Thread: D3 traction control applying front brake on corners

From my experiences,shot lower control arm bushes will cause this as will an out of calibration steering angle sensor. I'm sure other things can also be the culprit and others will come along with other ideas.

Check your tyre pressure first.

Different wear on tyres can also cause this. We replaced front tyres before rear tyres on our D3 and had to immediately replace the rears as well, even though they had about 5,000 wear left.

But yes, simple things first (tyre pressure and worn control arm bushes).

As you mention a shudder under acceleration maybe the second rather than the first.

Tyre pressures.
You may have a deflating tyre, I have had the 'Advanced Tyre Deflation Warning System' pick this up for me.

Lower control arm bushes.
You can get a fair bit of movement if these are worn out, wouldn't surprise me if the steering angle reading ends up out of whack under cornering load.
Vehicle system then thinks you have the wrong lock for the data from accelerometers and therefore are about to crash.

Out of interest, is it on the original suspension (struts in particular)?
Maybe the suspension has finally given up the ghost.

I've no experience on a D3, but in general if the wheel speed sensors get swapped left to right you get this symptom.

thanks for those replies,
slow down - her indoors says that also, but she wasn't in it.
I don't know about the age of the suspension struts, and will look at bushes
I will jack it up for a look.
it is due for a service so it will go to ricks as soon as I can book it in

Nah slow down is not the answer you should be able to chuck a well sorted disco around quite a lot before killjoy the computer interferes.

I'd be checking the inner rear bush for play. Use a large lever as it is not always obvious that the bush is no good (if the front one is in good nick it makes it hard to see the state of the rear one). Good luck

well, thanks again for the replies.
I went into the garage this morning and found the problem, left rear flat, tyre stuffed. I must have driven it flat for a while. it did seem to have a bit of a wander, but not as if a flat tyre, anyway all good now except I need another tyre.


and I would like to meet the bloke in land rover that designed the jack, the owners manual and the idiot that designed the spare tyre mount so that the towbar has to be removed to get the spare out!!!!!!!!!!!!
