“I noticed my car started to lose coolant, I checked my water pump and I saw there was a leak on of the hoses. Once I discovered that I also heard a tapping noise coming from the engine. I took it to my local Audi shop, and they discovered that my pistons were going bad. They told me I qualified for the extended piston skirt warranty for my car. While my car was in the shop they replaced all 6 of my pistons. When they told me my car was ready for pick up I picked up my call, drove it for 20 miles and my car started to make a louder tapping noise from the engine bay. …”
