My friend had the same problem, when his one of the first m3 e92 MDCT came to Moscow. He came to perform a service and a mechanic read a service manual where it was said to change all the fluids in the car. The mechanic emptied the MDCT and then it turned out that they didnt know what oil to fill in, because it was the first one m3 MDCT they serviced. The car was staying there for three weeks
, until BMW send them an official explanation that THE MDCT OIL IS A LIFETIME ONE AND THEREFORE SHOULD NOT BE CHANGED.
