2020 Audi Q7 Engine Problems

“I discovered this item while researching another issue. There was a class action law suit against VW/Audi for the Water Pump and coolant leaking into the system. The class action covered the year and model for my Audi (2020 Q7) but my VIN was not included. The class action ended in 2024. On 8/4/25, My water pump went out because of coolant going into system. A $6,000 repair. I brought the issue up with Audi. No response.”

“I’m having to replace my REPLACE WATER PUMP AND VACUUM LINES WITH RESERVOIR at 41k miles or it risk overheating the engine. It is a significant repair at a premature time. After researching, it has been reported there are historical issues with this and faulty parts.”

“While my vehicle was in for the Audi piston issue, they stated my water pump needed to be replaced and isn’t covered by a recall (yet). My vehicle had less than 42,000 mile on it.

I needed to pay over $1,700 out of pocket and was told I was saving so much money because they already had the engine apart because of the piston recall. This is unacceptable.”

Months later, I noticed increased oil consumption and loud engine noise. Despite multiple service visits and reporting these issues, Audi failed to properly diagnose the problem. In January 2025, despite a clear check engine light indicating a problem, Audi dismissed my concerns. Just weeks later, in February 2025, the engine catastrophically failed due to undiagnosed internal damage. …”

“the first indication of an issue was oil consumption. It was using more oil than usual around the 70K mile mark. Then it started misfiring, and soon after a knocking noise coming from the engine. There are no check engine light on, after bringing it in for diagnostics, it read that it was a spark plug, once they got into the engine they discovered the cylinder had been stripped from the piston. Yes the diagnostics came from our foreign car mechanic. no, it has not been inspected by the manufacturer or police. Just the symptoms. sometimes the light would come on, and then it would go off. …”
