My '87 Golf Cabrio has (according to ETKA) an ISV with PN 037 906 457 D...
and ETKA also says you can use PN 027 133 459 A.

These same part numbers appear for the 1990 and 1991 Cabrios.

The ISV that I replaced in my 1987 Vanagon GL has PN 025 906 457 A (and ETKA
lists this as the correct ISV for 1991 and 1992 Vanagons too).

Now the 1987 USA Golf and Jetta both  have a completely different ISV with
PN 034 133 455.
