My SAAB and MB Hydraulics for convertible and as well as PS called for CHS115. I was so happy to hear my products replaced it and that saved me a boatload when a line blew out.
Hope that helps and explains why the dealer mechanics say to use it instead.
I'll keep that in mind. Was thinking of flushing it as it's still the original fluid, but will remove a little & look at it first.
I think
FCP Euro may have mis-listed the MB-branded PAS fluid for our car as although they say Q1460002 the picture shows Q1460001 and the URL link has Q1460001.
autohausAZ is all over the place.
They say this is the correct fluid:

While this is NOT the correct fluid!!!

Yet everyone agrees Pentosin CHF 11S is correct:

And that Mercedes Q1320001 is also correct:
