    Hello people

    Twice now my engine management light has come on whilst on a sustained period of time on the motorway. I don’t go above 80 as you get blown everywhere.ha. 70-80 mph. I was driving from Bristol to Taunton so not that long on a motorway, 5 junctions. Both times the engine management light came on Whilst on the motorway. After a couple of heat cycles it’s gone away. Has this happened to anyone else? The performance doesn’t change, it was fully serviced at the beginning of august. Are they just not made for constant motorway riding?

    Have you checked to see if there is a fault code in your system?

    Checking fault codes:
    • Hold “I” button and turn ignition switch to ON.
    • Release I button when “DTC” appears on the left window.
    • Read the code. It'll be a P followed by four digits.
    • P0000 is no codes

    Have you checked for stored DTCs?

    Sorry. I hate acronyms too!

    Fault codes. If the error light is on there should be fault codes stored. You can get them yourself and look up the values on the web.

    The steps are:
    Hold the "i" button on the left
    Turn the key on while holding "i" button
    The display should cycle through to DTC, release the "i" button.
    It should show the codes.

    Good luck.

    I have tuneecu, but you don't need anything to display the codes. Just follow the steps (I think I have them all in order)

    For a code reader you could try one of these below.
    I switched my 765 on with the tank removed and it put the EML on. This soon sorted it.

    Readers with leads are ok with earlier bikes but don't work on later stuff as it has to be by Bluetooth.
    Can someone confirm the reverse isnt so meaning you can use Bluetooth on older models?

    On later stuff you also need to balance throttle bodies by electronic readings hence why I bought it initially.
