Hi all I have just got myself a 535d 2004 with a problem when driving a 1200rpm - 1500rpm its rev up and down look I heavy footed and messing about,I have checked the MAF cleaned it out,checked pipe and can't see anything wrong have anyone get ideas on what it could be.
If Im parked and have it at 12 - 15rpm then this not happen?

Welcome to the forums.

I don't completely understand what's the problem, but if you feel like there's no turbo and you've checked the things you mentioned, it could be the DPF.

ps. Your diesel revs pretty high lol ! Just kidding...

pps. Or do you mean your car changes gears up and down even when driving constantly?
