    It is everything to do with this. There is no forum at all without the advertising revenue that is entirely predicated on a G-rating (as defined by Google et al) and member subscriptions.

    Let’s please keep this thread on topic.

    D4 Rollover

    The idea that HDC is available with engine off doesn’t sound correct to me and is the first I’ve heard of it. I certainly wouldn’t be relying on that.

    I do agree re less stability when at higher than off-road height and always try to have the height as low as practical for the terrain.

    I have been in a stall situation a couple of times with a loss of traction on very steep slopes. Holding the vehicle with the foot brake wasn’t difficult as far as I remember while re-starting.

    I reckon slipping into that gully would have been enough to initiate a roll.

    I don’t fully understand how the engine would stall with an auto box and torque converter.
    He said that the engine turned itself off to protect the transmission once the car started rolling backwards in a forward gear. Not the best way for the car to protect itself under the circumstances!

    Good points about the HDC. I'd never thought of that as a safety backup if something went wrong with the engine or transmission on such a steep slope.

    He said that the EPB should automatically activate but it doesn't on my D4 or L405. The EPB auto activates on my 2017 DS though, when the engine is turned off or the transmission is put in Park.

    It's virtue signalling, and hopefully it will pass. Meantime, we have to put up with it here for Inc's sake. Wish it wasn't the case. I am sick of being constrained by people who have not earned my respect. From what I know of you, Chris, I would imagine you feel the same. **** 'em. (Swear filter test).

    Does this actually happen?Definitely didn't in the D2 i had.

    Good points about the HDC. I'd never thought of that as a safety backup if something went wrong with the engine or transmission on such a steep slope.

    Will HDC definitely operate if the vehicle engine is not running?

    He said that the EPB should automatically activate but it doesn't on my D4 or L405. The EPB auto activates on my 2017 DS though, when the engine is turned off or the transmission is put in Park.

    Only does on later D4's,mine doesn't.

    Lots of questions,we will probably never find out what exactly did happen.

    The main thing is no one was injured,but it does show how easily these thing can and do happen.

    Guilty as charged. My D4, my rollover, something not on the bucket list ticked off, but I walked away with a few “non AULRO permitted” bleeps and few bruises.
    To clarify a few things written above:
    Height setting and loaded to hilt....irrelevant to the cause of the rollover and not quite correct.
    The track was an uphill climb, loss of traction, stalling occurred.
    The rolling backwards (the part that really concerns me, as I’m pretty sure my foot was planted on the brakes - which is also needed to restart a stalled vehicle) caused the vehicle to barrel roll off the track (as the track edge disappeared down the embankment). The vehicle did not roll on the track, it rolled backwards down the track, off the edge, and then barrel rolled.
    HDC working in reverse with engine off / auto park brake
    HDC in reverse definitely works when the engine is running, I have used this a few times. HDC was not engaged, although comment has been made about it working with the engine off...I’m not sure. Lesson learned though...tough steep climbs, maybe engage HDC.
    Auto park brake - this did not occur, probably as it is a feature added / removed before / after my model.
    Thanks for the wishes, sorry for the swearing ;-)
    A few lessons learned, ultimately line was about 10cms wrong, and I walked away. Glad it was in a D4.

    Hi Simm. Very sorry to see you D4 on its side. Mate I have had a situation where my vehicle stalled and rolled back only a foot or so and by the time I bit the brake she slid a bit before the brakes stopped her (very steep.climb). I wonder if yours may have slid under brakes off the side? Ie the ABS did not allow the tyres to bite into the dirt and kept releasing slightly tbe pressure on the rotors before lock up.

    Cheers

    It looked like a wonderful and sensible trip with friends, I am so glad you are OK, and that your insurance paid out. Keep on keeping on!
