Check the air to air cooler, and make sure none of the hoses have a hole or are collapsing, also check the turbo fin shaft.

Turbo / Boost Issues


Sounds like a faulty boost pressure sensor or waste gate. I would check the waste gate first. Sounds like it is opening to soon and letting the boost out, than regaining again.

Turbo cuts out under normal driving


That sounds like turbo overboost, ECU cutting the boost off. when you try and boost again feels like your hitting a brickwall, or when it happends feels like your hitting a brick wall...turning the car off resolves this.

Reset your ecu, disconnect the battery for 30seconds - 1minute.

Take off power fluctuation.


Sounds like you have a problem with your turbo or your turbo waste gate Check your boost output from your turbo guage. That enggine under heavy load should produce between 20 and 25 lbs of boost.

Turbo keeps cutting out, mainly on incline or declines, could this be fuel filters.


Could be one of many things. First off if you can"t remember the last time you changed the fuel filter (there's only one, and it's in plain sight) then do it. It should be replaced every 20k miles. If i were to guess though I would start to look at the turbo actuator system. The turbo is engaged by vaccuum. there's a vac pod on top of the turbo with a vc line going to it. At idle, when you don't want boost there is no vaccuum sent to the actuator pod. The pod is connected to vanes in the turbo that direct the exhaust flow either into or around the blades. Under full throttle vaccuum is sent to the pod to move the vanes inside the turbo to direct exhaust into the blades causing it to spool up and give the car some zip. I have replaced quite a few of the pods. Here"s some more to think about...

Vac is generated by a vac pump off the back of the camshaft. Check to see if there is at least 15" of vac.

VW doesn't provide a port to measure boost. Anywhere. In my opinion all turbo cars should have a boost gauge. Either install one- it's not hard, or get someone with a VAG.com type scanner and see what the boost is. Stock I think was a lazy 13psi under acceleration

Use a vac pump, hook it to the line going to the vac pod on turbo and make sure it HOLDS vac.

other poss. causes- vac leak somewhere else, check all lines

turbo crusted up inside

something else weird.

When you find the problem please let me know. Im curious...

Jumping or jerking when i accelerate


I had a turbo renault , I cranked the wastegate down to increase boost and had same problem.
There was a sensor that cut the ignition if the turbo was over pressuring. Was a pretty violent jerking, felt like it was tearing the engine mounts out.

Boost problem


Check vacuum pump. Be sure lines are good all the way to to wastegate soleniod. be sure wastegate solenoid has power. Confirm rod is connected to solenoid and turbo wastegate.
Also check all plumbing for leaks.
