    "I recently ordered this fuel tank cap for my 04 A6, which had the MIL light staying on. The A6 had been recently serviced by Brahman so I figured the problem was not a serious one. The fuel cap arrived within 2 days. It bore a very close resemblance to the original and it solved my problem.The MIL light did not go out immediately, so I called Audi and was advised that it would take 5 to 10 starts from cold for it to readjust and it did disappear within 2 days. Needless to say I am very satisfied with this product and would highly recommend it. Tony."
