egr valve causes these fluctuations . remove the vacuum hose which control
valve and stuffy with a screw . if fluctuations cease , remove and clean
the EGR valve . If after cleaning and reconnection fluctuations reappear.
Cancel or replace EGR valve . I had the same problem on a 2000 VW Passat
1.9 tdi tiptronic gearbox and it seems that the automatic often experience
this problem
same thing goin on here, I even pulled the valve cover to check the cam
lobes and lifters, everything is fine, cept it just kinda has little
hiccups at idle, I shall have to have mine adjusted too!
I have no Idea. They just told me 3 out of the 4 injectors was faulty. The other 1 was already replaced before I bought the car. Its a expensive process if you dont have warrantee. I have never ever experienced a dpf regen cycle?
Hi, interesting, i resolved mine in the end with a dpf regen program update, wonder if they did this whilst doing your injectors? from what i found out all 1-6tdi 09/10 all started there life like this, it occurs when the dpf regens but a software update in 11 fixed it. I wonder....
