The oil alone was priced at $239.92. From the limited amount of research I’ve done it appears the C5 RS6 holds 8 quarts or 7.5 litres of engine oil. That works out to around $30 a litre for the Castrol SLX III. The Audi Maintenance check sheet states: Engine Oil: Replenish VW standard VW 504 00, VW 505 01 Filling quantity 7.4 litre.
I was also having some intermittent problems with the rear interior light. The lighting assembly was inspected and I was told that it should be replaced.
Quote from Audi was $268 for the part or $374 for the part and installation.
I checked on the ECS website for part number 4B09471116PS and found that they had the assembly for $196.51USD. The downside is they want $76USD to ship the part which makes it more expensive than buying it directly through Audi Australia.
I have my eye on some other parts on the ECS website so I will hold off until I decide to buy multiple items to offset the shipping costs.
