850…2,4 ltr….170 HP…10-1996…has someone exactly ready like the control of the secondary pump pump funzt? I have now put all parts new or used there and already together. When starting the pump does not jump on but the solenoid valve opens approx.10 sec after start the secondary vacuum hose from the DK to the check valve at the A-cracker. I opened the new relay for the pump and the connected onboard voltage via screwdriver forwarded to the power supply d it pump. Then it starts properly. The blue/pink control cable has all the time also on board voltage, when ignition, as well as when the engine is running. Sure this cable comes from the black box but for that I have no timetable. The control cable for the solenoid valve has the same colors and should also follow the same service as the control cable of the S-pump……but continuous current on DEM !!! cable makes no sense and the relay does not work (Aftermarket) Sweden.de. So, who has something to write about it. I want to finish this… So I need to put together the power thing, who decides how long this system starts, there is another relay in between, come the control cables directly from the MSG…
