Hi Jon, We reviewed your service file and our Service Department carried out, as per Audi’s requirements, an assessment of the situation, and concluded that the consumption level was within acceptable tolerances. As for the fuel injectors replacement, you noticed a malfunction signal which was attributed to two leaky fuel injectors (#1 and #3). As the vehicle was outside of warranty coverage, we installed ( with your consent) two after market fuel injectors ( Bosch brand). The difference in price for the after market parts was 60% cheaper, which translates into an overall saving of 30% on the final repair bill. Our work corrected the issue. If you need further understanding, please reach out to the General Manager, Francois Guimont at613-723-1221 or by email at fguimont@audiwestottawa.ca. Sincerely; Your Team at Audi West Ottawa
