Hello Mate,

 They would be the fuse for the starter motor and that with a 8mm bolt holding them into position? Ive checked these with a multi meter all seem OK ill get some electrical cleaner today and a small wire brush and see if I can clean up better.

Check all the high amp fuses in that fuse box 50A is the feed for the fans.

Hello,

 All fuses checked and all cleaned up, ASV seems to be working, no engine light or fault codes on VCDS. Still no air con or condensor fans. Would this be coninsidance that the AC needs regased.

Use VCDS to run the fans in output test for that module.

Hello,

 Output test was done via VCDS and the fans worked perfectly and all seems good, thought we would try degassing and still not working at all, recovered about 320g of r134a and could only get 440g back in for some reason but the system should hold around 520g ish.

Compressor pulley seems to be turning ok, could it be the pressure switch on the compressor suction/discharge side?

Any more help would be great.

Cheers Dan

The same output testes could be used to show the compressor draw current which would confirm it's operation.

Common failure item on that side of things:-

The switch is a very common failure item but would normally (but not always) show as fault when scanned.

If you fit a new switch fit a new seal its best practice!

However, the best advice I received was to re-gas and make sure the leak detecting dye is added which will allow fault finding of the system components!

The compressor pulley turning is not an indication of it 'working' as it does not have the standard type clutch mechanism. It turns all the time even when off on these cars.

Look down at the pulley, if there is a centre bolt protruding then the engagement plate is probably gubbed. Search for 'delphi fix' and it should have a post by me showing what I mean, the splines wear off on the engagement shaft.
