So I just got one this year with 100k and it still feels "like new".
I'm going to treat this like my m54 engine. Looking out for oil leaks, vacuum leaks (which cause engine hesitation/misfire). The MAF/O2 sensors. At this mileage first job I will do will be the spark plugs. Within that job I hope to explore the engine some more. I too searched for "common problems" for the 640i, there don't seem to be many! ither than the usual valve cover/ofhg oil leaks to look out for. It's also nice driving a petrol BMW that does not need an oil top up every 1k miles! |
