2001 S4 Problems 124,000
I am having a couple issues with my 2001 Audi S4
Just replaced the cat convertors and all four O2 sensors.
I am getting the following codes:
P1131 - bank1 sensor1 - internal resistance is too high
P1113 - bank2 sensor1 - internal resistance is too high
what causes these codes? I did not use Bosch sensors but half price ones.
I would think they would work. Code comes on everyday.
When I drive and reach a certain speed the ABS and that rotation lights come on and the car drives funny. I think these two issues are related somehow.

Put Bosche O2 sensors in the upstream and erased all the codes with my scan tool. I test drove the car for 20 minutes and no codes came back. I hope it was those ****ty O2 sensors that were messing everything up! Will post more in the next couple days.

Now I have codes P1127 and P1129, both banks running rich.
Also car is having big problems starting. It won't start this morning. It starts up and then dies right away.
Anyone know what is causing this?

The secondary O2 sensors are also able to affect the reported AFR. If they are reading incorrectly that might be causing the ECU to run rich.
Possibly try disconnecting the secondary o2 sensors, clear the codes and see what happens. You'll probably throw a cat efficiency fault code, but it might give you another data point for what might be affecting things.

If so it's the immobiliser.
In 2001 the immobiliser will be incorporated into the dash cluster.
Transponder in the key is energised by a coil in the black plastic ring around the ignition barrel. Only fix for your car I can think of is to unplug and plug-in the coil to ensure it is working correctly. Also, make sure key is fully home in ignition barrel and the housing of the key is as close as possible to the plastic ring around the barrel.
Turn ignition on and wait for yellow key/car symbol in Tacho to disappear before starting.
If your car main battery is a bit suspect, this can affect the immobiliser. I had issues both on my A4 and S8, which were a little bit frustrating until in both cases the battery died a short while later.
(do not confuse the transponder with the remote central locking - completely different things on these cars and is not affected by low batteries in the remote)

Thanks I have a new battery in the car....took it to the dealership they said that the spark plugs were fouled and there is carbon buildup in the engine.
The rape has begun $200 to look the car over and $525 to change the spark plugs and clean the carbon, i was told $400 of this is labor....also told I have other issues with the suspension and clutch and tons of DTC failure codes ughhhhhhhhhhhh

Good guess no I do not have this flashing light......no battery in the key
Sounds like classic immobiliser to me - do you have a flashing yellow symbol that looks like a 'key in the back of a car' flashing in the Tacho when it starts and dies?
