I have a 99 A6 2.8 30v 220k AT Quattro.
I started the car yesterday and it would not stay running until I tapped the gas peddle and feathered it, then it would idle at about 250-300 rpm. No power under acceleration, and will not go over 30 mph.
I ran the codes and it came up with 3;
1. Throttle position Sensor
2. o2 bank 1
3. o2 bank 2
I understand that the TPS is not replaceable, that you are just better of buying a used throttle body. But a lot of the time it can be some other outlying problem.
I do not have a vagcom available to me at this point in time either.
Any input will be helpful
