Audi A3 170 Back....but not completely Fixed

As some of you may have been aware i had my injector recall on my car about a month ago and when i got it back it had a the following issues :

• Shaky idle
• White smoke on start up ( Very toxic smell )
• Some loss in power in first few mins of running

Well am pleased to say i have got it back after 5days of Audi trying to sort the problem and the shaky idle seems to have gone to a degree. for some reason it creeps in for 10 secs now and then, then its gone again.

HOWEVER the Toxic smell still remains and when i first got it back i drove down the road to starbucks ( Caffeine lover) and as i reversed it into the car park space the smell was so strong it came into the cabin and me and my GF had to get out a thought a was going to sufficate!!! since then it has not been that strong but that cannot be right, and i have driven about 10miles since then to get home and even when its just idling on my drive the smell is still very potent and is there although no smoke once warm. Any ideas please to what this could be ?

Yes i am chuffed the shaky idle seems to have stopped, but the fact my car smells so bad all the time and is to me dangerously smelling fumes to be honest still means i am not completely happy and rightly so.

Could this be Turbo seals on the way out? To be honest it could be the smell of burning rubber such as seals.

Any Input at all would be really appreciated

Anyone?

Cheers for replies guys, Audi would of had it longer but as i am travelling back down south to work i needed it. I will be back in oxford after travelling from newcastle tommorow so i will get in touch with Oxford audi and tell them to have a look. I honestly think Audi did not test drive it nor did i ask to be fair. but the fumes and mean something and it needs sorted Asap!

Just to add its coming from the exhaust. But did come through the cabin that one time when i picked it up thats whats strange!
