I'm Herman the German.
I found your forum this morning, because I am looking for some help with my problems. Since 2 weeks my E300TDT has got electronic problems like this: the direction indicators and the wiper and the electric windows still work, but during their work they stop for half a second or they work on for half a second after having them switched off.
Do you know, which parts could cause theese irrugularities?
What I already did:
To reset the control units I took away the battery for half an hour.
I checked if there could be water in the control unit box
I checked the relais
I tried to calibrate the electric windows
No success at all!
Who knows it?
