I've just noticed that my C5 that I bought 5 months ago has green stuff in the suspension reservoir. I only noticed as there is a slight leak and I got some LDS to top it up. LDS is orange.
I know that only LDS should be used in these so I am planning to drain and refill it. I'm still battling with a ESP/ASR fault so want to reduce as many variables as possible. Descriptions and manuals say to use a Facom 920 brake bleeder which seems to be some professional tool to pressurise the system to 0.5bar (7psi). Are there any cheaper tools or tricks to do this? I was thinking about using a cut bike tube and hose clamp to put a valve stem on the top of the reservoir and pressurise with a small tyre pump.
Any other suggestions?
