Quick update Took the car to the indy today who had a glance over it - couldnt really hear how noisy the fans were as the alarm was going off in the unit next door but plugged it into VDCS and it was saying the aircon pressue was low and also a probable issue with a pressure switch. They advised me to go get it re-gassed and to take it from there.
Took it to be re-gassed and confirmed it had a leak coming from potentially the pipe that goes into the compressor but would need to take the front of the car off to have a look. Said would probably be about £300 to replace leaking pipe..... But then no guarentee that would resolve the issue as can't test the compressor untill the leak has been fixed. Also said this would account for the noisy rad fans?
Starting to look like a right money pit - Any advise/Help would be greatly appreciated!
Cheers
