I have a 2000A6 quattro 2.7l turbo. I read the following messages off the Obd2 reader:
P113, P1131 and P0741. The first two seem to tumble around the O2 sensor, the last one seems to be related to the torque converter. Can anyone give me some advice on what to do to get rid of these errors? meaning i want to fix the problem. How should i start trouble shooting. Does anyone know any more detail about one of the errors?
Thanks
Kai

 

I have seen the O2 sensors codes but the the tq one never and I would most concerned about that one. Does your tranny show signs of wear? hard shifting? Gears slipping? anything? How many miles?
I would suggest you search for that code and Audi, surely you'll find info frmo owners who've had that code... Google and forum searches will be your friend.
Also try and PM Auditech79.

 

The car has 105k miles. I have not noticed any problems with the transmission so far.
Since both first error indicate some sensor bank beeing to lean might it be a fuel filter problem that the motor does not get enough fuel?

 

Clear the codes and see what comes back...

 

I dont know p113 but i think u have it down. P1131 - Bank 2 - Sensor 1 Internal Resistance too high.
P0741 - Torque convt. clutch circ. performance or stuck off.

Here's the link

I actually have similar codes. P1136 & P1138.

 

Thanks that is actually a pretty good link to find the meaning behind the numbers. Now what i am more interested in is what should i do. I think clearing the code is a good start. But can someone give me a hint or any direction in what to replace? What is a Bank1 and 2 Sensor2 sounds a little bit like Star Trek ;-)

 

I found out what the P1113 and the P1131 error is. It means that i have to replace the two upstreamoxygen sensors. The errors mean Bank one and two sensor 1 internal resistance too high. So lets see what happens if i replace them.
I am still chasing down my P0741 but i am pretty sure i can figure it out using the following link. At least there is some hope that it is just a low trani fluid:
