Which hydraulic fluid?

Gmac · 30-07-15, 06:16 PM

I noticed the other day a bit of a leak of hydraulic fluid, and on checking the reservoir the level is below the minimum.

So what hydraulic fluid do i need and where should i get it from? It's for a 20v ur quattro

Likely the same as in other audis of the era - green G002000 mineral oil, as also indicated by the green PAS reservoir cap. Only, AFAIK, Audi recently discontinued it, because it was superseded with some synthetic oil, which was again superseded by some synthetic oil. You can check that out at your local VAG dealership. AFAIK there are some alternatives available on the internet, and, I guess, it's also supposed to work with some of the newer oils, if the system is flushed - I've got red synthetic oil in my A90q, filled by previous owner, the only complaint was that once, when I had in -15c cold start the engine and immediately drive it out of the garage, turn it around and drive it back [because the cooling system was empty], afterwards I found small amount of PAS fluid on coolant pump housing, leaked by PAS pump, but that could be because of the age of it.

I've always used mineral LHM fluid in mine, no problems in 25 years of use in various audis, switched to synthetic LHM for the 02 plate Golf TDI and 06 plate Polo. Its the same stuff as used in Citroens or is it Citreons, well you know those French cars with funny suspension.
