I drive a 2009 Audi A4 Turbo. and it has 56K miles and last friday it started to violently shake on starting. so i had to tow the car to the dealer. He checked the sparkplug and coil packages and they are fine. Dealer mentioned that it is because of Cylinder misfire and one of the cylinder has Zero compression, he said that i had to change the Cylinder head due to the burnt valves. and gave me a quote of 4800$ - is this a fair price for parts and Labour..? Can this be done any cheaper at local stores . I live in NJ and any guidance would be much appreciated. If there are bent/burnt valves is it needed to change the cylinder head completly..?

 

They don't call them "stealers" for nothin'.... I'd take it to a good shop that works on German Cars. Unless the head is physically damaged and cannot be rebuilt, $4800 is bit steep if you ask me.
