    Very rough idle and emission light on 2.0 FSI

    Hi the other day my 03' 2.0 FSI A4 starting quite violently shaking when i was parked idling, it only does it under 1000 rpm soon as i press the accelerator the vibration stops, just quite worrying when i stop at lights etc,etc. Also the day after waht i thought was the engine management light came on, however after consulting the handbook realised its the exhaust/emissions light. Havent had time to take it to the garage yet and done about 600 miles since i noticed it with no ill effects....

    Anyone got any ideas as to what could be causing either of the problems? Id like to think theyre linked?

    Thanks in advance for any suggestions.

    Not sure, its only when the engine is warm and sitting at 800 revs,just feels like the engines rocking almost? As soon as i touch the accelerator or whilst driving its completely fine?

    Could be an air leak. Misfire should be present all the time

    Lift the cover off the top of the engine and check the oil breather hoses, very comon to have a split there where it plugs into the rocker cover where the pipe dissappears into the inlet manifold.
