Hi guys,

I've a '99 Audi 1.8T Quattro that I got a few years back. Lately, the car has been experiencing a number of problems. The check system light on the car had been on for a while, but since I drive the car quite infrequently, it didn't matter much. My mechanic has told me that the engine requires a new O2 meter, and once that is in place, the issues I have been having will be fixed. The main problem is that when I am driving, the car seems to splutter, sometimes while taking a turn the engine has also gone cold dead - the issue seems to be with the fuel injection which is unstable and sometimes that causes problems.

Do you guys have any inputs based on the following information (error codes from the central computer) -->

P1425 Tank Ventilation Valve - Short to Ground A
P1472 Emission control circuit short
P0102 Airflow voltage signla too low
P1196 O2 sensor heater circuit
B1S1.P0134 No O2 sensor activity
B1S1.P1198 O2 heater circuit B1S2

Thanks a lot in advance,

Regards -

Raj.
