[topcyclist]

Hi I have a last edition S8 on a 2002 plate , can anyone tell me what the model number of the gearbox is ? Also I am talking to Technical Automatic Services about an oil flush , has anyone any experience ? They seem to know about Audi's ... Any indication of what an oil change shoul dcost ? Going to be interesting seeing hte state of it , 204k miles on the original box !

Thanks , Steve
