Still have problem

My car is still hard starting after injector recall and also i have a very bad burning rubber/or something rich smell from the car.
But i have no coolant loss or milky oil so not a head gasket so what could this smell be coming from ?

This problems going on way too long now

Any help or advice appreciated people

cheers for your reply NHN , my car is still doing this so i will either go to a specialist to have a look or i will go back to audi AGAIN, and kick up some sort of fuss as this is a joke now. What i didnt mention from above as that its still shaking violently on idle and that needs sorting. None of this happened until injector recall or Cambelt change (done at same time) so basicly Audi have Broken a perfectly good running car at the time!
