Hi I'm Mitch. I drive a '98 A3 1.8T sport.
I went to have my car remapped yesterday but they couldn't do it as I had several fault codes. It's also turns out the previous owner has disabled the engine management light.
The codes are;
16500 - Engine Coolant Temp. Sensor (G62): implausible signal
P0116 - 35-10 - - - Intermittent
17978 - Engine Start Block by Immobilizer
P1570 - 35-10 - - - Intermittent
00561 - Mixture Adaptation
14-10 Adaption Limit (Add) Exceeded - Intermittent
16486 - Mass Air Flow Sensor (G70): Signal too Low
P0102 - 35-10 - - - Intermittent
01247 - Activated Charcoal Filter (EVAP) System Solenoid Valve 1 (N80)
26-10 - Output Open - Intermittent
The thing that has me confused is that I have no physical problems with the car. It's boosting between 8 - 9 PSI, it's not got any lag and the idle is fine.
Any advise into how to fix any of this is greatly appreciated.
( Sorry for the really long first post)
