Traction Control Light Coming On From Standstill

Hello All,

Had a strange one this morning, drove to work which is about 17 miles from home, pulled up at some traffic lights and from standstill when changing into 1st gear to pull away the TC light flickered on briefly and the audible sound of the TC also. I can recollect that I had this happen once before, though didn't notice the TC light on at the time, and thought it sounded like a gear box noise.

Any thoughts would be appreciated, before I mention it to my dealer.

Cheers

Keith

I also get that occasionally, but without the light coming on. I think it's the system being armed ready.

Mine is down to the CVs getting a bit worn. There's a post from a while back where mine was coming on when going around corners and the CV joint whining. The joint was a bit dry, so some oil later and cured it. I think the vibration was enough to cause the TC to think the wheels were too far out of sync. Craig Rogers

Hi Craig,

Just been trawling other LR forums and found this,

http://www.aulro.com/afvb/90-110-130-defen...ise-2.html

Someone on here suggested, tapping the sensors home with a small hammer and this cured it,

Think I will see how it progresses and if need be have it looked at, as its still under warranty

Cheers for the link, but them sensors are pretty fragile, not sure I'd start whacking them. Craig Rogers

My sentiment also, will let the dealer break them

I assume the sensors work the same as most automotive movement sensors (like the Crank sensor on a Flywheel).

They are magnetic and sense the spinning rate of the "teeth" of whatever is spinning. I supose it's easy to get some dirt in there (or even a small piece of metal) that can throw the readings.

I remember back in my Mini racing days when I couldn't get the car to start after we'd changed the clutch in a rush in the paddock.

We had slightly bent the sensor putting the clutch assembly back in which meant the firing was out enough not to be able to start the car. Craig Rogers

Are you sure you're not revving it in 4500 and dumping the clutch? That might make the TC come on

See very last post. Sensors can be easily extracted cleaned and put back in. If you're under warranty and can live with it until they can look at it let them sort it. Mine was undriveable at one stage. You can also get round it by pulling the 30 amp fuse under the driver's seat if it gets too much.

Thanks for all your help / info If it was out of warranty I would certainly have a look myself, and now I know what to check and look for

Cheers
