Hello folks, I just picked up a 2002 Jetta. 237 k miles, 5 speed standard.
I picked it up at a good price, the previous owner thought he had a dead turbo. I was not so sure so I pulled the trigger. No code now, probably need it to cycle. I have a ZURICH code reader, pretty good reader. The only thing I see is a #1 glow plug is dead. No problem. I checked the vacuum lines using a generic diagram, replaced many bad lines and checked routing. All seems to be okay now, maybe??? The turbo will boost fine about 5% of the time, the rest of the time SHE ACTS DEAD. I have a hard time getting her above 3000rpm, but sometimes she comes alive and runs normal, 80mph easy. I know I need to give you some codes, but don't have them yet. Being a stupid idiot that I am, I tried hooking the vacuum from the vac pump directly to the actuator valve on the turbo. Nothing! I sucked on the actuator hose to see if the diaphragm was bad, it appears that it will hold the vacuum. I'M thinking maybe the actuator is not opening the waste gate allowing the turbo to spool. But sometimes it does, folks i'm a tad perplexed.
