I know its been some time you wrote on this thread, but I wanted to ask for your assistance I hope you are still active here.
I have a 2005 W12 7L which has the two door handles on the passenger side shorted to ground. Some time ago I got the drained battery issue(main battery is new 4 months). Luckily I got it started from the aux battery.
I followed your instructions and unplugged the connectors in the two faulty doors which you had highlighted earlier in the thread. Now the errors for the door handle buttons are gone, and the car does not lock unlock itself when I am near it with the key in the pocket. I have unticked the Auto lock/unlock in the comfort menu.

However I am seeing a new error(wasnt there before):

00180 - Access/Start Authorization Antenna; Passenger Side (R135): Open Circuit

Which kind of makes sense as I have indeed unplugged the cable. However why is it not showing it for the rear right door too (I unplugged that one as well). I am worried that almost all threads for battery drain problems with defective KESSY module have this error in their scans.
1. My question is - when you unplugged your wires, were you getting the above error code?
2. Isnt the above error/issue more likely to cause a battery drain(not allowing the car to go into standby) than the handle buttons being shorted to ground


BTW: I am Bulgarian too.

Hi, you can start by the simple things first.
Try disabling the auto unlock function in your MFD.
It will be under comfort and you have to scroll all the way down, see if this cures your drain.

For the sake of being thorough these were the errors before I unplugged the couplings in the right side doors:

I do not have any other errors. Will the car go into standby with the above error?
