WUR gurus
79SC. Cold control pressure = 0.5 bar. That's way too low. After 15 minutes with key in on position, it climbs to 2.0 bar. Still too low. System pressure = 5 bar. Residual pressure = 2.0 bar 30 minutes post shutdown. Vacuum on WUR port does nothing.
Is low control pressure a normal failure mode for the WUR? Thanks,

You'll have to make the WUR adjustable...to bring the cold and hot pressures up.

Check volatage to it. Pull the plug and start the car and check the voltage at the plug. I think I had similar press. when I lost voltage. The vacuume had no effect. How does it run. What happened when it changed? Have you seen the web site from the guy from rennlist. He is a guru I was able to e-mail him for some answers.
