Aircon high pressure sensor removal..
« on: July 23, 2015, 04:12:32 pm »
Has anyone had any experience changing the high pressure sensor on the aircon pipes near the aircon compressor? Is it easier removing the pipe work from the car to get to the sensor? My car is a 58 reg Pirelli Gti and I've heard the later cars have a removable sensor compared to the early models which couldn't be removed from the pipe work?

Hi there

I've done this on my Mk5 GTI DSG '05 plate.  No need to remove any parts but you will need a 'crows foot' socket attachment, a long extension bar and a ratchet.

The pressure switch - down to the left as you look into the engine bay, between the radiator and the alternator and mounted vertically off the aircon pipe - is a screw off/on fitting with an electrical connector on top that fits onto a Schrader-type valve (like a car tyre valve) on the pipe, that allows the switch to be removed with minimal loss of refrigerant.

You need the crows foot as it grips the hex body of the switch from the side (you can't stick a socket on it) and the extension bars allow you to work from above to loosen/remove the old one and then refit the new one.

Hope this helps!

Cheers for that mate...
The only bit I was unsure about is that the new pressure sensor is slightly different to the one that's on the car, but TPS assured me it's just because it's the updated version..

As said above
Relatively simple job and my mate even managed it with just a stubby spanner so seems it's possible without a crows foot attatchment although deffo fiddly with spanner
10 minute jobwith right tools  :happy2:

I might try with a stubbie first... My local tool shop only sells the crows feet ones as a set and are about £25..

The pressure swith was £52 from TPS.. Think they are £72 from VW!

Yep, but you have a 2-year warranty on the one you bought from TPS...  So not all bad!

Managed to change the switch easily with a crows foot spanner.. The new revised switch only needs a 24mm socket!

Air con re-gassed as a small amount had leaked due to the faulty old switch..
Luckily the compressor is fine too...
Icy cold aircon now!
