Hi
Just had my A610 air conditioning repaired which entailed renewing pipe work from the compressor to the mid car joints this was all done with the car on the ground with car jacked up one side then wood blocks under wheels which gave him enough room to slide underneath to renew rubber pipes and re attach to the metal pipes .Pressure tested then vacuumed and finally re gassed to the correct weight .now have ice cold A/C and cannot recommend highly enough .The price was a pleasant surprise as well.
He is based in Folkstone and will travel.Seemingly has done two other Alpines and knew exactly what to do.
