Hi there guys I have and Audi A3 2.0 Tdi (140BHP) on an 03 plate so the Mk 2 and whilst driving long distance yesterday it went into limp mode and the engine management light came one.. im going to take it to a garage tomorrow but I wandered if anyone on here had any idea why it woud do that? also I switched it on earlier to move my car out of the way of my dads and it pissed out blue smoke (only time its done that though). Also on tick over the engine seems like its missing a beat a bit..Misfire seems like a strong word but a very tame version of it. If anyone has any ideas or advice I would be massively grateful!

James
