Hi there
thanks for taking your time on my first post
VW Golf 2003 TDI 1.9l ALH 151k miles
Engine died whilst driving. Couldn't start, P0251 code
Changed fuel filter, checked Fuel cutoff valve OK, purged fuel lines, and got it to start, but running at very low idle and no response on the throttle. no obvious smoke
Unfortunately don't have any of the VW diagnostic tools, just the OBD scanner, and P0251 seems to be a catchall code that covers a lot.
Any suggestions on the likely cause, or is the only reasonable next step to get a proper diagnostic tool for the ECM? Or any suggestions on how to diagnose further using a generic OBD scanner?
Wanted to ask before ripping out and replacing the throttle position sensor (also the idle speed is very low) or spending a lot on a special scanner.
thanks!!!!
