Hi guys,
I don't have any fault codes but performance seems up and down in my old E39 528i. Maybe it has too many miles on it now, Im at 206k miles.
I'm looking for advice on what sensors to renew that affect engine running and performance. Crank sensor was recently changed. I will get a new camshaft sensor and MAF.
Do I need to renew all lambda sensors? What about the likes of air intake temp sensor and coolant temp sensor?
Anything else at all?
