Wade sensing!!
Folks I don’t have wade sensing which is in some ways disappointing especially as I thought it was standard?! I’ve read somewhere that when wade sensing is engaged. As well as a graphic representation of the water depth on the display, the air vents into the car close off to help prevent water entering the vehicle.
My question is if this is the case and I don’t have wade sensing, is there a possibility of water entering the vehicle via the air vents? And if so surely this is a design fault because the wading depth is a generic depth across the disco5 range (with air suspension)
Thanks

Wade sensing is the least useful gimmick on a D5. It looks flashy, but doesn't actually do anything useful.
It doesn't close off any vents, all D5's have the same wading depth regardless. If you go too deep, you'll float away and if water is going to get in, it will.
All wade sensing does is tell you how far up the side of the vehicle the water has got. You can tell that by looking out of the window.
What would be useful, but there is no way it can tell you, is how deep the water will get as you drive further in to it, whether there are any large boulders, tree trunks or potholes ahead under the water, or how fast it is flowing. Even quite shallow water can sweep a vehicle downstream if it is flowing.
My D5 has it, but I don't use it for any decision making about safely driving water crossings.

Thanks I had heard it was not as useful as it perhaps appears. I just like my gimmicks and toys I guess 😂

I’ve been through a few fords and unexpected floods in my time,, even stopped halfway across Holy Island causeway as tide was coming in to photograph Eider ducks out of the roof…much to the bewilderment of people sensibly stopped on the shoreline.
I actually started to feel the car move sideways as the tide lapped the doorsills…and that was the heavy D4…..soon high tailed it to the shore. Not a pleasant or sensible experience in hindsight.
I stay away from wading these days.
I am reminded of a retired RAF flight engineer who came to work for my company some years ago. When asked by one of the girls in the office to sponsor her for a tandem parachute jump he remarked….”anyone who jumps from a perfectly serviceable aircraft needs their head examining”.
I tend to feel that about needlessly taking cars through deep water. Probably getting too old.
