The instructions for the SY series cars are appropriate for the SZ cars as well as long as you remember:
1. You're going to use LHM+ (Liquide Hydraulique Minerale+)/HSMO+ (Hydraulic System Mineral Oil+) and not RR363.
2. You do not have height control rams, but instead have the corresponding bleed screws for the rear struts/gas springs.
You are still bleeding the system from its end points, the calipers and the rear struts/gas springs.
I have never bothered to bleed the accumulators since if you pressurize and depressurize the system several times, which typically occurs during the whole "flush and bleed process," all the air has already been expelled from the accumulators before you start working on the end points in the system: the brake calipers and rear strut/gas spring bleed points.
In all other respects it's the same as far as the bleeding process goes. You don't, of course, have the whole reservoir sludge check to deal with.
HSMO+/LHM+ is available via amazon.com. I'd still check with the local Bentley dealership as it's entirely possible that it will not be any more expensive through them. You can't know without checking. HSMO+/LHM+ is made by TRW, Pentosin, and others in addition to Castrol. Just make sure you're looking at automotive LHM+ if you go that route, since there are LHM+ types meant for bicycles. You could also check with citraulics.com or daveburnhamcitroen.com to see whether they sell LHM+ or where they source theirs from.
