Tried the Passat at the weekend with CC, without CC and windows open.

Used Cruise Control to keep same speed 60mph for 15 miles on each test

On board computer showed no differnce in mpg for each test. Crude I know but had to try

every year during the first hot week we are mobbed by customers complaining " my AC's not working, it worked fine when i used it last summer" etc

so in their quest to save money how does £100 to recharge the system sound or another way is in their quest to save a rainforest by not turning it on because of emissions has led to a leak of R134a refrigerant which is a known greenhouse gas with very severe penaltys for accidental discharge!
The 1997 Kyoto Protocol puts R-134a as one of the 6 greenhouse gases that must be handled with extreme care.


anyway the morale of the story is if you got it you may as well use it :thumbsup:
