[s-cars] Lower back deflation

[Gísli Óttarsson]

For the record, in case anyone is interested, this has finally been
repaired.  The fault lay with a small solenoid/switch which regulates the
pressure in the lumbar bladders (part number 4D0959931).  This thing goes
for 200EUR or 250USD (I priced it in both continents) which I thought was
rather steep., though not compared to the 500USD they were asking at the
local Audi dealer.

A dude at the local Recaro agent's came to my aid in diagnosing the problem
and installing the gizmo.  Good thing because after seeing a diagram of the
seat I would not have wanted to dismantle it.   The driver's seat in the
space shuttle doesn't have this many motors, pumps  and whatnots.

I am now happy as a pig in sh*t because I can't begin to describe how
uncomfortable this seat is with the lumbar bladders fully deflated.
