You are being robbed at £487, here is my 2nd service invoice breakdown (this was a 'free' service so Audi Finance were paying), from my 20,000 mile report:
As a few of you have probably got your second services coming up here are the invoiced costs from my service package:
Parts: £130.25 (sump plug £1.58, Filter £10.43, Filter £13.36, Spark Plugs £66.60, Oil £38.28)
Labour £161.50
Total £350.10
I swear they see an RS badge and make up the service and parts prices then add a random number for fun!
Oh and not that you would but under no circumstances take your car anywhere near Cardiff Audi, they only like fleet DIEsels.
