In the interest of sharing - I've wanted to replace my original shocks with same spec OEM Sachs but as already called out on this thread they are no longer available, albeit may still be available from BMW which I can imagine would be painful.
Anyway, after scouting around I managed to find what looks like OEM Sachs for like for like replacements, the pain is this seller is based over in the USA. He's now got 1 pair left and happy to ship to the UK......at a cost. As said, thought I'd share -
