Hey guys,

I have a taxi-spec 250D 1987, and it's got what seems to be an orthopedic seat. (driver's side only)

There's not a lot of material on this, apparently they were more common in the SELs.

Mine doesn't seem to work - if it does, then the amount of air going into the back support is minimal. I really doubt anything is happening as I adjust it, unless the nervous system in my back is completely broken.

Just wondering if anyone has any pointers on what is probably wrong? The central locking works, and if I've understood things right the central locking pump is the same one that supplies to the seats.

Could the controller widget thingy be broken, or are the hoses more likely? Anyone know how these seats work?
