5KCSTQ Cold Start Thermo-Time Switch?

[Louis A. Mulieri]

Hi,
	My 88 5KCSTQ is showing cold start system problems (cranks 5-10
sec before a few cyls fire, followed by slow and erratic speeding up to
normal idle and normal running). Probst shows the cold start vlave to be
controlled by a thermo-time switch having a 2-terminal connector.
Audi Archives claim this switch is located in block above cyl 2. All I
find is a single wire, slip-terminal sensor in the block at this location.
Bentley doesn't seem to indicate where the switch is located. And the section
on "Cold start valve power, checking" (page 25.100 for my CIS-E III system)
doesn't seem to include possibility of cold start thermo-switch
malfunction). Does my car not have a cold start thermo-switch or where do
I find it?  Thanks for any help with this.

P.S. Anyone know what size bulb to substitute for the cold start valve
coil when testing for the few second energization time?
