Default Boost won't go above 5 psi, ideas? Help greatly appreciated...

ASP software, car is at dealership getting a new passenger side intercooler. They went for a test drive and the car wont boost above 5 psi. They thought it was valet mode, I thought it might be limp mode. The Audi mechanic there works wonders with B5 S4's and he is baffled. Thanks all!

start simple, tell him to check the throttle body boot, a proper check will require removing it.

Default Have they even plugged a VAG into it? I'd bet there is a code there.

I agree with the rest- if this guy "works wonders" he would know that it is in limp mode.

why is it getting a new IC? Check for leaks and codes.

Default Who knows, his rep is what the other "mechanic" told me

Car went to a body shop to get the bumper aligned from a fender bender months ago and now is at the dealer for a new IC, makes no sense.

Any mechanic worth his rate would pressure test and look for codes.
