The door are not locking and unlocking
I have a 02 s320 cdi. Suddently the car stopped to lock and unlock with the key and had to unlock with metal key now i also changed the 20A fuse down there but no progress other than car making sound like 'tuktuktuktuk' each time i would press the lock and unlock button on key. Can you guys help what that could be and how to fix this problem.
Thanks
