My 2005.5 Jetta isn't making much power right now it's got an EGR delete kit and tune it's also throwing the code PO299 (Underboost) when I get to and just above 2000 RPMs there is a loud clanking noise coming from the bay and I can't get my RPMs any higher although I can get the RPMs higher by holding in the clutch and having no load on the engine it will pass 2000 RPMs the clanking noise still occurs. I am pretty new to TDIs and didn't know if this was a normal sound or not and any help on what to test before I go and replace my turbo to save a little money would be helpful.
