Anyone experienced on this? How did you know it might need to clean up? Thanks.

Could you elaborate on clean up? I'm not quite sure I know what you mean.

Unplug it to clean up inside. Sam told me it may need to do so.

I think he might be refering to the vanos filter that needs to be cleaned at oil change intervals. It is part number 23 in the above link.

O...thanks, it may the one!!!!

Therefore, is it a part that difficult to replace?

I mean unplug the whole vanos from the engine.....

easy to take apart (i meant the whole vanos)...but your ordinary garage will not be able to put it back...trust me...there are not too many garage that can work on our m3 in hong kong
only that you can clean with ease is the vanos filter....but they seldom got dirty unless u never change your engine oil
