One day the low oil light came on, brought it to carousol Audi in golden valley mn and they informed me about the oil sludge problem and told me to get my oil receipts ready. I changed my own oil and don't have my oil receipts and am now being denied a warranty coverage. Was told that I would have a new engine put in if I had oil receipts but will cost at least 9000 without the warranty.

I purchased certified pre owned car from dealership-Audi A4 3. 0 quattro, 2005. 2 days later I could not pass required state inspection due to "check engine" issue-misfire on a 6th cylinder. I brought the car back to dealership a few days later to correct the problem. The problem was corrected temporarily and car passed the inspection-check engine light was reset by dealership. A few months later "check engine" issue came back after scheduled maintenance (at 50,000 miles) was done by authorized dealership. Problem was temporarily corrected 2nd time. In December 2008 after 3rd time "check engine" issue, dealership proposed to replace whole engine in order to resolve this issue, which was done. On February 11, 2009 driving back home from work I've noticed an exhaust gas smell inside the car, car was shaking and "check engine " light was "on"/not steady. I contacted Audi customer service advocates to report the problem and start the case. I brought the car back to dealership for repair 4th time. They performed necessary steps to correct the problem but failed (2 sensors were replaced according to them and "check engine" light still "on"). I was informed that dealership did not replace the whole engine back in December 2008 - they only replaced lower part of the engine knowing that there was a problem with misfire on 6th cylinder (upper part of the engine). After 3 weeks of waiting and constant repairs I am not sure that this problem has been corrected permanently. Facts: car was purchased at 49,000 miles on April 29, 2008. My car has been at dealership for 75-80 days out of 10 months since I purchased it. Total mileage as of February 28, 2009 is 52,450.

My 2002 Audi A4 just hit 69,900 miles & the 3rd turbo on my car has just gone bad & has now developed a ticking noise in the valve-train. Fiore Audi in altoona, PA looked at the car & said they never heard a noise in the top of the motor & that the "dentist drill" turbo noise was caused by an exhaust leak. I verbalized my concerns over oil sludge issues with this car & they pulled the valve-cover & oil pan & found oil sludge build-up in the oil lines feeding the turbo & in some of the oil galleys in the engine. Audi of America agreed to replace the turbo and the oil feed lines under Audi's extended oil sludge warranty. After the engine was put back together, fiore finally heard the "ticking" noise in the top of the motor. After pulling the head they determined that the engine block and the cylinder head were warped. Fiore technicians informed me that these damages were caused by the engine being excessively overheated. The car had never indicated that it had overheated, yet for this "excuse/reason", they refused to cover any repairs regardless of the fact that I had produced receipts documenting that the oil was changed religiously around 3,000 mile intervals (well below Audi's initial recommendation that the oil be changed every 10,000 miles, as referenced in the manual, or their subsequent recommendation of changing it every 5,000 miles) with an Audi recommended full synthetic oil as per the sludge warranty policy. The oil lines that feed the turbo charger were never checked or replaced during any of the turbo charger replacements, or other oil smoke complaints, until now. After our 3rd turbo replacement, obviously due to oil sludge build-up, I'm now told my motor is no good. Had Audi taken care of this issue when these problems were first developed & identified, it wouldn't need a new engine at less than 70k miles due to an issue that is well-known with this vehicle & that was also obviously present when this vehicles warranty was in full effect.
