I think you're on to something here Stuart.  The regulator is still
made in Germany by Bosch. p/n 0 280 160 205. Good insurance against
the part going NLA. We know the part lasts at least 21 years. Pricey
at over $100 but if you install new and carry the old one as a spare,
that's some piece o'mind. I just replaced one that failed after the
engine fire and will probably post some pix of the interior of the
failed one.
