Hi Mark, I had mine refilled two months ago, the car was a year old this june just gone, but saying that I use my air con all the year round, for demisting etc. I use to be a grease monkey, till I had a accident in work which has left me in a wheelchair, and I hate funny noises, but now I can't do nothing about it and I have got to leave it to the dealers, its dame frustrating, when you know that the dealers get the car in and it sits around for a hour in the workshop do naff all, then they come back and say sorry sir, we can't find any problem. Sorry glad I got that off my chest. :) Regards, Mark :)
