My 2000 Audi A4 recently failed emissions with two codes: P1113 "Manufacturer Controlled Fuel and Air Metering" and P0343 "Camshaft Position Sensor 'A' Circuit High Bank 1 or Single Sensor".

I replaced the front 02 sensor and the cam position sensor and P0343 is no longer showing up, but P1113 is still there along with a new code P0411 "Air Injector Incorrect Flow".

I'm going to check all vacuum hoses for the P0411 before doing anything else, but I'm not sure where to go from here with code P1113. Any help or suggestions? I'm no mechanic but I can do basic work like this if it's nothing too involved.

Thanks for your help.

Whoops, I forgot to mention I've already driven the car through it's drive cycle and a few hundred miles beyond since replacing the cam position and 02 sensors.

Nothing? We sprayed all vacuum hoses last night to make sure there were no cracks or leaks causing the P0411 code but they all seem fine. Also checked the fuse in the black box driver's side near the wipers to make sure there wasn't a voltage issue but it's good.

Still unsure about how to deal with these two codes. I was told the downstream 02 sensor likely wouldn't be causing the P1113 code. Can anyone confirm?

Btw, the car is a 1.8T Quattro 5-speed, if that makes a difference.

Sounds more like an MAF code to me. Why was the O2 changed? Was it bad?

We were told it was bad and needed to be replaced by the mechanic who previously did work on the car, so when we saw the P1113 Air and Fuel Metering code when it failed emissions, we figured that was why. Didn't get rid of the code, though, so our bad for not checking the sensor itself.
