Both of these items have been discussed recently on this forum, but not
specifically for the diesel engine (CS) and there was no definative outcome
if I recall.  I have placed an order for these items to fit my 82 Diesel
Westy but there is a great deal of confusion about both of these parts and
their numbers.  I have searched the archives but did not locate a definative
answer regarding the diesel versions of these parts.  The vendor I discussed
these with did a lot of cross-checking with Bosch part numbers, etc. and
could not resolve either of these.

Does anyone actually know which spec oil pressure switch is correct for the
82 diesel?  ETKA has 028919081D as .25 bar, blue and 021919081B as .15-.45
bar, white.  The clearest vendor description is Bus Depot, who's only
listing is 028919081D for .15-.45, white.  Exactly opposite of the ETKA
listing.  Seems totally confused on other websites and many don't list the
pressure spec only the colors which can be white, grey, blue or brown.

The thermal sensors for the water temperature guage and (I believe) the glow
plug temperature sensor are called out as the same part number on ETKA as
049919501, although the electrical connectors for these are different, with
the guage connector being a "disk" and the glow plug sensor being a spade
lug.  Does anyone actually know if these two parts are the same now?  The
ETKA illustration 136-05 shows these as different connectors (and even
different threaded end size!) but its only a drawing.

Thanks in advance for any help with this.  I know that lurking out there is
someone with these answers.
