Does anyone have access to factory maintenance schedule for a 135i N54.
I want to know recommendations for maintenance intervals for pulley's, belts, timing chain, plugs, coils etc? Also intervals for all other planned maintenance items?
Great Thanks - at least its a start. I note no mention of scheduled timing chain replacement or tensioner replacements? Just Pulley Belts. Does that mean you never replace?
No if you do research the tensioners are always replaced with the belts. When you buy the kits it comes with everything incl the tensioners. Was reading about this today as my 120k service is coming up
