Default 2001 tdi with power issues

Hi my name is Paul, I own two tdi Jetta's a 2001 & a 2010 . I have owned diesel vw's since the 80's and enjoyed every one of them until know. I purchased the 2001 Jetta about 4 years ago with 170,000 miles. Up to a few months ago I had no problems. Then I had a issue with the trans not starting in low. Had a bad trans harness ,replaced same and fix the problem. Now I am having a problem with no power and check engine light lit. It seems to run fine until I hold pedal to floor for a while. Then it feels like it's starving for fuel. I have been on this web site using the information that was provided. When checked with auto store scanner a code 0234 shows up. It's very difficult to diagnose this problem when a few things give the same simptoms. Anyone have a similar problem?

0234 isn't a valid code but p0234 is for overboost. Sounds like you're getting limp mode: http://www.myturbodiesel.com/1000q/m...de-TDI-fix.htm

Read this and go through the checks. overboost can be caused by many things.
