SMG Hydraulic Fluid (Pentosin CHF 11s)

[mikeyb74]

Does anyone know the capacity of the hydraulic fluid that goes in the white expansion tank on the passenger side of the transmission in a SMG equipped car? The Bentley does not state the capacity. Number 1 in the diagram.

1.5 Liters for the M54 (1.7 for the S54). Page 230-2 in the Bentley (it's under Transmission Fluid Service, not the SMG section).

That is for the tranny fluid which is also listed under the (Transmission Fluid Service for SMG) Page 231-2. On page 231-3 it states to fill to the "MAX" on the expansion tank.

Roger that. My bad. Standby-- looking...

It's probably under a liter.

[kayger12]

Well, I've gotten a good education on SMGs, but no quantity, lol. Sorry-- I rarely come up dry on a search, but this one's got me.

If I bought a liter bottle, rest assured it would take around 1.2 liters. I would think a liter would do it, though.

Thanks for your help. I will purchase two liters of Pentosin CHF 11s. That stuff is pricey. $20.95 a liter.

[kayger12]

Agreed. I would buy the two to be safe. Should be able to return one if you don't need it.
