Took out a D40 Double-cab outlaw for a test drive this afternoon.
Everything was fine with the exception of the air con - it kept making these horrid wheezing noises intermittently.

Is this normal? Or was i driving a duffer?

Would appreciate some input as i've just plumped for an Aventura, in black, for March delivery - want to make sure this is a noise i will not become familiar with

I guess its normal, mine does it when AIRCON is on.

Mine does it as well! Asked my service guy about it, he said its normal? Pain in the butt!

yep they all hiss like that because it constantly cuttting in/out to keep the cab dry, you can turn it off, b cab will get damp.

Trn up the radio or drive faster

I have the same problem and insisted that they fix it at the shop. Had 5 guys trying to solve the problem but in the end was told that it is "normal' for the D40's aircon.
Wonder if the buzzing make Nav drivers more aggressive...

A/C Noise

I picked up my Outlaw on the 1st March and have tested my a/c quite a few times after reading this thread, also I am a refrigeration engineer and over the years I come across alot systems that hiss badly on initial start up but then quiten down after a while. Unfortunatly this hiss cannot allways be stopped, but on some systems it can be greatly reduced by recovering the gas and evacuating the system for a few hours at max vac and recharging with new R134a gas to the exact amount and not a gram more. the point being that it is possible that a the factory the system was not evacuated correctly and maybe leaving some air in the system, our maybe overcharging / undercharging the system.
The fact is that not every system is noisey. and mine is luckily hardly noticable.
Food for thought

Cheers for the postings

I'm picking my D40 up next week (only 6 days to go )
I'll keep an ear out for what it sounds like.

Yeah, mine hisses too, has done since new, dealer says normal

It seems to be a fan issue more than A/C. If I switch off the A/C then the noise is still there. Gets louder if increasing the fan speed. :x
