Hello dear six-piece community, I own a nice 650i from the year 07 with the N62 engine. For about 3 months the problem has occurred that the engine had strong speed fluctuations and went out afterwards. The solution was to read out the error with an OBD plug and delete it. I then changed the air mass meter. However, the problem did not disappear. Next I changed the membranes of the crankcase ventilation. The speed fluctuations are gone and the engine runs The following errors are stored in the memory: 0029ED: DME: mixture adaptation, lower speed range 0029EE: mixture adaptation2, lower speed range The car is running normally. Does anyone know these errors and the reason for them? Thank you very much for your help!
