Car is an 05 2.0 tfsi Quattro s line. Had an emissions light coming on recently which my mate diagnosed as a vacuum leak using his vagcom. Anyway, took it to Audi for coilpack recall and they said the problem is the charcoal canister. I paid to have it replaced and to be fair it seems like the problems sorted as the light hasn't returned. Only thing is I don't think they have changed the canister. Is it a 100mm diameter black square box around the front left of the engine bay as that's what I thought was the canister but it looks like it's been there for years. I would expect a new one to be shiny. The bill also showed a hose and a couple of clips so I'm just thinking maybe it just needed a new hose and they have charged me for the canister anyway?
Just want to be sure before I ring audi.
