I have been having quite a few problems recently with oil and water leaks and the car stuttering above 2,000 rpm so i thought that i would try to run some diagnostics on it and i got these codes.
FYI, my a2 is a 1.4 2004 TDi (75).

Does anyone know what that could mean and how to fix them?

Thanks for all of your help.

I'd say your misfiring is probably due to an injector wiring harness - these are known to fail on the TDi and give misfire symptoms which the ECU reports as an injector fault. Get the harness changed first (the part is about £70 and it's a 2hour job) and see where that takes you.

The ESP fault - I'm not sure, but perhaps the ABS wheel speed sensor is faulty? There are issues with the wiring harness getting damaged. Again can be replaced by replacing the wiring.

The airbag wiring fault - do you get an airbag warning light on the dash? I know nothing about airbags but perhaps there's a dirty connection in the steering column wiring? Take care on that.

Thanks, in regards to injector wiring. Is that something that I would be able to do myself (i have managed to change a coolant temp sender and break light switch) or should I just take it to a garage and tell them what i want done?

So would this be fixed by sorting out the first thing?

I guess that this is something that should be done at a garage, should i take it to the Audi garage or just a normal place?

Thanks

The injector wiring harness you can do yourself although it's a bit of a fiddly job as you have to remove things like the windscreen wiper arm, the air intake duct and various other bits, plus access to the bolts at the back on the top of the rocker cover is limited. A competent mechanic can do the job in under 2 hours.

The ESP/ABS sensor is completely unrelated. This is a wiring loom that runs down the suspension to the wheel hub. The cabling can get damaged, or the sensor itself in the hub can get damaged.
