Keeping out the dust

[pawky]

I'm just interested in people's opinions about what is the best way to keep dust out of the cabin when travelling dirt roads.

I have heard theories of Air Con on fresh full blast etc but I wanted to learn from other D3/D4 owner experiences.

Any ideas? Is there a magic method to prevent dust creeping in around rear door seals etc?

Thanks

Keeping your windows up helps!

X2. Following a mate, windows down, enjoying the view keeps very little dust out. As I found out recently.
Have heard air con on recycled air increases the pressure in the car keeping the dust out. Haven't tried it but sounds plausible.

I flick between recirculate on and off depending on dust. Recirculate only.....can't see how that increases pressure (unless its introducing air).

If you park you car and put aircon on with fresh air (step out and close doors)....you feel the air coming out the handles. If on recirculate no air comes out....so fresh air increases air pressure in the car. That's the way it works on my D4.

A/C on fresh not recerc and all windows up as Rich sugested this will preasurise the cab keeping dest to a min.

For me it's on Recirculation as its been the only way to keep dust out particularly up in the high country where it's as dusty as a.......well you know the rest. A good tip if you have been on a dusty track or following someone is to just check your air filter as well, mine was clogged after one trip!

No problem with dust in my D4 with windows up and the A/C on auto (basically fresh as far as I know). This was travelling on thousands of km of very dusty road including the Great Central Road, Plenty Highway, Kennedy Development Road, Cape York roads and tracks and other very dusty roads, travelling in convoy with 4 other cars. My pollen filter was probably full of dust but the car was good. I changed the air filter once on the trip as it (the filter) was very dusty and I tried to stay far enough behind the other cars so that there was no visible dust in the air whenever possible.

The main trouble I have is with my fuel filler flap not opening due to the mechanism filling with dust. I needed to spray it with CRC or silicon spray every now and then on dusty roads or the filler decided it wouldn't open. It happened again on the Australia Day weekend when we went across the Nullarbor and back including some very dusty roads from Balladonia to Esperance and near Fowlers Bay in South Australia.

I have always used a/c inrecirculate

Sorry for last post, bloody iPhone buttons.

As I was saying.

A/C on with recirculate as this seems to minimize the dust being sucked in and I have not had any problems with dust.

Windows up is also pretty handy.

Enjoy the new D4.

If driving in clean air then set a/c to fresh air and keep the fan high to drive as fast as you like. If following another vehicle and can't drop back to clean air then recirculate to try to minimise the amount that will inevitably get sucked in. Keep the windows closed in both circumstances.

Yep - a/c & recirculate for me too ... worked a treat last weekend up around Mt Disappointment area - very dusty tracks...

On my trip when passing road trains etc and having to stop in the massive cloud of dust or when following too close in a dust cloud I never had a problem with dust with the A/C on auto. I expect the pollen filter will be very dusty though. I just had my car serviced and the pollen filter was changed for the first time since the trip in September. I haven't noticed any difference since changing it, however.

Pretty much the same as most have said! I have the intake air on fresh direct from the outside via the filter and the fan on a postion about mid way on the dial or above so that I am creating a positive pressure inside the vehicle. This ensures no dust ingress through any gaps in the seals etc. I must say I have not detected any gaps. I also use recirculate if I get into close proximity to other vehicles or for passing traffic that may be generating a dust cloud.

Note: Once activated the recirculate automatically goes back to fresh after a set period. Not sure if that aspect is adjustable?

The net result is a clean and dust free (as much as is possible on my local dirt roads) interior.

Hold the recirc button in for 3 secs, and it will stay on indefinitely.
