The contact owns a 2014 Audi A6. The contact stated that he became aware that the vehicle was experiencing abnormal oil consumption. An unknown dealer was notified of the failure, but an oil consumption test was not performed on the vehicle. Additionally, the contact stated while driving 65-68 MPH, the EPC and the check engine warning lights were illuminated, and the vehicle started shuddering. The contact was able to veer to the side of the road. The vehicle was towed to the residence. The vehicle was then towed to an independent mechanic, where it was diagnosed that there was no compression in cylinder #6. The vehicle was then towed to another independent mechanic, who determined that the engine needed to be rebuilt. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the VIN was not under recall. The failure mileage was approximately 149,087.
My car was manufactured with defective pistons. The pistons are resulting in reduced oil pressure in my engine, which can result in a sudden loss of power. I had my engine inspected, and the attached photographs depict that the original pistons that shipped with my car caused scoring to the cylinder walls which is causing metal pieces to collect in my engine. In addition, Volkswagen Group of America, Inc. acknowledged that the pistons need to be repaired in my car, and quoted the repair using an updated design, so they are aware of the issue and have knowledge of it. While the defect existed during the warranty period, VWGoA refuses to repair or replace my defective engine under warranty.
