I recently had a local mechanic replace my front brake pads and rotors on my 2001 Audi A4. He did not reset my ECU and my brake pad and brake fluid lights are still coming on and also beeping. After the replacement, the front left turning signal is lighting up when I apply the brakes. Also, anytime I have my lights on the cruise is not working, but works completely fine with the lights turned off. Do I need to have the system reset and is there a possibility that there was damage done to the brake sensors during installation? Any help would be greatly appreciated!
