RP number = replacement parts number. Basically its a number that identifies the day the car was built, it can be found on the label by the door that has the tyre pressures on it.h2ocooler wrote:Ok ok im a noob i guess, What is RP number? and can anyone tell me what Eolys fluid my Mk1 03 2.2 SX C5 will take, this has now got me worried and i want to top it up.

Before RP 9491 the C5 used DPX42 fluid after that they use Eolys 176 fluid. I'd say an 03 plate would almost certaially use the later type with the 75k intervals.
When they changed to the mk2 C5 & other later models it gets even more confusing.
