Hi all,
This is my first post to this forum. I have been quite active on tdiclub.com and vwvortex(to a lesser extent),
Long story short... I have been trying to diagnose a scraping/metallic exhaust sounding noise for over 3 months on my car.
The noise starts just as boost is kicking in and lasts until about 2600 rpm. My engine also feels like it's surging or being overpowered.
There are no boost leaks, vaccuum leaks at all.
My car has been looked at by myself, a private mechanic and now by the dealership.
Car specs:
- 06 Jetta TDI 5MT
- GIAC Tune/Chip
- No other engine mods
I have done a plethora of boost tests, vacuum tests, etc... Today, I got a diagnosis back from VW stating that I was overboosting. They suggested I have my chip removed and bring it back in.
Can someone look over this work order... it seems like they are saying that the measuring block is reporting a charge pressure of 2575 mbar. That is over 37 PSI!!! Is this the actual boost pressure?
What could be causing this huge boost spike?
Here is a pic of the work order and a link to one of my many threads on TDIclub.com:
