I've recently had a P2169 code showing up on 2.5T. Cleared it, and it's back in a day or so. :( This doesn't seem to be a very common code from what I'm seeing from google results which describe it as "Exhaust Pressure Regulator Vent Solenoid Control Circuit/Open" My scanner describes the code as something like 'O2S01 stuck full rich'. :confused:

The back (#2) sensor was recently replaced, but the front sensor is original equipment with 108K on the odometer. Should I dig around trying to find the source of this code or just throw a new front (#1) sensor at it?
