check engine light went on, i used snap on OBDII computer to check for the code, got number P1165 (undocumented error code) on a 2001 Golf GTI GLX VR6, does anyone know of this code or where i can look up this code online, thnx
agiht i did a little homework, found the code
Bank1, Long Term Fuel Trim, Range 1 Rich Limit Exceeded
this could explain my fuel probrems, car has been eating gas like crazy.
anyone have any ideas???
Looks like your engine is running rich, enough so that it's past a pre-set limit to warn you that something is wrong.
It could be due to a number of things. Here's a few that the Bentley lists.
- bad MAF
- bad O2 sensor
- fuel injector(s) leaking
- fuel pressure too high
- evaporative emission (EVAP) canister purge regulator valve -N80- permanently open.
My guess is it's one of the first two.
