 After purchasing 4 Audi's from the same dealership I am at a loss for words.We bought an extended warranty to 100,000 miles.We had ongoing issues with oil and at 82,000 miles the pistons were replaced.At 103,000 they now tell us, after all services were performed at the dealership,there is a problem with the engine compression.They say it is our problem.Wow, I spent over $42,000 on a car that now will require a new engine and is over the warranty by 3,000 miles.I thought Audi was a premium brand that stood behind its product and appreciated a loyal customer.I guess 4 car purchases does not count for much these days.I don't think I'll be buying nor recommending Audi ever again
