These parts below were from Duckworths UK

Brake light switch XKB500110 UK POUNDS 18.00
speed sensors front LR013783 """""41.00 each
speed sensors rear SSB500102 """"77.00 each


These prices quoted yesterday from Duckworths UK...Oh and 20 UK pounds for P&P

Cheers

Hope they do a similar kit for the D3, but I'd most likely jsut buy all the parts - I travel around often enough just to hang onto them, plus I can be bothered driving the distance to pick up and return every time I would need them

Thanks, very helpful.

This is great idea, can I ask though, what happens when the following fail -

• speed sensor
• height sensor
• brake light switch

Also, the suspension bolts, are these prone to failing?
So far tyres have been the main issue for me, staked 2 at once last VIc desert trip. 8 tyre plugs in the sidewall held for 120 kms offroad though, that surprised me.

A dead wheel speed sensor disables all functions that rely on knowing how quickly or slowly a wheel is turning, ie HDC, TC, ABS, stability control and the suspenion ecu will lower the vehicle to about access height because of a brake system fault.

1 faulty height sensor disables fine-tuning of the suspension but 2 dead sensors will cause the vehicle to drop to the bump-stops.

The suspension bolts seem to randomly break which leaves the vehicle stranded on the spot. There is a possible link to a rear wheel alignment having been done and that bolt loosened but not replaced with a new one with thread locker or thread locker not applied to the retightened one and the bolt possibly working loose which allows it to flex and eventually snap.

A faulty brake light switch can cause a multitude of faults including a brake system fault which triggers the lowering of the suspension to its safe height.

Hi Redback,

What is the use/purpose of wheel speed sensors?

The Terrain Response will not work when they drop out.

Or the ABS, TC, HDC, DSC etc.....

The wheel speed sensor is a coil that measures an individual wheel speed by providing an electrical sine wave signal created as a toothed cog (usually part of the wheel hub) rotates past it. In most cars it forms part of the ABS system to detect wheel lock etc.. Had one go in my commodore last year. ABS fault light was the only indication. In our cars I imagine the signal from each wheel would be used for many system functions. ABS, HDC, Traction Control, Terrain Response etc... as mentioned above. As all these systems rely in some part on these little coil pick ups, I think this is a definite for the spares list. Would never have thought of it myself.
