Hi Adman

Im not to sure should, i just know the faulty injector was replaced, is it normally changed when an injector is changed or is it an option extra when getting a new one fitted, all i know is that the performance isnt the same!!!

Thanks again

The reason I say is that, I have had a lumpy idle from cold since I have owned the car (40K AGO) and every time i took into to Audi they have said it is the injector seals....
