knocking/ Clunking on start up.

    Hey guys,

    okay so the engine/emissions light came on the other day, up until then it was perfectly fine! So now the light has gone off however, now when I start the car there is a bit of a bang and a few less vigorous bangs afterwards for a short period then all is fine?!!?

    It sounds like the same problem as this http://www.audi-sport.net/vb/a3-s3-sportback-8p-chassis/190496-engine-knocking-start-up-help.html if it helps?

    I've not had diagnostics however I have a sneaking suspicion that it may have something to do with the intake manifold flap,would this cause this problem, it could be the cause for the emissions light??

    oh and its a 2004 a3 2.0tdi BKD engine

    any help would be appreciated.

    thanks, Ben
