hello all. while checking out tdi club site, i was directed to this site by seatman. i have a 99.5 jetta tdi and have low boost. i believe my problem is the turbo actuator, but i haven't removed hose at actuator to rule out a bad hose yet. just wondering, as my car has .216 nozzles installed, how touchy is the adjustment on the rod for the actuator? wouldn't want over boost by being off just a bit on the length in case i have to replace it.

It's touchy but try marking the rod with paint. If you suspect the turbo actuator, take a look at this article: http://www.myturbodiesel.com/1000q/a4/VNT-wastegate-adjust.htm , make sure you vacuum test it before adjusting the road length, good luck! A vac tester is pretty cheap so get one so that you start simple.

i just replaced my vnt actuator. went for a drive with vag com. actual boost was at around 2500. when i got home, noticed engine missing and stumbing at lower rpm, and it smells like it running rich, very strong exhaust smell. any ideas? how do i bring down the boost?

Did you go through the set up and adjustment faq?

all adjustments on new actuator were sealed. took off old one , put on new one .

Might be worth going through the limp mode faq and run through some of the stuff in there. You could check the vac lines and intake pipes too incase something's loose.
