Can anyone shed any light on my DSC concerns? I noticed recently when towing a full load, (3.5 ton) that the DSC was kicking in on some of the bends, despite being at very low and perfectly manageable speeds and terrain. I was not in a situation where I thought the DSC was needed, and road traction was fine. I put it down to the fact that the tow load was high and thought no more about it.
This morning i was out with the family, 2 adults, 4 kids and some other stuff in the boot, and the DSC kept kicking in on right hand bends only. There was a bit of a load on, but not much more than normal really, and only on right bends, not the left ones. Thought it seemed strange. Any thoughts gratefully received!

If you haven't done so already, check your tyre pressures - especially on that side.
It may be a sensor that's gone though causing the DSC to misread what the D3 is actually doing.

| ....its another Disco system |
|
that's coming into use that is specifically to prevent the towed load affecting the stability of the Disco
I saw this demonstrated at the Coniston Hall experience centre....
they run car up to 30mph & then violently swing the wheel with foot hard down on accelerator pedal....the vehicle response is to slow down by not accelerating & alternate use of brakes at each corner to stabilise...
as far as I know this cannot be disabled & is there in the background looking for the signs of trailer taking over
don't know what acronym it has but it has one... BREXIT - done properly.

1) Check if the break on the front wheels fully releases. Had this on a Defender which had rost on the cylinders of the brake which was just enough to make the car belive there is friction on one side and started to break on the other side to slow the faster wheel down.
2) With loads on the hook (did you check the vertical load on the hook with a scale?) the front of the car gets lighter and the system may belive you are loosing traction....

Well it happened first with the trailer and full load on, but not noticed it since then till this morning. Brakes are definitely ok, changed them recently. I do have a very slow puncture on that side, but i'd only just blown it up this morning before the journey, and it only loses a couple of pounds a week. I stopped for a while at my destination, and then continued on my way, when I carried on with the same load, the problem didn't re occur. Bit of a strange one. It can be disabled of course with the button on the dash, but I don't really want to do that since it is there to perform an important task. I suspect there's nothing wrong, but circumstances were causing it to trigger, but I just wondered what conditions were causing it to fire despite having perfectly good traction at low speeds on a dry road. I can normally throw the old girl hard into most bends without the DSC firing. I love the way she handles usually, and i often enjoy 'driving' her, and I usually know where the limit is for the DSC and when it fires, I expect it. I know my car very well and where it's limits are. It's just that on these occasions I didn't expect it. D3 TDV6 HSE 2008 Buckingham Blue (current)

I have seen the DSC light flashing on a few occasions in the last eighteen months or so.
It mostly seems to happen on one particular wide sweeping right hand bend on a main road that I use reqularly and even in dry conditions.
I've heard that unequal tyre pressures on the front or a faulty wheel speed sensor can cause the light to come on.
My local specialists can't find anything wrong with the DSC and it doesn't happen often enough to really bother me.

Park on level ground bring your 4x4 display up and check that all 4 wheels are level on the display. If this is the case take it for a drive and keep an eye on the display. I suspect it may be a faulty level sensor on the NS rear. If it is a level sensor you will see a wheel drop on the display. Its a simple fix by fitting a new sensor.

Going a bit afster than my wife approves of, pulling a 2520kg van with 240kg on the hitch, on rough macadam, on a tight corner in the mountains, the DSC sometimes comes on for a few seconds.

As I understand if you switch your DSC off it doesn't fully switch off. Normally the first thing that DSC does is taking the power back and that is the only thing you switch off.
This helps you to keep the power on while in loose sand or snow. Roel

If you disable the DSC using the switch, is there any dash indication that it is "off"?
Does the DSC reset after ignition off, or do you need to reset it via the switch?
TIA,
Peter

I just went out to check, didn't have anything to do anyway. I boored watched 2 movies already and my releave only will show up in 4 hours.
If you switch off the dsc you get a message in the message centre and a orange warning triangle comes up with a arrow around it.
And it resets after you switch it ignition off. Roel

Only if you keep the car stable. The DSC will still engage even though its off (lets say 70% off)  especially if the car detects sideways movement. For example driving a rutted track that has a bend at the bottom of a steep climb. You need momentum to get up the climb but as the vehicle drives around the bend the DSC will engage and back off the power. The trick is to go a bit slower to reduce the yaw (I think thats what its called) and stay within the 70% off. In the Beginning there was nothing, which exploded.

I can't work out if you've had this issue with the trailer off.
I had some loose wires in my trailer electrics that caused all sorts of weird electrical gremlins in the car. Disconnected, mended the plug and all was fine. Had a similar thing when I forgot to take the traller board off a boat trailer and lowered into the water - but that was my own stupid fault
