I have a feeling there is probably a problem with the aircon now haha.. i'll have to see.. don't really use the aircon much but i have found out from a friend which said apparently when you press the econ button this turns the aircon off completely? as i know the aircon is running at all times in the background.
Will have a look at the small fan with the aircon switched on later.
Just to be clear though i think its the bigger fan of the two is whats making all the noise and the fact that it seems to be on fairly often and loud which i haven't noticed with any of the older two MK5's i've had in the past thats all.. So it may be that nothing is wrong with the aircon.. I may just be overthinking about it but thought id ask as its better safe than sorry they say
Thanks fella's for the pointers
