Mein Auto: 2010 328xi
2010 E90 Comfort Access Problems???

Hello,

I just purchased a 2010 BMW 328xi and am having issues with the CA system. When I first purchased the car I was able to get in the driver's seat and simply press the brake pedal and push the Start/Stop button and my bimmer would start up. Recently that has not worked and I have to put the FOB in the little housing area to get the car to start now.

Why did it start requiring me to pull the FOB out of my pocket to start the car? Is there a way to turn this feature on and off?

Obviously this isn't a pressing issue, but I would like to know why this isn't working. I'm taking it to a dealer next weekend and will ask the same thing but figured I'd try here first.

Thanks in advance.

Lots of possibilities to be found in the 'search' function.

Could be a couple of things. It COULD be the battery in the FOB is low. BMW made it so that keys WITH CA can have their battery replaced (just pull it out and replace with a battery, they're cheap as hell), but keys WITHOUT CA, you can't really replace the battery yourself.

That being said, it could be the FOB sensor in your car (which I believe sits right behind where you insert the key) is wonky. In which case it'll be about $6-700 bucks out of pocket (not counting warranty) to replace. I remember a topic like this a while back with a similar issue. Get it checked out. But you should have a warranty either way, so nothing to really worry about (other than a few hundred bucks out of your pocket if it ends up being the sensor).
