2018 Audi Q7 - Piston ring problems common?

The Audi 2018 Q7 model has been affected by piston ring problems. The piston ring serves as a seal between the piston and the cylinder wall, to prevent oil and combustion gasses from escaping, and for heat transfer. This issue, if confirmed on a specific vehicle, can lead to excessive oil consumption and potentially engine damage. In some cases, the piston rings may become worn or damaged, allowing oil to leak into the combustion chamber and burn. This can cause the vehicle to produce blue smoke from the exhaust, and can also lead to decreased performance, increased fuel consumption, and engine damage.

Audi has acknowledged this problem and has announced a recall of affected Q7 vehicles. The recall involves replacing the piston rings in the affected vehicles. If you own a 2018 Audi Q7, it is recommended that you contact your local Audi dealership to check if your vehicle is affected by the recall and to have the piston rings replaced.
