Morning,
Recently I have noticed my B7 2.0 Tdi 140 to have a hesitation / stutter at around 1600 - 2000 rpm when accelerating, especially in 2nd and 3rd gears. It doesnt do it every time but it is happening more regularly.
Does anyone have any advice on what I can do to resolve this issue?
Thanks,
Chris
Hi all,
I have a 2007 2.0 tdi (170) and have the exact same problem.
I had a break down a while back due to faulty injectors, one failed but two were replaced and the car ran ok. Then I needed a cam belt change and Audi changed the other two were replaced. Since then I had the same issue as above, a slight stutter between 1600-2000 revs. Took the car back to audi but it was running fine when they came out for a test drive.
few days later it happened again. went back to audi and again they ran a diagnostic no fault codes stored and running fine again.
However, yesterday it had a major kangaroo episode (in fourth gear at 35mph), happened in 2nd gear (slowing down) and again in 1st when I tried to setoff again.
took it into audi, they rang this morning, still no fault code and running ok again. However they did say that say that someone else had the "exact same issue" but this caused a fault code and was due to the actuator spitting in air with the fuel.
They have ordered one and it will be replaced monday. I did a search within this forum and sure enough "actuator" and 170p a4 all come up with this fault, but a change of this part has again often not resolved the problem.
It seems this is due to the change of the injectors (which were a recall - unknown to me, but changed "by courtesy" when I had my cambelt done.
hope this helps others, and fixes mine
