My non-functioning rear multiram is getting harder to diagnose! I am almost fresh out of ideas now.
So far, have checked the following:
1) There is definately a good vaccum
2) Vacc tank one way valve IS working
3) Tech2 is able to actuate both rams with the engine off, so it's also obviously storing a good vaccum! And the fact that Tech2 can actuate it, means the wiring from the ECU is ok, and the actuator is OK
Yet I still cannot get the multiram to work, by blipping the engine. I've tried revving it hard, soft, midrange etc, it just will not function (I tried a different V6, which worked straight away).
I would really appreciate ideas, it's obviously not having an enormous effect on the car, it's still drivable, but I WOULD like to get the kick of the rear multiram!!
