I have just about fixed my HVAC system. Found the leak and am now about to reploace the burnt out electric pump. Before I do I need to know what the vaccuum control valve looks like. When the engine turns off the vaccuum in the reservoir leaks straight back out into the engine.

The vaccuum lines looked like a dogs breakfast. At the moment I have vaccuum going direct from manafold to reservoir - obviously not right. I have pulled the burnt out pump out.

Under (I think) the fuel inkection maifold there is a vaccuum hose, what should it run to?? I would really appreciate some help with checking the motor vaccum lines. It is a 1983 735i


Thanks Martin
