A lit-up MIL or malfunction indicator lamp could mean anything from a malfunctioning or loose gas cap to a failing exhaust system. If your Audi A5 MIL is on, have it checked out immediately. If it is flashing, have your car towed to a nearby car service center so that the reason behind it can be diagnosed and repaired on time.<br />https://manfredsimportauto.com/<br />
