I need to replace this pressure switch on the aircon rad of my 2008 s Line.
I bought a genuine one from the dealer together with a new o ring.
When I unscrewed the old pressure switch the old o ring came off with it.
I have changed one of these before on my B6 but am a bit puzzled as to how to fit the o ring
before screwing the new switch onto the threaded part containing the Schrader valve.
It looks to me as if I should slide the o ring over the threads so that it sits at the base of the threads
and when the switch body reaches it, the o ring is compressed by the smooth tube below the female threaded
part of the switch.
Is that the correct approach?
