2018 M3D (nonP) and have had a clunk for awhile, normally on “resume acceleration” (let off, get again on whereas transferring) or when coming down the bottom of speedbumps and so on.
Took to 1 SC and so they changed a bushing on considered one of my drive shafts claiming it was a identified problem on some 2018’s nevertheless it was “laborious to breed”. WelI, it fastened one symptom however the different continued. Of their protection, it appears to happen much less within the colder months which this was.
Took it to a special SC lately and so they anticipated it to be higher management arms. The gorgeous rapidly indicated UCA’s on either side had been good, and never the trigger. They dug into it extra and are capable of replicate the noise at will (sure!).
They requested a bunch of questions on when this began precisely (guessing they assume probably meeting problem).
They gave me a loaner and have now ordered this bolt:
Half #: 1119905-00-A
Wanting round, I discovered minimal search outcomes apart from a useful elektromobili.ru website that has the next graphic:
The outline references Half #19 and the schematic is for the excessive voltage battery meeting.
Has anybody else had any dealings with this or any battery shell elements replacements?
Or any ideas on what may need brought on this to be zeroed in on?
Perhaps only a lacking bolt not put in since day 1? Eek.
Thanks for any perception’s y’all may need
