Boost isse... plz help me
Okay .. I just got my gauges installed and I found out that after the car is started & the blue coolant light is turned off.. the boost gauge shows up to 15 PSI when I accelerate.. things are fine and car pulls just fine .. however after a few minutes of driving the boost does not go above 5 PSI & the car doesnt pull as good ... so can I have some idea of the cause maybe ?
Car is a 2001 1.8T (Limited Millennium Cup edition 4 Dubai) and is said to be 185HP ..car is totally stock I will really appreciate your help

Did you have this problem before you installed the gauges? Where did you tie in the boost gauges? sounds like it could be a vacuum problem.

Sounds like an overboost problem which is resulting in limp mode.
Any error codes?

First thing that comes to mind is the waste gate on the turbo. I am pretty sure this is vacuum actuated. Start checking intercooler piping and vacuum lines, looking for any worn,torn or cracked hoses. Sorry not much help. Maybe someone eles will have a few ideas. I really dig your car. Tell us more about it.

5 PSI only is soft limp mode. Scan the car. Something is not happy. Do you have a chip? If not 15PSI will cause the car to protect itself by limiting the boost. You can do a search for "diode mod" either on here or the 1.8T forum on Vwvortex. This will trick your cars engine control module in to only reading 5-6 PSI and will prevent you from going in to limp mode.
