Hope you find a solution. Out of curiosity did you buy your tdi in York, PA? I was looking at one up there similar to what you described.New owner of a 2003 Jetta TDI 5 sp wagon. New forum member.
Few days ago started seeing the Instrument Cluster intermittently die then come back. Then the whole car died. Batter at 2.94V, replaced 6 yr old battery. Now things back to normal until I get to about 1000 RPM and the IC dies again. Running with traffic about 50 MPH and put in neutral and let RPM's drop and cluster comes alive Tach says 900 RPM on engine 42 MPH on Speedo - till I let out the clutch and RPMs go over 1000 and it dies again.
I've wandered around here for the past week or so, but haven't seen anything like this. If I say "Pretty Please" can someone point me in the right direction?
