Weird noise TC light
Hi guys,

Lately i have been noticing that when turn from a stop and while releasing the clutch there is a weird Burring sound and the TC lights comes on for a millisecond and then everything goes back to normal. its something that started happening since a couple of months and want to know if its anything to worry about.

EDIT: Forgot to mention that it happens every once a while, not very frequent.

That's the traction control momentarily kicking in. It happens.

Could be one of the tires slipping before gripping or something?

or with DSC picking up a false feed as it sounds like system about to operate TC but not actually getting that far.

steering sensor alignment, wheel sensor failure possible issues. depends on age if has DSC Cheers

Hello,

Reviving this old post, Took it to an LR specialist and he hooked up a OBD2 scanner just to look at the live data from the speed sensors of all four wheels, 3 of them showed the same speed from pulling away except one which was stuck on 1, he just tapped the speed sensor a bit and it got fixed!

Now when pulling away there isn't any noise and no flashes, I hope this helps anyone with the same problem. 2014 Defender LXV

I had an issue once with a faulty sensor on my Disco2 which was giving a high reading. If you cleared the fault and drove off, the TC would immediately brake the FNS wheel hard, which was rather disturbing. It would eventually realise there was a fault and shut down the TC, ABS, and HDC (illuminating the three amigos). A new sensor fixed it.

It was the first (and so far only) time I've had a TC system try to kill me.

This is identical to what mine is doing. Diagnostics showed a wheel sensor. I’ll be ordering one and swapping out to see if it fixes it.
