my car is an 86 tqw, but being euro spec has a KG motor.  this is
similar to the US-spec 85 5kt motor (KH).  i can't read a number from it, but
my CPR looks most like 034 133 403(A/D) on my fiche (which calls it a warm
up regulator).  according to a parts catalog i have, your number was
used on 81-83 5k & 5kt in the US.

the atmo port is as you described.  however, mine only has the 3mm
nozzle, no 6mm nozzle.  the 3mm vacuum connection runs to some type of
vacuum switch mounted on the firewall next to the coil.  this switch is
fed with manifold pressure.  btw, i haven't figured out what this switch
is for.  it is mounted in the same spot as the wastegate valve on the 86
and up 5kt's.  i have not found it in the bentley or the fiche.  the PN
is 437 906 283.  anyone have any ideas?  phil?
