If you ever get the above-mentioned code after you have done a diagnostic test, and you don’t know where the power relay is, go to where the ECU is. The Audi’s ECU in SA is situated under the bonnet on the right-hand side in the engine bay. The number on the relay is no 30. The problem with this car was that the engine would cut out sometimes completely and would not start again. The engine will only start after a few minutes. This specific relay was getting very hot in a short time. Replace it and your problem is solved. This car was at the agents for their 20 point test, but they could not find the problem.
