'87 5ktq ISV saga

[Eric_R_Kissell at email.whirlpool.com]

I looked at the ISV's in my two Type 44's.

1986 5000cstq - ISV is VDO
Audi P/N 035 133 455F
VDO Number: 408 202/008/008
The Family Album also shows Audi 035 133 455F
The plug is Audi P/N 171 906 230

1989 200q Avant (MC-1) - ISV is VDO
Audi P/N 035 133 455F
VDO Number: 408 202/008/001
The Family Album also shows Audi 035 133 455F
The plug is Audi P/N 171 906 230

Both of these were replaced in the last 4 months and the ISV's I replaced
were the same VDO part. There were no questions when I ordered it and the
plug was right.

You probably already know this, but TPC shows the following on their web
site:

035 133 455F
   IDLE STABILIZER VALVE
      84 Only   5000
      84-88     5000 Turbo
      86-88     5000 Turbo Quattro

034 133 455
   IDLE STABILIZER VALVE
      85-87     5000 - Thru Vin: 44-H-040273

034 133 455B
   IDLE STABILIZER VALVE
      87-88     5000 - From Vin: 44-H-040274
      87-88     5000 Quattro

035 133 455F
   IDLE STABILIZER VALVE
      89-91     200 Turbo
      89-91     200 Turbo Quattro - 10 Valve

034 133 455B
   IDLE STABILIZER VALVE
      89-91     100
      89-91     100 Quattro
      91 Only   200 Turbo Quattro - 20 Valve
      92-94     S4
      95-96     S6

077 133 455A
   IDLE STABILIZER VALVE
      92-93     100
      92-94     100 Quattro

078 133 455B
   IDLE STABILIZER VALVE
      94 Only   100

I have no idea what this is about a small plug vs. a big plug or Bosch vs.
VDO. Everything indicates that your 1987 should use the VDO like my two
cars. You did say that you have a 1987 5kcstq, didn't you. If it was a
non-turbo it might be something different, but I have no idea what that
would use except that it is a different P/N. It looks like all MC engines
(i.e. 10v turbos) in 5000/200 models from 1986 through 1991 used the same
035 133 455F ISV which is a VDO in my cars.
