I have a 2000 Audi A6 2.7T. I am getting the following codes from the system. The basic description of the code is posted too, but that doesn't tell me much.

18014- Rough Road Spec Engine Torque ABS-ECU Electrical Malfunction
17521- Bank1-Sensor1 Internal Resistance too High
17819- Sec.Air Inj.Sys.,Bank2 Flow too Flow
17831- Sec.Air Inj.Sys.,Bank1 Flow too Low

Can anyone elaborate what these codes mean. The check engine light will come on occasionaly. Also I do have the ABS light on and a flashing brake light on. These two lights usually come on after I have been driving a bit and will go out randomly and come back on. I not experiencing any performance problmes with the car.

Any help would be appreciated so I don't get screwed from the dealership. Also any repair estimates would be great if you kinda have an idea of whats going on.

Thanks!
