Hey all,
Recently picked up a 2001 Golf GLS 1.9 TDI with a staggering 408,000km on it for $800 CAD (500 american or so?). Was owned by an older fella with a towing company, he used it to drive to his yard, so it did a lot of short short trips with minimal warmup. Brand new clutch, battery, timing belt, and the body is in good shape (very very minor rust on the lift gate), and the interior looks better then most 100,000km cars. All the vacuum lines look new, as well as the glow plugs. Knew she was gonna need some work, and that’s why I took her on. I figure in the end I still come out with a very cheap TDI and keep the KM's down on my M3. All in all it seems like a well kept TDI (versus some I saw asking 2-3 grand and being beat half to death).
When I got it the glow plug light (flashing) + CEL was on. Ran it on VAGCOM and found a few little things, alternator is coming up on the end of it’s life, a few little ghost codes that didn’t reoccur, and a dead connivence module. Sorted that out with some general tiding up and cleaning connectors, as well as fixing a ghetto rigged EGR delete someone had done with a screw. Seafoamed the car, and that got rid of it’s mildly clunky idle. Threw in a new fuel filter as well. There is also a ghetto rigged high idle switch in the dash that seems to do… Nothing. Raises the idle by about 100rpm… Now she starts and runs fine. No weird sounds or shaking.
Now for the problem. She feels like a NA diesel. I literally cannot accelerate up a mild/steep grade. I get up to about 60km/h in 2nd, and it’s game over. Cannot hit the speed limit. I have driven 2.0TDI’s before, and they definitely had noticeable boost to them. There is zero increase in RPM gain over the range. It just steadily creeps to redline. And no torque-pull. Vacuum tested it last night, right of the tandem pump, and I'm pulling 5mmhg only. I'm guessing this is why the turbo is seemingly non operational.
Anyone have any other ideas on it?
Thanks for reading!
