well guys the tag says it all really symptoms were aircon was requiring a top up every 3 months obviously as the aircon gets empty the compressor gets noisy and vent temperatures were iffy in that on setting 1/2 you could get reasonably cold air but 3/4 the air got warmer add to that a spot of pag oil on the front of the condensor and a hissing noise. still had cool air during the heatwave as my local ford were busy so gave me a free drain and refill to tide me over till it goes in on the 18th of june.the warranty company will love me lol but thats what its for
