2017 Audi Q7 electrical problems

Filed Sep 5, 2026 · Electrical · CA

The vehicle has a recurring electrical failure involving the camshaft position sensor circuit (DTC P0365). The sensor itself is functional, but the wiring harness leading to the sensor develops internal copper fatigue due to a design flaw in the factory routing. The harness is bent tightly behind the passenger-side cylinder head, causing vibration-induced internal wire breakage that is invisible externally. This failure is well known to Audi dealers and has been reproduced and confirmed by multiple service centers. The problem is not caused by the sensor, plug, or engine components. It is caused by the wiring harness design, which repeatedly fails in the same 6–10 inch section. The defect causes intermittent loss of camshaft signal, illumination of the check engine light, and inability to pass emissions. Repair requires cutting open the harness and splicing in new wire, costing approximately $700–$1,200 each time. This is a repeated electrical defect caused by poor harness routing and inadequate wire durability. This issue affects safety indirectly because the vehicle cannot reliably report camshaft position to the ECM, and the failure is unpredictable. The defect is widespread among vehicles using the same engine and harness design.

My 2017 Audi Q7 with the 3.0T engine has experienced repeated engine/ignition system failures. The vehicle displays a "System Malfunction" warning light accompanied by shaking and stalling. This same malfunction has occurred at least 3 separate times over the past few years. Each time, a repair shop diagnosed and replaced faulty ignition coils, and the vehicle ran normally for a period of time before the identical malfunction returned. The vehicle is currently inoperable due to the most recent occurrence. This creates a safety risk because the stalling and shaking can occur while driving, with no clear warning beyond the malfunction light appearing at the same time as the symptoms begin. A stall or loss of power while in motion, especially in traffic or on a highway, could lead to a collision. The problem has been confirmed and repaired multiple times by an independent European auto repair specialist, who stated this is a known, recurring issue with this engine/model. The vehicle has not yet been inspected by the manufacturer directly. Separately, the vehicle has also developed excessive oil consumption, requiring approximately 2 gallons of oil added roughly every 6 weeks, with the frequency increasing over the last 2 months. I am uncertain whether the oil consumption and the recurring coil/ignition failures share a common root cause, but both issues are ongoing and unresolved. The vehicle and its components are available for inspection upon request.

Getting error message that the "Front Left Side Marker Light Defective". The light appears to be operational. Service shop looked to read the errors with ODB2 and both light modules (left and right) are not communicating any info. In same time the warning in dashboard is continuous and can impede gauges visibility during night. Audible warning noise can also activate at random times. Searched for this issue and Audi recalled some models for electrical software issue but many users outside the current recall report this same issue. Please expand the VIN numbers for the recall action for safety.

The car caught fire and burnt to to the frame. The message that came on the dash board before it caught fire was camera. I told Audi and they disregard all of that. They told me they were going to check or do investigation and the only thing I was told after looking for answer was this!

My vehicle is experiencing the same issues as described in the federal safety agency Campaign Number: 16V642000, but my vin number isn't listed in the vehicles affected even thought the year make and model agree to the recall. Should the dealer be willing to correct this issue since it's a known safety hazard?

Front left and right marker lights show up as defective on the dashboard, intermittently, but the lights are working. Have seen on different forums that this is not uncommon with this vehicle. Many complaints. Tried working with Audi/USA and have followed their advice with needing a dealership assessments. I have done this on two occasions, but they said that they will not be responsible, but that the dealership will offer a labor discount of 10%. These quotes are over $7000 to replace the lights and modules (that are working), if you don’t want to keep listening to the dinging warning bells. And it forces the customer to fix it because you will never be able to sell the car even though the lights are working. Think at least Audi should pay for the parts on all complaints. There is such a term as “good will” and they should broaden the recall on this item. My vehicle had a recall on this that the dealership repaired before I even purchased the vehicle which was NEW. Audi informed them when it was on the lot, but they say it was for the same thing but they just had to do an update on it? How did they know that when the car only had maybe 10 miles on it when we took delivery. Hopefully, someone in your department has some clout and back Audi up against the wall and take responsibility.
