Cold start problem

I have an 1986 Audi 5000s with a 2.2 l five cylinder engine with 109,000 miles that has a cold start problem, runs great when it starts. Replaced the thermo time switch, the cold start valve, multi-function temperature sensor and the coolant temperature sensor. Haines manual says there is a frequency valve relay that controls the cold start but cannot locate it. Help, I want to get this car running for my college student daughters.

I show a wastegate frequency valve? It's next to the ignition coil. And a wastegate solinoid, next to the distributor.

I check and there is not a relay next to my coil. Need further help thank you :) Tore the dash apart and traced the wiring from the cold start valve and the thermo time switch to the ECM and was able to find a used one. Seems to have fixed the problem
