HI there!!!
I am currently working on the EVAP System and and there are a few Hose Routing Diagrams in the net but not really a particular one for my 1994 850 T5.
So maybe somebody can help out. I have the "Vacuum Hose Routing #9454041"

1) On that diagram they are refering to "Canister" , i reckon thats the charcoal canister?
2) That Valve under the Battery, is that the Shut-off valve? If not, what is it??
3) The 2 Check-valves coming form the purge valve, one hose (with that check-valve on it) is going to the intake manifold and the other is going into the plastic pipe which goes into the turbo???? Is that correct?
4) What is an ARW?? (mentioned on the Diagram)
5) I have got an open end from a small hose in the corner of the left indicator...really hidden in that corner...very small hose...maybe 2 mm inner diameter....i think it goes back into cabin with 2 other thin hoses.......is that for a gauge ?? Where is that open end connected to??
Sorry that i cannot post any photos but i do not know how......
Any help would be really appreciated!!!!!
Cheers!!
