Your car has CIS-E and does not use a warm up regulator (aka control
pressure regulator).  The function of that device (which is found in
CIS cars) is served by the differential pressure regulator under ECU

The besy source of info is the Bentley service manual for your car.
Also, your engine is essentially the same as the VW Golf GTI and Jetta GLI
engine from the same vintage, just mounted in different orientation.
