I would like to ask you experts how often does throttle body fail on our car. I have a 2002 turbo s, currently has 166K, the throttle body has been replaced about 3 years ago when it was at 138K and now it starts to fail again. When the RPM goes above 3000, the speed would drop and the turbo is trying hard to spool up. No check engine light, no codes, but I had a mechanic scanned it via VCDS and he stated that the throttle body does not respond to the computer and suggested it could be the electric module that's failing. The throttle body was purchased through VW dealer, not a third party part. I'm just shocked how quick a throttle body could fail. I thought it was ignition coil that's causing the problem but after having it scanned, it appears to be the throttle body. Can anyone help address/solve the problem? Your help would be greatly appreciated.
