hi, am new here and had questions to audi a3 1. I bought an audio a3 diesel 90 ps bj 2000 and wanted to have more ps but what can you recommend there doesn’t have to be much thought about 20 ps more. 2. what does it look like with sound, colleague told me there’s nothing there, because it’s diesel but I think something you have to be able to do just because the diesel has no or bad sopund or? P.S. one knows the codes for the climatetronic where you can see how much you just verb and so. thank you.
