Hey there. This vehicle has air bag system active head restraints. Cutting the wires caused the air bag system to set codes for the head rests and disable the complete air bag system. You will need to replace the head...

As you may know, the traction control system monitors the steering stability of the vehicle and engages when loss of traction has been detected. This is done by the use of electronic sensors that communicate with the Power Train Control...

Good question and you are correct. It sounds like it is your power steering pump. There is only one noise a bad power steering pump makes, and no other part will make the same grinding noise as the power steering...

It is not likely the brakes are causing the Powertrain light to come on unless you have brakes that are grinding metal to metal. This can cause excessive metal to get on the wheels antilock speed sensor and cause erratic...

With most any other vehicle, your diagnosis would be dead on, congratulations! In your case, the problem is most likely the thermostat. With this Audi engine, the Audi engineers were more clever, there is only a single coolant temperature sensor,...

Often times when the ignition is replaced the security system will need to reprogrammed to recognize that a component has been legitimately replaced and that the vehicle is not being stolen. I would ask one of the mechanics at YourMechanic...

Among the possibilities are faults in the throttle position sensor, mass airflow sensor, vacuum leaks, a clogged fuel filter, defective EGR valve or control circuit, and worn out spark plugs and wires. A mechanic would simply investigate these possibilities sequentially...
