RE: BMW E83 A1 error - MRS: No message from DSC ...
You say it moves with some resistance. BUT does it move BACK by itself if you move it fully?

Disregard, I was thinking about pneumatic control, this one has electric.

Then the question is HOW could you try moving it? Have you EVER removed the electric actuator? It is factory calibrated and supposed to be NEVER removed! If you ever released it's bolts, you broke factory calibration and that would explain your problems.

IRL it is possible to get it more or less into somewhat correct position by multiple tries and fails...

Indeed, it is electrical - i have to move it by hand both direction - and it was never ever removed - i am sure about that.
I found also the test, executed 3 times and it is moving back and forth each time (multiple times during 1 test) - about 15mm.

Funny part that now it started to manifest pretty much each drive in the city. Not sure if it is related to DPF which soon will need to be regenerated (it was like 280 km from last regenertion) but even me - i have doubts.
Most probably I will end up mounting the second turbocharger - the error drives me crazy but thats it ... it insists to give me the chance to learn how to replace a turbocharger on N47 smile.
