[s-cars] Lower back deflation

[Gísli Óttarsson]

The Recaros in my D2-S8 have inflatable lower back support.  Unfortunately,
the driver side leaks and I wonder what may be causing it.  It will inflate
fine, but will deflate in a few seconds.  Without this inflation, the seats
really suck!

Someone suggested that the cause may be a defective one-way valve.  Is there
a simple way to get to it and to check this theory?

Any other suggestions?
