    I'm looking for switch #61311364116, which is part of the load leveling suspension on my 89 E24. I've checked dealers, both factory and private, around the nation and all said it was "on back order". Any ideas? Many thanks

    Did you talk to ECS? Their website says late April expected shipping date, maybe a sales rep. could confirm. Realoem.com price says $94, ECS & others are almost $300 - oof! Fwiw, given the maintenance & parts expense, many switch to conventional shocks/suspension.

    Many thanks! Called today and ordered the part which should arrive in three weeks.

    Actually the part never arrived. It's on still on "back order". The good news is that the switch is not leaking much, more like a weep than a leak, and the system is still working well. So I'm prepared to wait along time and, at this point, not spend thousands removing and replacing the suspension.

    Is it possible the pump is leaking & not the switch? I don't know the construction of pressure switches, but since the diagram shows it mounts to the pump, speculating that's a possibility. From the post linked below, these systems apparently operate at extremely high pressures - wow!

    Maybe someone on these forums has some insight - as mentioned further down in the thread, hit up the E32 section on bimmerforums - there's also old-school bimmer expertise on myE28.com, which obviously is 5er-specific, although there is lots of cross-over on older BMW's.
