Audi a5 2009 is not a reliable car i will never buy another audi product in my lifetime. i cant believe how i thought i was alone with the misfire issue and i find in my research there are many others with the same issues for various models unbelievable. had i search this product, would have been my only wish. the car wouldn't even start up today. had this car for only 8 months. at 45,000...
