Hi all
I have strange problem on my 2003 320i (M54 engine) sometimes it drives perfectly and accelerates normal but sometimes it losses power, on acceleration rpm raises slowly and engine has a smothering noise (especially on high gears). I have inpa diagnostic tool but no one error found, all sensors working normal. I always use same 95 octale petrol

Hi
Still have a problem with power loss and slow acceleration, I bought OBD wifi scanner and saved some log files

cruise highway log files, average speed 70-100 kmph

warm engine idle log file
https://www.dropbox.com/s/axqz9rw0s9w4we6/CSVLog_20151208_201027.csv?dl=0

I got only error P1619 (Map Cooling Control Circuit Signal Low) but engine temperature varied about 96-100C degree. can anyone tell me what is the matter with my car? :)
