I read that thread before posting but thanks.
This is my second R. The 23 had exhaust issues as well. Fixed by dealer. Also had the stalled start. Fixed by dealer.
This is most likely the exhaust actuator for the valves but wanted to see if anyone else had an opinion with a different video since that thread doesn’t have much in solutions. Every new manufacturer has issues with cars being delivered these days regardless of price, which is unfortunate, but just a standard since Covid I’ll just get this one fixed and keep it because it’s awesome. Sorry you sold yours.
