Vehicle shuts down upon cornering

[Dirty3]

Wonder if anyone out there has experienced this.
Recently took my D3 away for weekend after a long time off the road (me that is). Wife was driving (no, not her driving skills at question here!!) and as we took the on ramp to the freeway whilst hitting the corner at about 80km's the car decided it didn't like the situation and proceeded to present warning lights_ HDC/Stability control/Engine failure etc. Boings & Bongs, vehicle lowered and we slowed to the emergency lane. Turned car off, waited a few minutes then off we went no issue, till about 1/2 hour later this time going through roundabout. Went to dealer, they did a hard restart, all good for a few weeks until the other day did the same thing again going round a corner, not excessive speed, just normal driving. Had service yesterday, found quite a few message on computer. My LR dealer checked sensor on the gearbox, and software upgrade.
Anyone else had this issue? Vehicle is under extended LR warranty so not concerned but rather just curious.
Cheers,
Neil.

A couple of ideas. both regarding tires.

It could be possible that the DSC is working exactly as designed but:

1. The tyre pressures are not correct. If the pressure of only 1 tire is too low, it can cause the DSC to kick in very early due to the extra roll in the tire sidewall due to the low pressure. I have had this problem in the past. It goes away after re-inflating the tires to the correct pressure again.

2. Do you have original tires or have you replaced them with after market? I have heard stories about some cheaper tire brands causing the DSC to activate very early due to excessive sidewall flex. Have not experienced this first hand though.

Cheers,
Matt.

Forgot to say, that this does not explain why the other faults etc would occur at the same time. Sounds like there may be a faulty sensor somewhere that shows itself at those particular times. it is very common to have multiple unrelated faults show up when there is a fault with a sensor. This is apparently due to the interconnectedness of the different CPUs within the car.

Interestingly the problem only came up the same day that I had a new tyre fitted to front of vehicle. Same type of tyre and the other front tyre was only new 500km previous, so similar tread height. I did not check the tyre pressure to be honest as I would have thought the tyre mob would check all tyre pressures at the time, but will now check themI wonder if the LR dealer does this as part of service?

I should say that I have had General Grabber AT2's fitted for well over a year now and staked one 3 months ago but been off the road since till end of October. Had to replace the spare so got that done same day issue happened.
Replaced tyre with same GGAT2.
One reason put to me was that because vehicle had been sitting around for 3 months without regular driving is that battery may have gone off a little causing faults to occur. But have been driving solid for the past 3 weeks and no issues there.

get the alternator and its controlling stuff along with all of your earths checked....

funky voltages play merry hell with modern vehicles

It sound like the problem shows itself when going into a turn after some time driving, perhaps with no turns. As with the other posts, it could be a DSC or tyre thing, but in my mind, a wheel alignment.

If the steering wheel clockspring sends a signal that says the car is turning or not turning, and does that for any length of time, and the yaw sensor does not agree, plus the wheel rotation sensors see "wrong" answers, that usually causes warning lights and the suspension to drop to at least to access height rather than right down to the stops. You should also get messages saying DSC and HDC not available plus other scary unfun messages.

Then when you shut the engine down and restart, all is well for a while again.

Possible solution is a four wheel alignment and it can be the back wheels that are out of whack, not the front. Another indication is that the steering wheel is not at 12 O'Clock when going straight down the road.

Did the dealer re calibrate the steering sensor???
I have heard this can do funny things if the battery has been disconnected.

Check that the wiring loom behind the left front wheel hasn't come adrift from its mounting on the chassis and been chaffed by the tyre when turned hard left.

Are the brake lights working? Brake switch? or brake wiring goving similar symptoms to the blown bulb.

Never ... NEVER trust the "tyre mob" to do anything right !!!! checking pressures means "put 50 PSI in them all" ... the gorillas they employ at most tyre places can't even be trusted to put all your wheel nuts back on - I've had this happen to me !!! I always apply the ABC rule to tyre mobs Ask lots of questions Believe nothing they say & Check everytning yourself ...
I know it sounds like a case of "grumpy old man" syndrome but experience has taught me to be VERY wary of tyre places and their "highly" trained staff !!!

I had a similar problem with my D3 when the wheel alignment got out after a big bump on the beach one day.

The computer logged a steering wheel angle fault which caused the suspension to go into "OMG something broke" mode.

A simple wheel alignment sorted it out.

Old Salt has given some good advice here.

I recently purchased new set of tyres that have a maximum tyre pressure of 44psi. When I got home I checked the pressure and each wheel was pumped to 50 psi.

That's so true...
Whenever wheels come of one of our vehicles (servicing, new tyres) as soon as the vehicle gets home I run the torque wrench over the wheel nuts. My Holden ute is always under torqued, the D3 is always over torqued!
And, next morning I'll check the cold pressures on all the tyres.
In some cases I can almost hear the 'technician' saying 'I'm not real bright but I can lift heavy wheels...'

Thanks to all who have responded. Looks like there are several things to look at. Graeme, intserstingly the left front wheel was the one that had new tyre fitted. I'll have a look around under there this weekend.

Good idea to havea wheel alignment done also, so will get that investigated.
I wonder also if something was knocked or mis-aligned when the tyre was staked. It was on a reasonably heavy going weekend steep rocky tracks, mud, river crossings etc. 2 days later i'm out of action and car sat in driveway for near on 3 months. Only the occasional drive. Didn't even get to properly clean the underside of car after the trip.

A tyre fitting place can do the allignment but cannot reset the Steering Sensor. This I would be getting done first, either by a Stealer or independant LR specialist.
Where do you live?

[CaverD3]

And put into tight tolerance mode first as well for the alignment. You will need to take it back to them to have it put back to normal. Or dealer will do the lot.

[bbyer]

I just got my 3 back yesterday from the dealer and all is well. He redid the alignment - well reset a front tie rod and properly tightened the lock nut this time, I hope.

About a month ago, I noted that the the steering wheel rotated to about 10:00 O'Clock when driving in a straight line, previously it was at 12:00 O'Clock as normal.

Then when I went on the highway, after about 20 km of sort of straight road driving, no stopping, the Brake yellow light would illuminate, then the DSC light and then the suspension light plus a series of warning messages, not HDC, no DSC, and Air Suspension Lowering - to access height rather than the stops and the ride getting a bit bumpy. In town, because of the stop and go, and constant lane changing etc, the lower to the stops or lights going on condition did not manifest itself.

Now with the steering wheel back at 12:00 O'Clock, all is well again. Apparently the tie rod end locknut has loosened and things were on the move - and yes, the steering was not so good.

It was the steering wheel rotation sensor telling the computers that the 3 was turning, the yaw sensor saying no and the wheel rotation counters suggesting a straight line as well and the computers being programmed to release the air whenever these is any confusion about anything.

What bothers me is that I think the 3 is just too smart for itself. I know it is designed for the Autobahn to give Beamers something to chase, (3 ton brick outruns chick magnet again), but sometimes ... The good news is that by removing the F26E or the F35P fuse, I can now beat the computers for the most part. I amuse myself that I still have some control.

[~Rich~]

Exactly the car thinks it's cornering when it's not because the steering sensor is out of calibration. It has a hissy fit!

[jonesy63]

I once had this exact problem on my D3 - the dealer had the steering sensor out 180 degrees. Heading home from work on the M7, and I had the same error messages on the dash, accompanied by dropping to access height. (I would not call that "shutting down" though - the motor is still running).

Anyhow, that was yet another one of the misadventures from having repairs done by the trained monkeys at that dealership.

Hi Rich,
Live inner Melbourne suburbs. Dealer is nearby, so would get them to check first. have been having my cars serviced with these guys since 1998, so I have been happy with service over the years.

I'm wondering if we had this problem with our RRS - the DSC would keep kicking in when pushing even mildly into tight bends, and more so when the car was loaded. Granted the lower control arms needed replacing but the recurring code was related to the Yaw sensor and the tyres that came on the car were so cheap and dodgy no-one had ever heard of them.

Can Yaw sensors fail intermittently or be over sensitive somehow? Anyone know what it costs to replace it/them?
