essence. With a tacit understanding that the challenges are made and met, not between man and machine but man and himself.

Many will find such views romantic. But not all. Some are drawn to such automobiles, not as an act of will but as a decision made in the spirit.

To drive such an automobile is entirely satisfying. For a brief period, it denies time.

One’s attachment to humanity is put on hold. Man and machine become one.

It is the Ultimate Driving Experience.

Making Money on YouTube with a BMW Car Related Niche Channel in 2020

Five years ago I began uploading videos to YouTube, primarily as an experiment to see how things worked. When unique problems or issues came up on my cars, I thought I could turn that problem into an opportunity. The opportunity was a chance to share my experience and help others facing the same issues, as most BMW issues are commonly shared between models. When something broke, and break they did, I thought to myself: “Great, here’s another video.”

The other opportunity that often comes with solving other people’s problems, is money. In this case, for me, it’s not much (yet). But I do earn a small income from the BMW video content I produce and upload to my YouTube channel. This topic is somewhat taboo as many creators choose not to share how they’re doing on the financial side of things. I think that a secretive mindset is a huge disservice; sharing the knowledge one has simply expands opportunities for others and takes nothing away from those who share it.

Everyone with an interest in creating on this platform could benefit from a little help and behind-the-scenes look at earning money to see if it is something that could be viable for them. The truth is, unless you’re really talented and full of energy to create, it can be difficult to earn a full time living from uploading niche YouTube videos. But that doesn’t mean that you shouldn’t try.

In this video below, I discuss how much some of my recent videos have earned and the various ways which you can monetize a YouTube channel in 2020 and beyond.

Are you interested in starting a YouTube channel of your own? Let me know in the comment section on this video and I’ll reply to your ideas, or check out your channel if you’ve already started one.

With the COVID pandemic keeping millions of people around the world stuck at home, starting a YouTube channel in 2020 is a great way to creatively express yourself and share something with the world from a safe distance. You never know, your experimental channel could just become a new career for you.

Five New YouTube Videos on my 1990 E32 735iL

Recently, upon late night browsing of Facebook Marketplace, I stumbled upon a 1990 735iL available for sale. Days went by, then a week. I saw that the car was still available and it was on my mind; I couldn’t stop thinking about how great the car’s condition was. It had been garage kept and driven less than 1,000 miles per year since 2008.

Then, Facebook’s sneaky notification buzzed my iPhone. The asking price had dropped from $3,500 USD down to $2,900 USD. I asked for some details on the car, checked out the VIN number, and prepared my offer. I asked if $2,500 USD would do. It was accepted. One week later on a Sunday afternoon the seller delivered the car to my driveway two hours from New York!

This Fall 2020 E32 project began as an accidental purchase of a classic BMW that I really should not have purchased. My day job is a stay-at-home Dad to my one year old daughter. I run a business and YouTube channel on nights and weekends, which leaves little time to maintain the three BMW’s we already own. This new arrival makes four. My wife is a patient and understanding gem.

To be fair though, the acquisition of new and interesting cars is what fuels this blog and YouTube channel to begin with. I like to think about it this way: even once the car is eventually sold on, I get to keep the videos and memories forever. Of course, I hope the content continues to bring in royalties in perpetuity, too.

To keep this BMW classic blog updated and interesting, here are the first five new videos I made about the new purchase. I’m slowly replacing and repairing the little items that are often overlooked, along with some basic maintenance and servicing. Enjoy.

I Bought a 1990 Islandgrun E32 735iL BMW

This first video is really just to show off how cool this E32 735iL really is. It has some rare options including its color: islandgrun metallic. This long wheelbase 7er has 4.5” of extra leg room in the rear, along with a power adjustable rear seat and an uber rare LSD – limited slip differential.

What Special Coolant Does My BMW Take?

The idea for this video came when I realized how often I’m asked about coolant in these cars. BMW basics is a series of videos where I try to appreciate what seems obvious to a seasoned enthusiast may not be obvious to everyone. This is one of those things. In this video I share why it’s important to use BMW blue coolant in your car, not the garden variety green stuff.

How to Perform The BMW Stomp Code Test Procedure

The BMW Stomp Test as it’s known as, was a fun rediscovery of an old trick. This trick allows you to read and decipher OBDI diagnostic trouble codes on 1995 and earlier BMW cars. For many years I shared a 1994 530i 5-speed sedan with my Dad, the last car of this era with the stomp test feature. Since the car was sold in 2014, I’ve only driven BMW’s with OBDII diagnostic capabilities, so this feature was long since forgotten. Until I bought the E32.

BMW Door Handle Gasket Rubber Seal Removal and Replacement

Another element the E32 shares with the E34 is the door handle gasket issue. These cars have rubber gaskets surrounding the door handles which dry out over time, crack and rot. They’re unsightly and can allow water into the door. I can’t recall ever replacing them on my Dad’s old E34, but I got to try it for the first time on the new 735iL.

BMW Broken Fuel Gas Door Hinge Repair

Finally, the good old broken fuel hinge issue: I’ve definitely been here before. My Dad’s E34 had this same problem, so when I saw that the fuel door wouldn’t stay open, I knew what needed to be done. This is where experience saves the day. The hairline crack in the hinge is not easily visible, but can be seen if the door is overextended outwards. The repair is relatively difficult, because of the design of the plastic hinge.

So there you go, five new YouTube videos on the Bimmerzeit channel. More to come, soon. As Gary Vaynerchuk says, content is king.


BMW Intermittent Random Stalling Issue Help

If your BMW is randomly stalling out, it is dangerous to your safety on the road, and it must be resolved ASAP. Here are some of the common reasons why your BMW might be exhibiting stalling issues.

  1. The fuel pump is faulty and needs to be replaced.

2. The crank position sensor is faulty and needs to be replaced. This is common on older classic cars such as the E30, E32, E34 and E36. But it can also present as an issue on modern cars like the E39, E46.

3. One of the most difficult to diagnose stalling issues is when the intake camshaft position sensor is beginning to fail. This part will fail very slowly overtime, and will not always throw a service engine light with stored code. This makes diagnosis next to impossible. This stalling happens in slow speed such as coming to a stop sign or slow drives around a shopping center parking lot, for example.

If your BMW is showing these symptoms of intermittent stalling, with no trouble codes present, it might be the intake camshaft position sensor. If you’re lucky, you’ll eventually see the P0340 generic trouble code appear on your BMW scan tool. That will confirm the intake camshaft position sensor has failed.

BMW Door Handle Gasket Seal Replacement E31, E32, E34, E36

The rubber door handle gaskets on the E31 8 series, E32 7 series, E34 5 series and E36 3 series cars will all fail in time. The original BMW gasket dries up in the sun from UV exposure over the years causing cracking and crumbling. Unfortunately BMW does not sell the gaskets separately, so you must purchase the entire door handle if going with the genuine replacement. This can add up to several hundred dollars for a sedan.

Before / After

Instead, quality aftermarket gasket kits are what most people use, coming in at around $29 USD for a set of four gaskets. You can buy a set here.

How to Remove the Door Handle Cover Plate and Gasket

  1. Open the door and look at the jam on the edge of the door
  2. With a nylon pry tool, remove the plastic cap covering the access hole. Avoid using a metal object for this step as it can damage your paint.
  3. Spray lubricant such as WD40 onto the sliding brass mechanism and allow to sit for a few minutes. This step makes the job substantially easier.
  4. Push the brass slider in the access hole in towards the car’s interior
  5. This will allow the outer door handle trim and gasket to pop off
  6. Clean the door handle area thoroughly of dirt, grease and debris
  7. Install the new rubber gasket to the door trim plate
  8. Place the gasket with trim plate back onto the door. While holding it firmly against the door with one hand, use a hook tool like this one to pull the brass slider back out towards yourself (away from the car).
  9. Replace access hole plastic cover
  10. You’re done! Move onto the next door.

How to Do The BMW Trouble Code Stomp Test for E30, E31, E32, E34, E36 Cars

You may have heard about the “Stomp Test” that can tell you what trouble codes are stored in your vintage BMW’s engine computer. Unlike modern OBD II cars (from 1995 onward) that use a scan tool plugged into the OBD II port, older cars system is classified as OBD I. Some cars have this OBD I diagnostic port under the hood which can allow for a tool to scan for codes.

Fortunately for classic BMW drivers in the US, there is the Stomp Test. This works on cars with Bosch Motronic 1.3 or later, which is in model year 1988 cars and up. If you have a 1987 model year BMW, it may be on the cusp, so it depends on what ECU is in the car and its production date. I have been told this test does not work on European or Euro Spec cars, though have not confirmed myself.

How To perform the Stomp Test:

  1. Turn the ignition to position two. That’s the second click on turning the key. Do not start the car.
  2. Press the gas pedal to the floor five times within 5 or 6 seconds.
  3. After one flash of the check engine light, the process will begin.
  4. Engine light will flash a four digit code using morse code to communicate the trouble code, if one exists.
  5. It is helpful to keep a pen and pad to note the numbers displayed.
  6. Refer to the list of trouble codes here to begin diagnosis
