Component/System: Engine and Cooling - Water Pump / Coolant System Vehicle: 2021 Audi SQ5 Engine Code: CWGD Mileage at Failure: 71,000 Date of Incident: 8/6/2025 Audi Denver I'm reporting a known defect affecting my 2021 Audi SQ5 with engine code CWGD. The engine experienced an internal coolant leak from the water pump housing, which is a known issue previously acknowledged by Audi in TSB #19Q5 2022 01, covering earlier 3.0T engines (DEWA/DEWC). Although my engine (CWGD) is not listed in the bulletin, the failure is identical in nature: the plastic thermostat/water pump housing fails internally, leading to coolant loss and potential engine overheating. This issue is widespread among Audi 3.0T engines, including CWGD, and poses a risk of engine failure and overheating. …
Electrical system
While driving at normal operational speeds, the vehicle suffered a sudden, un-commanded, and catastrophic loss of motive power while navigating a live traffic intersection. The transmission completely disengaged all gears without warning, rendering the vehicle entirely stationary and immobilized in the path of oncoming traffic. This failure created an immediate, severe safety hazard, exposing the occupants to a high risk of a side-impact or rear-end collision due to the inability to clear the intersection under the vehicle's own power. The vehicle had to be flatbedded to an authorized dealer (Audi - Glenwood Springs). The professional diagnostic evaluation confirmed an internal failure of the transmission assembly and Transmission Control Module (TCM) / Mechatronic unit, requiring a total replacement of the powertrain assembly. The failure occurred at 59,000 miles.
Comfort Module J393 failed that is tied to all electronics warnings in car. brake warnings, light warning, security warnings, etc. Car was unable to be started as a result. If these electronics failed during driving, its very dangerous and could force crashing of vehicle. According to Dealership, failed module was submerged (ie water flooeded). This is a self contained electronics module that is not exposed to elements. The car was parked in driveway. it rained lightly over the weekend. Then this occurred. the damage and replacement cost was over $10K in damage. Audi dealership stated replacing rear water drain may be kinked or damaged causing water to leak where module located. Its not normal for self contained electronics modules to have this problem.
