2017 Audi Q7 electrical system problems

“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…”

“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…”

“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.”

“I am having issues with my vehicle ( Audi 2017 Q7)that matches Audi Recall 97CB NHTSA campaign Number 16V642000 regarding the side marker light software malfunction. While my VIN is not currently showing as open on a Recall my vehicle is experiencing the marker lights failure. My vehicles MFD date is 05/16 which is in the dates of the recall 97CB but is for some reason excluded from the recall. I have had the vehicle at the Audi dealer to check on the problem. They have had the vehicle two different times totaling 15 hours and are unable to find a problem.They refuse to provide the recall remedy because my VIN is not currently flagged. my Vin is [XXX] . I am requesting my VIN be added to the 97CB NHTSA# 16V64200 My case # with Audi is XXX Rep is Susan .”

“The contact owns a 2017 Audi Q7. The contact stated that while driving at an undisclosed speed, the driver's side marker warning light illuminated. The vehicle was taken to an independent mechanic with a failing driver's side marker. The contact was informed that the driver's side marker needed to be replaced. The vehicle was not repaired. In addition, the contact stated that while driving at night, the failure was a safety issue. In addition, the contact stated that the dinging from the sensor was a distraction. The manufacturer was made aware of the failure, and a case was filed. The contact referenced NHTSA Campaign Number: 16V642000 (Electrical System, Exterior Lighting); however, the VIN was not included in the recall. The contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was approximately 96,000.”

“The contact owns a 2017 Audi Q7. The contact stated that while driving at an undisclosed speed, the message "Side Marker light Fault Detected" was displayed. The contact stated that after a visual inspection, the contact became aware that both side marker lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the side marker light assembly. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 16V642000 (Electrical System, Exterior Lighting); but the VIN was not included.
