2012 E71 Comfort Access stop working
Hello, My comfort access for all my doors stopped working the other day. I have changed the batteries on my key fob and checked the fuse in the trunk and everything looks good. It's just my doors, it is not affecting my comfort push start or my trunk comfort open. So I don't think it's my whole comfort access module. I ran my bimmerlink and it shows 4 errors. I also purchased a new driver side door handle, but still the same results. Anyone seen this before? Trying to fix on my own before going to dealership.

I have checked the fuse and replace them all just incase and still the same. start/stop button works fine, trunk comfort access works. Just the doors that have stop working. Very weird. I saw a used comfort access module on eBay but if the start/stop and trunk opens works, could it still be a faulty CAS module?

I’d love to know if you resolved the issue, I have an 2012 X6 35i and the comfort access completely disappeared. In order to start the vehicle I have to now insert the fob like a non comfort access BMW.

Check fuse #132, I'm sure that's blown. Key less start/driving is called Passive Go and is separate from your Comfort Access. Are your door handles all working?

You’ll have to test each door handle in that case. One of them is bad. It’s pretty easy. Takes about 5 min per handle. Just unplug one at a time and see if your CA handles start working again. As for keyless, replace the fuse. That should come back right after.

So… I found the blown fuse affecting the Passive Go 7.5, I replaced it and it immediately popped, I thought it was a freak accident and replaced it again and checked it and yes it popped instantly. How can I find the issue?
