I'll have to check that Bentley illustration again. Unfortunately I don't think I have the normal amount of leakage. Earlier in the thread I had mentioned that I had to have the system re-charged 7 weeks after its initial charge, due to warm air blowing from the vents. I'd say that is a nice leak. Looks like the evaporator is the likely suspect which would explain why the dealership needs the car for a few days to rip it apart. We'll see..
