SL/R231: Hydraulic fluid
Could someone point out what hydraulic fluid to get. I had a leak in one of the hydraulic pipes in the trunk so now need to refill the hydraulic fluid. What fluid should i get? And any tricks to refill it. Did some research and couldn't find what to get. Stealership is charging arm and leg for it.
Thank you for help




I think the easiest way to fill the reservoir is to use a syringe with a tube attached to it. That’s what the official MB tool looks like.
There should be a fill plug on the side of the plastic reservoir. (see last picture)
It’s fairly self explanatory, but I’ll try to post the procedure from the WIS (for the R231) when I get back into my shop, and have access to my laptop with SDS.
The link above is for Hydraulikol from FEBI
Heres the Mercedes official version
