Car is a 2002 Jettta 1.9TDI (not the 1.8T Beetle)
I have a code P0234 Turbocharger overboost condition. I checked my wastegate bypass valve for supplied voltage and it was good. Then I used jumpers to try and activate the solinod, nothing happened so I replaced the valve. PN 1J0 906 627 A if there is any question as to which valve I am talking about. I reset the MIL and drove the car, once it went through it 0BDII checks it reset the MIL for the same P0234. Where should I go from here? Is there a common problem that sets this code?
Thanks in advance,
