Hi everyone. I've recently removed and replaced my Audio system with a non genuine one.(Tesla style) I have now changed it back to the original since changing it back I now have a red exclamation mark. Red p/s warning light. Amber abs warning light and amber Afs warning light. Also my gear selector will.not release when I push the brake pedal. I have to use the shift lock. I have also just changed the battery after it went dead. Apart from that it drives absolutely fine. Thanks Sam
