Air con

[Goran]

That is very cheap!
Its really good advice, I suspect mine only lasts 1 summer at a time because I very rarely use it. I'll try leaving it on auto after the refill and see how long it lasts.

After driving recently refilled A6 and S8 in some hot weather I can say that cooling performance on S8 is better even if aircon has never been serviced in 9 years I had car. A6 starts cooling almost instantly after re-fill but overall cooling performance has not changed, S8 takes a minute or 2 to start cooling but does better job after that. Not sure if I want to do anything with it at this point as I cannot use the same offer again. I think maybe if it ain't broken don't fix it.

On another note I have done some surveys among friends and it seems like I previously mentioned if you regularly use your aircon it seems to last forever but if you only use it occasionally you need to refill every 1-2 years and this even includes new cars. Obviously therre is slight fuel economy penalty if you use it all the time like me and I have not looked into how much money you loose on fuel compared to aircon re-fill. But I guess you don't need to run it all the time as long as you switch in on every now and again to get the gas circulating and draw some oil with it as well.
