    Well after working under the metal bracket today looking into how to attempt the N248 removal I came a accross something new that I never knew before and as thread title states it is the N211 valve.

    Now I can clearly see it has a 'dial' on it and I have read that is has something to do with the cold starts and vaccums. By twisting the dial what exactly does this achieve because I think I accidentally turned it today when working on the car. I don't know which was I turned it but as far as I know I did.

    Cheers guys!

    Its N112 and N249 btw...

    Altering the screw on the top changes the way the valve operates and can damage it... it's not advised to play with the setting
