Mercedes ML diesel multifunction steering wheel issue

Had a similar issue on a BMW 3 series Steering controls went haywire It was a faulty slip ring rotary coupling within the steering column This maintains electrical contact while the wheel rotates Is the 95€ quote just for diagnostics or does that include parts and labor

The 95€ quote is supposed to cover everything But does that require replacing the entire steering column I thought the control module was separate

95€ all in sounds cheap The rotary coupling is part of the steering column assembly but it's sometimes available separately The control module is usually separate but if the slip ring is faulty it can prevent the module from receiving the correct signals Given the price it's worth letting them do it but be prepared for them to say it needs more work

I'll let them proceed with the repair It WAS a broken wire inside the steering wheel They resoldered the connection cleared the error code and everything is working perfectly again 95€ well spent
