    2011 Audi A4 EPC and MIL light on...some shaking going on

    Guest-only advertisement. Register or Log In now!
    The car first started having issues accelerating- felt like a lag. The MIL light blinked and then eventually stayed on. I changed the spark plugs and ignition coils. When I started the car up, it shook more and the EPC light came on. I let the car start up and warm up and then the EPC light came on. Does anyone have any idea what is going on? Or what may have caused these issues?

    maybe bad injectors or even cylinder heads. I'd prefer going to an Audi service.

    I do not have a scanner that could read the codes for this vehicle. I went to an Autozone but the scanner could not read the Audi.

    The Autozone scanners should be able to read our cars - you could also get an obd2 wifi/bluetooth dongle and use an app like dashcommand or carista to read fault codes. Even generic code readers should work. For us to help you we need the codes.
