Hi all

just wanted everyone’s thoughts on preventative maintenance on this model. I have the 640 i M-Sport gran coupe.

apart from the dreaded yellow grommet issue, is there anything else I need to be doing ? I’ve already had an interim oil and filter change done (In between the idrive services) but anything else I should be wary of ?

I understand this model has the n55 engine. I’ve read the oil filter housing gaskets have issues, but is this common?
Is there anything else I need to be mindful of?

and would warranty cover any such issues?

thanks as always

Congratulations! I'm not quite a month into my 640i GC. It's a beautiful thing! Keen on any responses you get but I've had two m135s with the n55 and never had an issue although the most miles I've done on one engine was approx 48k.
