Hi guys, I'm a newbie here, and I guess what made me register here is the fact that I need your help!! I already did a search and found no definitive results.
My car is a 2003 Jetta tdi 5-speed, all stock so far, which was suffering from many problems. I had the injection pump replaced with a new unit, new fuel filter, and a new maf sensor.
All the old symptoms and codes are now gone, car drives fine, but has a slight shudder at idle when cold.
The code I get via the vagcom is "fuel quanity adjuster upper limit reached".
So i checked on this forum, and replaced my fuel filter again, no change, same code.
I checked my iq settings, it was at 3.5 at idle, so i tried taking it to the upper limit, 5.0, and still no change. Same CEL. Then I tried higher, brought it to 7, still the same code. Then I brought it back doen to 2.5, same code. Now I brought it to 4 and left it there for now, but still the same code.
At first i was able to clear the code, and it would take a few minutes of running before the light would come back on (along with a flashing glow-plug light) but now, the code won't be cleared! Unless i disconnect the battery for a bit, that is.
So, I don't know what else to do! Can anyone help asap?
Thanks in advance guys!
