When in acces mode is the car on its bump stops?
And in the valve block what its the smallest air line in the left corner for ?

No it is not on it's bump stops it is 40 mm above them. Small 4 mm pipe is for venting air from below diaphragm valve when compressor stops. It is vented into the loom.

Thank you always wonderd what that pipe was

When compressor is running, diaphragm solenoid valve opens and applies air pressure to the under side of diaphragm to hold it closed so tank can be filled. When compressor stops diaphragm solenoid valve closes and air holding diaphragm shut is vented. So the diaphragm can then act as the exhaust port.

I always thought it came out of the exhuast silencer but obviously not .

The air that comes out of the exhaust port when compressor stops is the high pressure air that the compressor has been filling the tank with. That is released when the diaphragm valve opens because the air holding it shut has just gone down the little pipe into the loom.
