Good afternoon ladies and gents, I have a a6 27t Quattro, its near for its service, I have recntly bought all the service bits minus the oil and sparks. Stealers were quoting me 120 for oil!!and 10 each for sparks!

Could anyone tell me what the idea is with oil? also what sparks are recommeded for these cars? 2002 model 100+ miles on clock.

Also can I upgrade my phone kit from the old nokia one that came in the car 6120 I think. Any links would be much appreciated.
