Air conditioning refrigerant leak

[llitvack]

Hi folks.
I just had the aircon guy out to the house to refill the refrigerant because the Bongo wasn't cooling in our tremendously hot weather! He discovered that the system wasn't holding refrigerant, and the gas was escaping. He will return to do a high-pressure test, to determine the source of the leak
He told me that the most likely escape route was through the heat exchanger/front aircon matrix.
Can anyone please tell me where, in your experience, the most likely source of a leak is? if it's the heat exchanger/front aircon matrix, then these seem to be fairly reasonable to replace.
Many thanks!

hi leon.

look under the off side, just behind the drivers door, you will see 2 steel pipes and 2 rubber pipes that go up through the floor into the heater aircon unit.

you will see 2 bolts that have a seal in them. in the link below. these usually leak, and are easy cheap fix.
