There are a broad range of engines fitted to the M-Series - petrol & diesel
If you have a general Engine query, and you're not sure which section to post in, please add your question here (it can be moved to the correct section for you
) ...Most importantly, please include the VIN engine prefix in the topic title, and a little bit more info about the exact engine you're asking about at the start of your post - this will be a big help!
Thank you!
