I’ve seen this issue too online. I’ve checked all my handles and they all feel normal.

If that doesnt make a difference then like the other member posted above, feel all of your handles when its cool out and see if any are warm.

Also there are multiple antennas, if your rear hatch will pop open when its locked from touching it but your front doors wont, good indication that the front antenna needs to be replaced

I will remove the odb2 attachment and see if it works. But I’ve had that obd2 dongle on since I got the car and it never caused the system not to work.
None of the 4 handles work and neither does the hatch.

This was the first thing I did. Protools did not show any faults.
I cannot find the comfort access module on protools either. I remember there being a specific CA module right?

Yes, none work. On my e91 it was broken wire going to the hatch antenna. But that completely stopped the fob from working too.
On my e70 the fob still works, but half of the time I have to press the buttons down hard and/or multiple times.


I’m going to get another new battery for the fob tomorrow, if that doesn’t work, I’m taking the car battery to get charged and if that doesn’t work...
