Comfort access - automatic trunk will not open/drivers door switches are dead

tommy_sn · 10-12-2019, 11:44 AM

Hi
Any suggestions what that can be wrong when the trunk will not open when you stick your feet under the sensor and nothing happens?
It workd for some days ago - but now nothing happens. The trunk can be opened with the key-fob, and the handswitch.

Is ther esome settings or other thing that can block it? The cables under the feder is all connected - I have checked that.

Drives door switched problem explained some post below..

I don’t know of any settings that would disable it... might need to take it to a dealer to have it investigated. Sorry I can’t be of more help.

Works on and off for me

is something blocking the sensor? did it get too dirty?

tommy_sn · 10-13-2019, 04:43 AM

Its clean..and all the wires are in place. Took of the cover just to check.

Hmm, no idea. Maybe tey the dealer? Mine works 100% open and close without issue. Are you placing your foot there, or doing a quick "kick" mition?

Tried both. Had the system on a F30 - worked with no problem. So looks like I have to contact the dealer..

I've had the same problem.. It happened to me just this past Thursday. I recorded a video of it, because it is humorous how many issues that I've had with the G20. My wife thinks I'm making them up — so I've just started documenting them.

Found another problem - the switches on the drivers door is also dead - connected to the problem with the trunk? No light in the switches or in the lock-window button.

The windows or mirrors dont work from there (I have the light strips and the lock/unlock button work). Mirrors cant be folded.
Windows can be uses by the switches on the other doors.

Any trick to reset this?
