Does anyone in the Utah area have a vag-com system I could borrow to see what a going on with my ahu. My boost gauge is only saying it's getting 5 psi. Never owned a tdi before so not sure if it feels normal and my gauge is wrong or if the computer is keeping it from boosting more. Any help would be appreciated

You would know it if it's only getting 5 psi, the thing would be a dog incapable of getting out of its own way.

I would look to your gauge hose or perhaps the gauge is sticking. Take it off and using a bicycle pump try to pump it up. I had one that was stuck once but I knew it was the gauge since the car had great power.

I went through it all last night. Checked for boost leaks, checked the line to the gauge and found no kinks. I took the gauge out and couldn't get it to go past 5 psi with a pump so I need to take it back. Thanks for the advice
