What do these error codes mean when I clear them and they don't come back? Nothing seems to be strange about my car and on the way home, I noticed my SES light on. I hook up HPTuner and found out the following....
P0135 - HO2S Heater Performance Bank 1 Sensor 1 (OLD) (Immature)
P0155 - HO2S Heater Performance Bank 2 Sensor 1 (OLD) (Immature)
P0336 - Crankshaft Position (CKP) Sensor A Performance (OLD) (Immature)
P0751 - 1-2 Shift Solenoid Valve Performance - No First or Fourth Gear (SES) (OLD) (History) (Current) (Immature)
What do these codes mean when I clear them and they don't come back on.....well at least so far as for 10 miles or better when I got back home from test driving it to see if they would come back???? Is this something serious or just a freak of nature that happens every once in a while???? The car drives perfectly normal without the A4 acting up. As for the CKP and H02S???? I just don't know.
