Well I have and 1994 for golf with the 1.9 TD... My problem is that it has no power, it barely makes any boost. The turbo was replaced last summer so I know thats not the problem... have any of you guys had this problem or have any idea what it might be?

thanks in advanced,
Peter

A diesel thats starving for fuel will not make any boost and will be gutless. Have you changed the fuel filter?

Changed the fuel filter back in october

Any smoke? Noise? Did the power loss develop slowly or suddenly?

Funny this should happen to you because it happened to me a few weeks ago. All of a sudden my car would only make 3-4 psi when it used to make 10-11 psi. My problem was with the bolts holding the wastegate actuator to the compessor side of the turbo. One bolt completely fell out, probably rattled loose, and the other one was backed out a 1/4". I could grab the whole actuator and move it around half and inch. I'm not sure that the bolt size is though. I bought a 1/4"-20 UNC and M6-? but neither fit. I'm guessing it might be 1/4" 28 UNF. The turbo on my car is a Garrett by the way.

As an aside, my car has been getting better mileage without the additional boost so now I want to rig up something where I can dump boost when I want from inside the car.

no smoke or anything... well im car never made full boost utill it was warm (not sure if all TD's are like this) It seems like it doesn't warm up but I get hot air through the vents.

farkman i'll check to see if it's the same thing in the morning

It appers that all the bolts holding the wastegate actuator to the compessor side of the turbo are there.

But I took of the hose coming from the turbo going to intake manfoild and it was full of oil. So I'm assuming that this oil isn't supose to be there and was wondering what are some of the cuases of getting oil here?

If that hose is full of oil its most likely from the crankcase vent, which goes into the intake tube. How much oil are you taking about? You said it was a lot so I'm thinking that there might be a pool of oil sitting in the turbo, since it's the lowest point in the intake. This could be why your not getting boost because the turbo can't spin in the pool of oil. Have you taken off the intake tube between the air box and the turbo to check for oil in the turbo?

My buddies '93, had no boost either, and he found the turbo full of sludge crap, therefore it couldn't spin. He just cleaned it up, and it ran great after that. So have a look insideat the face of the turbo, and try to turn it with your fingers, it should spin freely. Then go from there. Keep us posted.

Maybe your car is only out of timing. But you should notice some exhaust smoke.

Pfhettinga · « **Reply #10 on:** March 16, 2005, 12:49:29 pm »

farkman then hose is more just lined with oil... As for the intake tube theres barely any oil in it and the turbine spins freely. I don't think it's the timeing becuase it runs fine other wises and doesn't smoke, well it smokes a bit when you 1st start it.

Moonstone when your buddy cleaned out his turbo and all, I'm assuming he had to take it off

from what I can see in the pic, it looks like your throttle cable might be way out of adjustment.
Get a helper to put the accelerator pedal all the way down, then see if you can turn the throttle arm by hand any further. When set up properly, the throttle arm should rest against the idle stop with your foot off, and against the max power stop when your foot's down.
With the pedal down, if you can turn the arm by hand further, grasp the throttle cable housing and pull it away from the pump towards the driver side of the car, until the throttle arm touches the max power stop. then reposition the holding clip (if there is one) in the appropriate groove to hold this setting. When you release the pedal, the arm should then rest against the idle stop.
Also make sure the floor mat isn't getting inbetween the pedal and pedal stop.

This might be the cheapest tripling of HP you'll ever have!

Pfhettinga;

My buddy just pulled the rubber intake tube off, and scraped some stuff out, while sucking it with a shop vac. Said it worked fine after that.

finally got to take a look at his car,
what happened was...

there are two solenoids on A/C golfs on the right inner fender one controls vacuum to the wastegate so that when the throttle is released the wastegate opens. the other sends vacuum to the Idle control to bump it up when the car is cold. It would seem that the wire from the idle bump was hooked into his wastegate control so that his turbo would only spool when the car was warm. Add to this the fact that his bad thermostat is preventing his car from warming up and there you go, no boost ever. Pulled out the whole wastegate vacuum system since he already moved the throttle switch and no more problem.
