The clutch dose not engage when I go from econ to normal.

I know the A/C has a pres switch on it to protect the pump if the pres is to low, but if I cant find the LOW pres valve I cant see how I can check the pres.?

I did have VAGCOM till I dropped my laptop a week ago. I will have to try and steal a mate laptop to check the clutch.

Cheers for your help Conan (the Librarian).
