Body & exterior
Safety recall published2018, 2019Loose rear wheel-arch trim
A protruding rear wheel-arch cover or fresh wind noise can signal the loose trim addressed by Audi recall 66K8.
Audi recalled certain 2018 to 2019 SQ5 vehicles because the rear wheel-arch cover trim could loosen and detach while driving. The detached trim could become a road hazard. Recall status is VIN specific even when the model and year match.
Symptoms to compare
- The edge of a rear wheel-arch cover protrudes from the body
- Wind or fluttering noise comes from the rear wheel area
- A wheel-arch trim panel feels visibly displaced
Other ways owners describe it: fender flare coming loose; plastic trim sticking out by rear wheel; wheel arch cover flapping; new wind noise from rear wheel; body trim falling off Audi.
Which vehicles the source covers
- Certain 2018 to 2019 Audi SQ5 vehicles
- Recall 66K8 eligibility must be checked by VIN
Safety recall eligibility is determined by VIN, not by mileage or visible wear alone.
Published recall remedy
Audi's recall remedy is to replace the four clips securing the forward part of the rear wheel-arch trim with revised clips.

Check the VIN for recall 66K8. An authorized Audi dealer replaces the four specified retaining clips when the vehicle is included.
Look for a lifted edge while parkedSimple visual check · 3 minutes
With the vehicle parked, visually compare the rear arch covers on both sides and photograph any edge that is standing away from the body.
Limit: Do not pull on the trim or try to secure recall parts with tape for road use.

Electrical & software
Official safety recall2018, 2019, 2020, 2021, 2022Campaign 21V947000Electrical or software fault may disable vehicle functions
A liquid spill in the rear seat, or water ingress from an insufficient body seam underneath the vehicle may allow liquid to penetrate the gateway control module, causing it to shutdown.
NHTSA campaign 21V947000 includes certain 2018 to 2022 Audi SQ5 vehicles. Volkswagen Group of America, Inc. (Audi) is recalling certain 2021-2022 Q5 Sportback, SQ5 Sportback, 2018-2022 Q5, and SQ5 vehicles. A gateway control module shutdown will suddenly reduce engine power, increasing the risk of a crash.
Symptoms to compare
- Warning messages, a blank display, a no-start condition or loss of a vehicle function may occur
- An open campaign appears when the complete VIN is checked
- Some recalled vehicles may show no advance warning before the component fails
Other ways owners describe it: dashboard lit up with warnings; car electronics stopped working; screen keeps rebooting; car will not start after update; electrical problem with no warning; software recall.
Which vehicles the source covers
- 2018 to 2022 Audi SQ5
- NHTSA campaign 21V947000
- The manufacturer filing lists 288,991 potentially affected units across the complete campaign.
- VIN eligibility determines whether this recall applies to an individual vehicle
Safety recall eligibility is based on the VIN and campaign scope, not ordinary warranty mileage. Check the complete VIN even when the vehicle is outside its original warranty.

Engine & cooling
Manufacturer diagnostic bulletin2018, 2019, 2020, 2021, 2022, 2023, 2024Coolant loss from the V6 coolant pump
Repeated coolant loss on a V6 SQ5 needs an active-leak check before any pump replacement.
Audi published a diagnostic procedure for coolant loss on 2018 to 2024 SQ5 models with the V6 TFSI engine. It tells technicians to locate the leak precisely and warns that a small trace in the pump drip cup can be normal. A reproducible leak, rather than residue alone, is needed before replacing a component.
Symptoms to compare
- Coolant level falls repeatedly
- Coolant warning lamp appears
- A confirmed wet leak is found at the coolant pump area
- Dried coolant residue may be visible in the engine bay
Other ways owners describe it: SQ5 coolant keeps dropping; pink coolant under Audi; coolant warning comes back; Audi water pump leaking; sweet smell from engine bay; coolant crust near pump.
Which vehicles the source covers
- 2018 to 2024 Audi SQ5
- V6 TFSI engine
- All bulletin criteria and the exact leak location must match
Audi's bulletin is based on vehicle configuration and confirmation of an active leak, not a stated mileage threshold.
Manufacturer position and diagnosis
Audi tells technicians to clean and dry the area before checking the level at idle and higher engine speed. A pressure test and pump vacuum-line check then identify whether a component is faulty.
Confirm the exact leak sourceAudi or cooling-system specialist · Diagnosis before repair
Have the cooling system inspected under Audi's published procedure. It combines a pressure test with a pump vacuum-line check and allows replacement only after the leak source is confirmed.
Limit: Residue in the pump drip cup by itself is not proof that the pump must be replaced.
Log the cold coolant levelBasic observation · 5 minutes
When the engine is completely cold and the vehicle is level, photograph the reservoir level and note any warning date. Repeat without opening a hot system.
Limit: Never open a pressurized or hot cooling system.

Manufacturer bulletin · May 17, 2023
The bulletin covers 2018 to 2024 SQ5 models and separates normal trace residue from a confirmed leak.
Confirm who pays before authorizing work
A recall remedy follows the campaign and VIN eligibility. A service bulletin provides diagnosis or repair instructions; it does not by itself promise payment. Manufacturer warranty extensions and support programs have their own conditions.
