89 A4LD - Converter Clutch Override solenoid - Transmissions
AXOD Torque Converter Control solenoid circuit - Transmissions
Exhaust Heat Control (heat riser) solenoid circuit - Solenoids
84 EGR Vacuum Regulator - Solenoids
EGR cutoff solenoid - Solenoids
EGR Vent solenoid - Solenoids
33 ALL - (O, M) EGR did not open/ respond during test or if memory code, did not open intermittently - EVP EVR PFE
34 EVP - (R) EGR did not respond properly during test - EVP
EVR - (O, R, M) EVP sensor is/was high - EVR
PFE - (O, R, M) PFE sensor is/was out of range - PFE
29 Vehicle Speed Sensor problem - VSS
41 (R) System lean - Fuel control
(M) System was lean for 15 seconds or more (no HO2S switching) - Fuel control
yeah code 89 is transmission related for the a4ld (auto) tranny. do you think the computer was replaced or reprogramed?
also check your vacuum lines and make sure the EGR lines arent clogged and that the EGR opens freely that should take care of the EGR codes and you might have a bad o2 sensor considering that last code (41).
