i purchased a new MAF from a company in CT called FCP Groton. the first one i recieved triggered many check engine lights, figured it was defective, asked for a new one. they sent me one no other questions asked overnight...now installed i see boost numbers at peak of 14 and that never has happened before. but after a few spikes, im stuck to 5psi till i turn to the car off then back on. limp mode? please help im lost...

do you have access to a VAG-COM? Also, how many miles after new MAF install?

or chipped...any other engine related mods?

Second....while you may have cleared the CEL, it could take some time to clear the ECU of errors. There is no good way to do that in VAG (if you have it)....you have 2 options, drive it and it will clear as the car adapts to the new MAF. This will take approx 40-80 miles as it seems each car is a bit different. Or you can disconnect the negative terminal on the battery for 10 minutes. If you choose the latter, have your radio code just in case. Once you reconnect almost all of the ECU mapped errors will be gone.

If you are not chipped, 14-15psi is about all you will see and the car should settle back to around 10-11psi when accelerating....
