RE: BMW E83 A1 error - MRS: No message from DSC ...
I had a long drive - 1800km, mainly highway.
The error logged (but no dde active on dashboard) was:
497D Pressure sensor, plausibility while afterrunning: Exhaust pressure before turbocharger not plausible with ambient pressure
For this error - ISTA recommends to replace the exhaust backpressure (the round shape one)
Interesting to notice that regeneration was done 2 times after 700-800 km ... usually when driving around the city regeneration is done each 300-400km.
Lets see these days if also first error -4933- will be logged while driving around the city.
