2025 Audi SQ5 Lemon Law Case Study — Virginia
A Nearly New 2025 Audi SQ5 With a Check Engine Light That Kept Returning
Our client purchased a 2025 Audi SQ5 in Virginia. With only 733 miles on the odometer — essentially a brand-new vehicle — the SUV developed a recurring check engine light that brought it back to authorized service across multiple documented repair visits. What began as a single warning escalated into a string of stored fault codes pointing at the vehicle's electrical control system.
According to the repair documentation, the dealer first found the battery at 54% voltage, charged it, and cleared the faults. The check engine light returned, and a later diagnostic scan turned up 110 stored codes — including a communication loss with the J519 vehicle electrical system control module and immobilizer/key adaptation errors. Even after the module was restarted and the driver-assistance systems were recalibrated, the warning lights came back, this time accompanied by a forward collision warning on the dash. After this pattern of unresolved electrical faults on a nearly new vehicle, our client contacted Easy Lemon for legal assistance.
What Went Wrong
- Recurring check engine light: The primary complaint was a check engine light that returned after each repair attempt, beginning when the vehicle was nearly new.
- 110 stored fault codes: A diagnostic scan found 110 stored codes, including a communication loss with the J519 vehicle electrical system control module.
- Immobilizer/key adaptation errors: The diagnostic also surfaced immobilizer and key adaptation errors, which the dealer addressed by adapting the available key and restarting the J519 module.
- Driver-assistance and forward collision warning: Driver-assist modules showed no calibration and required an ADAS calibration; a later visit reported the check engine light together with a forward collision warning on the dash.
Documented Repair Visits Could Not Permanently Fix This SQ5
December 12–30, 2025 — Check Engine Light On
The customer reported the check engine light was on. The dealer found battery voltage at 54%, charged the battery to 100%, cleared the faults, and verified vehicle performance. No further issues were noted at that time.
January 22–February 5, 2026 — 110 Stored Codes and Module Communication Loss
The check engine light returned. A diagnostic scan found 110 stored codes, including communication loss with the J519 vehicle electrical system control module and immobilizer/key adaptation errors. The dealer adapted the only available key to the vehicle and restarted the J519 module. Driver-assist modules showed no calibration, so the dealer performed an ADAS calibration due to a KD02 update failure. After calibration, the vehicle was test-driven for 53 miles with no failures or check engine lights observed.
February 21, 2026 – Present — Check Engine Light and Forward Collision Warning
The customer reported the check engine light and a forward collision warning on the dash. The dealer performed an initial evaluation of the recurring concern.
Vehicle Buyback Secured
