Seriously? Another Inskip embarrassment.

[Milton477]

Go the D2, he must be doing something right.
I got bogged at Inskip Point (https://www.facebook.com/igotboggedatinskippoint/videos/1333895270049499/?hc_ref=ARQVvlst8jgchxIeKAJhA6RuYMNP97be5kLCNauebr hjlfyLLe5kazKsVsLv-VS9MDs&fref=nf)

[Pub247]

that was frustrating to watch

[geoffmc]

We were there yesterday on our way to Fraser and yes the sand was soft, however 20psi, sand mode, suspension up and DSC off, the Disco sailed through. It looked as though his tyres were up and the suspension was at normal height.

The V8 sounded good though.

[DiscoJeffster]

Pub247, you were very polite. That’s was ridiculous and embarrassing.

[LRD414]

It's always tyre pressure more than anything else but correct technique comes into it as well.

Anyway, as an antidote, my experience on Stockton beach the other day ..... deployed the classic sand self-recovery at the southern beach entry/exit. Had been on 20psi without issue but the really soft chopped up stuff near the track entry proved problematic and I sunk down to near mid-wheel going across wheel ruts. A small group of Toyota owners perked up like Meerkats, looked on and seemed to me to be quite keen for the D4 to be needing a recovery. Sadly for them I didn't follow that script. Dropped pressure to 14psi, put it in Rock Crawl, rocked backwards and forwards twice, applied some steering left/right and then drove out and up to the track. They then had a few issues getting going themselves with much revving and sand rooster tails.

EDIT - Comment taken from elsewhere:
"The black Discovery had a sway bar break on Fraser Island and damaged a suspension sensor causing the suspension to drop to the bump stops. It could still drive but was dragging."

That wouldn't help [bighmmm].

Having driven a none CDL V8 D2 on Fraser ...... I would have agreed it has to be tire pressure.... (before I saw the edit) I never got close to getting stuck - and I'm Victorian!... we don't get to play in sand that much [biggrin] [bigwhistle]

Come on what about your sand pit[bigwhistle]

[Tombie]

A lesson in safe snatch recovery is definitely needed though!

[goingbush]

you can't use snatch straps again and again , they need time to recover .

Im astounded that KERR ropes have not replaced snatch straps, they are far safer , stronger , and need no recovery time .

Mightaswell have a gander at this while were here

[northiam]

Looking closer at the vid appears the suspension is rising and falling or maybe its sitting on its belly?

It does not appear to be on the bump stops to me ?

The comments say the suspension lowered due to height sensor failure so if one fails the LR design strategy is to lower to the bump stops?

Planning a drive along stockton beach with D4 factory 20inch wheels wish me luck!!

If suspension fails like above will my new gaptool save the day?

Often it just goes back to Onroad Height and gives a fault indication that Onroad Height Only is available - seems that is the case in that vid.

Here is another from Inskip Point - taken from the 4x4 Earth Forum. I am not a Facebook Member and can watch it so you should be able too. When it asks you to login or join just hit the Not Now option.


Always use rated recovery points - I got bogged at Inskip Point (https://www.facebook.com/igotboggedatinskippoint/videos/1333769193395440/)

[Tombie]

He claims it was on bump stops in my post.. but it looks at least to be at standard height.

He’s getting defensive when I commented the driving lacked a little.

[trout1105]

I watched a few minuets and couldn't bring myself to watch any more it was far too painful to watch.
Old mate in the tricked up D3 appears to be "Clueless" from what I could see he wasn't applying any drive to he wheels until he was nearly stationary after the snatch.
Tyre pressures were probably too high and it looks like he hasn't put the truck in extended mode either which is most likely why he got into strife in the first place.
The D2 did a great job But the driver should have told the person he was trying to snatch to lower his tyre pressures and use extended mode.
He/she should also have had a word about the D3 drivers technique when being snatched as well and it would have been a simple recovery instead of what occurred.
Just another perfect example of someone with a 4WD that hasn't any idea how to drive one correctly[bigwhistle]

[Milton477]

Here I was thinking that this was concrete proof that D2s are much better in sand than D more than 2s.[bigsmile1]

I have NO experience driving D3's or D4's But my D2a just LOVES "frolicking" about in sand [bigrolf][thumbsupbig]

[DiscoMick]

When being snatched he didn't accelerate until he had stopped - why? Even if a sensor had failed and the D3 had dropped, it didn't appear to be dragging its bum in the sand either. Was the D3 at normal on-road height?
The D2 didn't seem to be having any problems in the same sand. If anything, the D2 was flattening the tracks for the D3.

[iannicki]

I have previously only had to snatch or be snatched in mud and not sand, so this is a genuine question.

The run up and speed of the snatch looked quite aggressive to me. Do those who know about these things have any comments?

[discorevy]

D2 driver going too fast , clueless d4 driver should have been around 1/3 constant throttle as the slack was taken up , the strap had lost all its stored energy by the time d4 had applied throttle , people will argue this but d2 has a natural weight and tyre profile advantage over d3/4 on sand , saying that , correct tyre pressure and a clued driver will have no issues, in a previous life I drove / owned a Mercedes 911 4wd bus through sand dunes , along beaches etc , was just under 14 tonnes loaded , no problem thankfully, now I just drive the local volunteer fire truck [bigsad]

Looks correct to me, but you can only do it the once . twice at most, after that the strap needs half an hour to contract back into its relaxed length. Which is why the third and fourth 'snatch' have no stretch ..... just bang .

[martnH]

The owner of that D3 said the sensor failed so the D3 was on road height

Was a bit too aggressive on 2,3,4....

Other than that, you’re spot on...

Amusingly, if they had laid out their maxtrax (sitting up on the roof) to ramp it up and get going they would have done a lot better.

Would a diagnostic tool allow a person to disable that sensor or put in an offset to allow the suspension to raise?

[northiam]

Would have thought LR code program writers could have included.

suspension initiates/allows extended mode in the event of height sensor fail when in low range, for example

Curious about about what front recovery point the D3 was using?

If its the factory one it was sure taken some punishment.

IIDTool can!

Is it possible to manually control the air suspension? - Gap Diagnostic (http://www.gap-diagnostic.com/faq-items/how-to-manually-control-the-air-suspension/)

Stop for a second and think about that... [emoji41]

How, with a failed sensor, does it know? [emoji56]

It wouldn’t know when to stop [emoji12]

[trout1105]

I just hope that Old Mate in the D2 wasn't using his own snatch strap, This is exactly why I refuse to use my own strap on someone else's truck.

If only one sensor or maybe two on one axle are out of range,

you select low range.

it enables susp extended mode! [bigsmile1]

[Tombie]

Yes. I get that bit..

But if it doesn’t have a working sensor it can’t find extended height!
And would therefore extend to mechanical failure!

The sensor is needed to let the vehicle know how high that corner is and in any scenario requires it.

The only way to avoid this is manual control either via a manual inflation device or using IID and manually lifting and stopping yourself (still potentially able to over inflate/extend).

See what I’m saying [emoji846]

[RANDLOVER]

Thanks Disco-Jeffster that's great info on the GAP diagnostic tool, I'll have to get one of those. I had EAS trouble and managed to inflate the bags by bridging power to the compressor and valve blocks, but might've damaged the blocks as they require pulsed power not the full 12v for long periods, all good now though. I can a-test to GAP's warning about driving at extended height, it was like being in a rodeo!

The compressor could supply the same regulated pressure to all four corners in this event and disregard the height sensors [bigsmile1]

Another little trick, when you are stuck on your belly in sand (or anything else), is to lower the suspension and then the vehicle detects it is stuck and goes into extended mode. This is another 25mm higher than offroad mode, then if you hold your foot on the brake and pushing your height up lever for 30 seconds, it will go into super-extended mode, another 25mm again.

I have a piece of timber, cut to the correct length, I lower the car onto (on the chassis) to simulate this in the carport to get into super-extended mode, to wash the vehicle after a day at the beach.

I bought LLAMS .... All of the above at the turn of the dial :-)

I was at the 'Desert' on Moreton Island some years ago and came across three cars completely bogged to their bellies. Is was very hot and very dry, and the place does get super soft and it is easy to get bogged. I know that 'cause I did it myself once at 18 psi on Pirelli Scorpion ATRs in very similar conditions.


However, these guys were just clueless .... Jeep GC at the front, Prado trying to recover it and a LC100 at the back trying to recover both at the same time. They all would have tyre pressures closer to road rates I recon, as there was very little evidence of bagging (I looked closely once they got dug out). I saw they had Maxtrax and I asked how the panels had failed to help them....as that's exactly what I used to get myself out. That was the first time I used them and was very impressed with how easy they were to use. Then they showed me the Trax .... completely trashed .... they had completely burned the knobs off the panels.

To your point .... I handed them my shovel ..... LOL!!! No chance they were using my MaxTrax......
