P1418 Faulty Fuel Level Sensor - Fuel Level Sensor harness is open or shorted - Fuel Level Sensor circuit poor electrical connection P1201 - Faulty Fuel Injector #1 - Fuel Injector #1 harness is open or shorted - Fuel Injector #1 circuit poor electrical connection P0265 - Dirty Fuel Injector 2 - Faulty Fuel Injector 2 - Plugged Fuel Injector 2 - Fuel injector 2 harness is open or shorted - Fuel injector 2 circuit poor electrical connection Personally I would put Seafoam through it and see if it helps. Usually Injectors need to be cleaned. Also, check your injector wiring for and pinched or frayed wires. I would then check the fuel pressure and if it is low then I would put a new fuel filter because it is still cheaper than a Fuel Pump.

I have the same problem. ESP, ABS and Parking Brake malfunction. When I went to pull the codes with a reader, nothing came up. I also checked the Enhanced DTC, and nothing there either. The parking brake does work fine. What could this mean? I have heard of reprogramming the main computer using Ross-Tech software. Could this be it?

For me it was the ABS module. I would recommend having a tech put a computer on the car to find the answer for you as it can be any number of things. They will be able to specifically tell you what the issue is.

I had my ABS module replaced and the wire harness for the fuel sender unit replaced, and shortly after I keep getting (intermittently) the rear brake, and signal light inop - like you have above. I thought this was a different issue, but maybe its related to the fuel harness being worked on.

I had a similar problem and got my ABS unit replaced. JTPAudi, I have the same problem where the rear right brake and signal light give an error sometimes. Do you why that is happening?

I have an A6 which had the ABS come on from time to time. When it came on the low oil pressure light and the low windshield washer fluid level also came on but there was no oil pressure or fluid problem. It could be that when the ABS light comes on several other warnings also come up. The fault is in the circuit board of the ABS unit. The solder on the circuit board needs re-doing. Mine cost me about $250 in New Zealand but I saw a guy in the US advertising the repair for about US$150. I found a youtube video on how to take it out and send away but it looked a bit technical so I just took it to an auto electrician and told him what the fault was and he did it all.

a6_er22s_2005 Audi a6 2005 3.2 ESP FAULT INDICATION LIGHT CAME ON AND HAS MY BABY DRIVING MESSED UP. I CANT ACCELERATE AND SHES RUMBLING REAL HARD WHEN I STOP AT LIGHT .. Did you ever figure the ESP problem out ??

the light on the dash with a cross trough it and all general lights and tail lights working means the third breaking light, a LED bar aswell in the sedan as in the avant has gone crooked. Probably one or two led's are down in the total bar. Check it by backing up in front of a shop or garage window. Replace(E-bay buy between 50 and 70 € or $ . LED bar remove instructions are on youtube under 3rd brake light etc etc
