Dust!!

I’ve posted before that the D5 doesn’t seem as dust proof as the D4. This might be one reason why. These are our third row seats.

Tony have you got both grommets in place for the spare wheel winch?
The reason I ask is that when I was fitting my spare wheel winch adapter I used a mirror to have a look between the 2 floor skins. There appeared to be a surprising amount of daylight filtering into this space and I wondered if the lower skin allowed water to be drained out easily to give Land Rover the 900mm wading depth. That was the reason that I looked for a means of sealing the area around the winch so water does not come in and found the silicone tube that I bought from Autobarn, and cut roughly to shape.
The potential for dust ingress did not occur to me. I will be sure to put extra silicone sealer on top and bottom of the tube!

Hi Julia. Yes both grommets are in place. I have previously noticed quite a bit of dust on the lower one so it is obviously getting in somewhere. I haven’t had a good look yet to chase it down.

I have had a LR dealer’s head mechanic look at my dust problem. He said that it is probably coming in the vents that are in the frame where the tailgate closes; these vents have a rubber diaphragm in them and serve to equalise air pressure. He suggested covering them when in dusty situations. All sounds a bit dubious to me.
However, when I removed the rear load space cover to fit a Traxide system I did find a lot of dust around the grommet where cabling goes through to the trailer plug. So I gunked that up and I’ll see how it goes on our next trip.

Do you have the a/c set to fresh or recirculate? Fresh air and windows closed should keep the dust out.

Recirculate when dusty to pressurise the cabin.

Yep, recirculate.
Might also spray the door rubbers with lanolin. Dust will stick to the lanolin.
Lanolin does not damage rubber like some other sprays.

Fresh air and lots of it are needed to pressurise the cabin. Air will be drawn out from anywhere it can so force clean air in from the front.

Hi Graeme. The advice I have been given by various Land Rover mechanics for my D1, D4 and now the D5 is to have the recirc on on dirt.

The only time to use recirculate is when driving in another vehicle's dust, either from the car in front or from a passing car.

Pressurising requires air from outside the area being pressurised. Positive pressure from the outside is required so don't let the a/c determine the fan speed, instead set it quite high manually at least on half speed.
