Filed Oct 7, 2026 · Engine · VA

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.

Warranty will be over in 60 days; the Catalyst Coverter is going back, the Audi dealer and Audi Corporate are delaying the fixture do to some mis communication between dealer and corporate. The problem has to do with DEF gases not being cleanup. The error code is P20EE00 and the engine light is on. The part is under warranty and Audi Corporate is delaying the fixt because the do not wish to pay for the cost. They have had my vehicle for a full week and no decision when to replace the part. I strongly believe they want the warranty to expire so the customer has to pay for cost of the catalyst. The dealer has verified that part is under warranty but corporate does NOT response to the dealer.0

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.

I am writing to report a problem with Faulty electronic control monitors (ECM). This is a vehicle safety problem, because if the ECM is faulty, drivers won't know when there is truly a problem. Approximately 2 weeks ago, my vehicle check engine light came on. I don't drive the car that often, so I scheduled an appointment and took a picture. The day of my appointment the light wasn't on. The report number 251149 shows a diagnosis of a faulty ECM. I believe there is a problem with the manufacturing, because my car is a 2015 and report numbers 185124 and 180866 also reflect faulty information and electronic control monitors. This shouldn't happen in a car that is ~6 years old and has only 50,000 miles.

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.

5 times in the last 6 months the "glow plug" indicator light has come on and the vehicle experienced a loss of power. Twice the car completely broke down, twice audi could not replicate the error code, the last time this happened I had just picked up the car from audi after it was repaired. The glow plug light came on and it went into "limp mode" where I experienced a loss of power as I was getting on the freeway, almost got hit as I couldn't accelerate past 35 MPH.
