Fitting new pressure switch for air con tomorrow

[racingcar64]

hi all,

I have just bought a new air con pressure switch, opened the bonnet today and saw its slightly under the drivers headlight. Read up on how to take out headlight( without bumper removal) and I think I have got that. I know there are 2 torx no.30 and 1 hidden down the long hole, also no.30.

All I need to know is is the pressure switch a simple unthread and then thread the new one in?

Hopefully some lovely cold air tomorrow will follow!!!

Yup its on a ball valve so just unscrew 'carefully' and it should seal.
Mind the ball joint on the head lamp...stops you pulling it straight out and need a gentle pry...

Thanks....fingers crossed I can take the headlight out without removing the bumper.

Everything went perfect....except inhave got the wrong pressure switch, even though it was the one listed for my car... Can anybody tell me where to get one from?

I have found this one on gsf parts, i can pick one up tomorrow. looks like same connection for the wires, but slightly different shape!!! will this be ok.? GSF list 2 diffeent ones for my car. the one i have is the other one they have listed....

Yes I was given the square ish 4 prong one! Got
One from gsf parts picking it up tomorrow...it's looks slightly different in shape, but I suppose as long as the thread is all the same and the connector, it shouldn't matter....I spoke to Audi and they said the the first part number on your list, is superceded by the others, the one starting 3RO is the most recent, so i imagine they are all the same fitting? Thanks...
