thanx phil, much cheaper than i expected!

dont supose it gives you any detail on those in your catalogs does it? maybe a picture? or a mini-spec sheet on control pressures n stuff?

if not is there a bosh techy helpline i can ring to find out that kinda stuff?

spose i can try ringing saab n see if they got a thing like microcat with pics on there... worth a try...

just thought of one more part... an XR4i THERMOTIME SWITCH (aka Thermal Time Switch)
