2015 Audi Q7 engine problems

What owners report

• “Our 2015 Audi Q7 start using a lot of oil under 100,000 miles. Dealership replace turbocharger oil seals but that didn't fix the issue. The engine failed oil consumption test and was told the vehicle is safe to drive but will need to add oil every 1,000 miles. Engine failed three months later. Contact Audi of North American about the problem and ask about replacement engine because a vehicle of that type quality should not be having those type of issuea with low mileage.”

• “The car constantly needs to get oil. It is unreal that I went for a top off and the next day the oil light is on. The car has always been serviced by the dealer's service center, however no sense is made about this problem. The tail pipes show black that gives proof of oil burning no signs of oil leakage over the hood. I think this is a hazard that could only be after the damage is done. I have had to get oil put into the car thrice within the same week.”

• “The intake pipe between the intercooler and turbo consists of 2 pieces joined with 2 bolts. I was told by the Audi service tech that both of these bolts backed out and the pipe dislodged mid operation, disrupting air flow. Throttle was suddenly completely unresponsive and I was forced to coast to the shoulder of the highway with no throttle control. Link to video sent by service tech: https://app.quik.auto/j/356eeb5b”

• “PER AUDI DEALERSHIP AND FIDELITY WARRANTY, CLEANING OF THE SECONDARY AIR PORTS ARE NOT CONSIDERED ESSENTIAL ENOUGH TO BE COVERED BY THE EXTENDED WARRANTY. I WAS GIVEN THE REASONING THAT CLEANING IS NOT CONSIDERED A FAILURE OF PARTS; AND THEREFORE, DOES NOT MEET WARRANTY COVERAGE REQUIREMENTS, ALTHOUGH IT DOES ILLUMINATE THE CHECK ENGINE LIGHT AND IS DEEMED CRITICAL BY THE AUDI TECHNICIAN. *TR”
