Display Faulty error
I can start the car, after it start, it throwed one more error saying 'Faulty Battery (or sth) - Electrical consumer Switched off'.
Weird thing is, radio, power window and aircon is working fine (maybe it run from alternator). The only fault i notice is the petrol gauge, it disappear, no bar at all, i still remember the car is half full. Then, i switched the car off and put the key on position 2, only one error remain, it's the fault display error.
Any idea to reset the Display, or do i have to visit the workshop to fix this?? also, the smart key seems to crap itself, only want to open and locked the car when i point it towards the driver door and cannot open the boot/trunk anymore, i replaced the batteries with my C class key and nothing wrong with the bats, works fine with the C. Connected problem??
Thanks before.
The car is 2003 E240 (W211).
