Hi I've got a golf mk5 1.9 tdi 2004 recently the air con gave up the ghost so I took it too a local garage for a re gas and they didn't charge me for it because they said the compressor is in a nut shell f?cked so I purchased a second hand one from eBay got this one fitted which was also identical to the so called f?cked one any I've had the system re gassed and still no air con so today an electrician said to remove the power cable and test what voltage is going to the compressor he did this which is just over 10.25 volts he also tested the battery which was 12volts then 14 volts when I switched the engine on daft question do I need just the wire loom for £38 which VW quoted me please help Geoff

Could be anything. Surprised an auto electrician couldn't tell you for sure what's up. And not sure a Ford forum is the place to find an answer either!!

Is it hissing when you try to use it?

Does it hold pressure when you try to gas it?

How did they identify the compressor was broken?

What voltage should it operate on?

Geoffod

No hissing and it holds it's pressure mate all I've been told is the compressor should operate at 12v an air specialist has told me to do the 12v test direct from the battery while the engine is running so I can hear the compressor kick just to make sure it is working but I don't know how to do this as yet

You have had 2 posts and they are about info for a VW on a Ford site.

VW reliability. .

I know it's a ford site but you guys are supposed to know a great deal about cars or even be mechanics or engineers so will have worked on a great deal of cars other than fords I would imagine all I am doing is looking for some sound advice which most of the guys on hear have been great so far pal so cheers for the helpful reply not

VW don't make the air con compressor, but don't let that get in the way.

Get a fully charged battery and run a wire straight to it. It could be something simple like the low pressure switch thinking it has no gas.

Get vag com on it and find out exactly what's the issue. No point speculating.

Plus if you do buy second hand make sure you get the right one, think there are two makes.

If I was you I'd ring the local mobile air con man to come round.

I've had more help from you guys on a ford forum then a VW one I posted the same problem and you guys on here have been great am not just saying that either I've not heard a thing from vw either the tw&ts thank you guys any way Geoff I appreciate it

Golfs of this age do suffer from the hi pressure switch failing on the AC.

As above though it needs checking out properly, the compressor may well be f*cked..
