There may be a possiblity of doing damage to the turbo if you continue to drive it this way. I would recommend either taking it to the dealer or a reputable repair shop in your area to have this repaired as soon as possible, as to not risk damaging the turbo. Hope this helps.

SOURCE: Overboost condition

Hello, your car is probaly a variale vane turbo fitted and all you need to do is seperate the VNT part of the turbo, give it a good clean with brake/carb cleaner get rid of the sticky oily residue which makes the vanes stick on turbo causing a overboost fault, a delearship might tell you that your car has been remapped at some time setting the boost RPM at like 14 or 1500 and it should be like 2200 I do not know the specifics on your vehicle but a good auto manual will tell you at which RPM your boost should build. I would have a diagnostic done and see if this is your problem, if so do the above and go back and see if it fixed your overboost problem. If not, you will need your ECU remapped. I hope this fixes your problem!

Very difficult. You have to open the inside access door on the drivers side, remove the amp and wheel well cover, pinch the tabs and the bulb cluster will release. The taillight assembly is bolted from inside of the car, so it can't be done outside.

2002 vw jetta 2.0 code P0420

The error code definition reads:

"Catalyst Efficiency Below Threshold Bank 1"





It's possible it might be the oxygen sensor, but it's more than likely the catalytic converter. This is a relatively common code for VW's.

You can google "p0420" and see the posts...

Could you tell me what the Jetta TDI diagnostic code 638 is?

There is no DTC codes for VW 638, your going to need to get the right code There is a P1638 and that is Data Bus Power train missing message from clutch control. which means there is not communication from the TCM to the clutch control. (there is no signal from the Sensor to the ECM) replace sensor and check the wire harness. Good luck and hope this helps.
