    Alright everyone

    The motors running a bit rough on idle and my first thought was the EGR and i did a scan and found code 16825: evaporative emission control system.

    Im starting to think the EGR needs cleaned.

    Where exactly is it on the 1.8T???

    Theres a black plastic valve on the back of the engine near the bulkhead, is that it?

    Thanks for any help at all folks.

    Could it be that the boost gauge i fitted could be leaking air from the T piece? would this cause a rough idle?

    Thyanks again.
