328i 2013 - Comfort Access stopped working all together

toha · 07-11-2020, 01:31 PM

Hi guys, my car's comfort access stopped working - can't open or close with door's handles touch, or using trunk swipe. It was working fine before. What should I check first? I have two keyfobs and it's the same for both. No low battery on fobs or car - both normal. Is there a fuse I may need to check? Anyone know which fuse and where by any chance?

Try a diagnose first to see where the fault lies.

I used Bimmerlink and it shows driver side antenna line break fault... could it cause entire CA system to fail because of one line break? I would expect only driver side not working, but entire CA is not operational... does one line break like this in one door's antenna cause entire CA to stop functioning?

Fix the broken antenna line and you'll know. Anything's possible with BMW.

Anyone know where that antenna is located though? I can’t seem to find any diagram that shows where it is behind the door’s panel....
