    Hi Guys

    I had an issue with hard starting a month ago and decided to change the glow plugs after an error on the Vag-Com and while doing that I cleaned the EGR valve.
    Since cleaning the EGR and doing the glow plugs I have had an issue with rough idle when the motor is cold till reaching operating temperature.
    There is what seems like a misfire at low speed when cold.
    I decided to change the EGR and still no luck.

    I've read that it could be the glow plug/injector harness but wanted to check before ordering one.
    Hopefully you guys can give me some pointers.

    Thank you
    Frans

    What error codes are you getting with VAG-COM?
