P0021 and p0346 codes
Hello all....2007 audio a6 3.2 quattro...122k miles...here's my quandry: I have check engine light on..codes are p0021/p0021pending and p0346/p0346 pending....the engine runs great..no misses...same gas mileage as before..also...prnds is lit up red..however if I clear codes with vagcom, the prnds momentarily goes back to normal and then back to red...engine doesn't run as well as when the check engine light comes on...weird to say the least...could the codes be electrically related somehow ?...vagcom shows implausible signal...I can't figure this out...I'm hoping someone out there can shed some light on this
Thanks
Thanks
