How to Replace Program and Register a new BMW Battery

If you’re a long time BMW driver, owner or enthusiast you may be surprised to learn that installing a new battery is no longer an easy 10 minute DIY job on modern models. Starting around 2006-2007 most BMW cars require the battery to be programmed and registered when replaced. This is because of more complex power management and battery management software. When replacing the battery, you need to tell the car that a new battery has been installed and input parameters such as the amp hours capacity and type of battery (AGM vs. lead acid). While this seems like an unnecessary hurdle to DIYers, it’s actually just a result in the evolution of technology that makes a lot of sense. If you’re still driving an E30, E28, E34, E36, E32, E39, E53 or E46 then there is no need to program a new battery with software; you simply remove and replace the battery. Nice and easy. Thanks to inexpensive scan tools made for BMW’s found on Amazon, you can program and replace your battery yourself …

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 …

Why is My BMW AC Blowing Warm Air?

As we drive through the peak July heat of Summer, one question I’ve been hearing a lot from my subscribers is about your BMW air conditioning system issues. There are three really common issues across all BMW’s with respect to inoperative or weak AC problems: The center control knurled stratification wheel knob is poorly adjusted The electric auxiliary fan behind the front bumper has failed The AC freon leaked out and needs a recharge of 134a The first place to start diagnosis is the easiest: check your center control knurled stratification wheel knob in the center of the dashboard. Every BMW since 1980-something has one. And it may be the most misunderstood HVAC control knob of any German car out there – even today! Here’s a background on how this HVAC control knob works and why it could be causing you to have warm air blowing in the Summer and air too cool blowing in the Autumn and Winter. The often overlooked stratification knurled wheel for the center vent is often the cause of heating …
