Bring it to a local Pepboys (one by Keeler) or Advanced Auto Parts (on Clinton). They have a generic OBD II scanner that can read faults. I think you can even request for a print-out. Then you can go online to search/research the code.
There is an ECU Flash/update from VW for our model trucks that decreases the OČ sensitivity. It is an sissue with V6s...Ask the dealership.
