Traction Control Light On!

[edmong]

I have put my rear wheels to the front when I replaced the front.

I was driving today and the light just came on by itself, no wheel spin or anything. I got the wheels balanced on the front and when I did that I measured the tyre tread on the front and found that there was approx 1mm difference across the front two.

Im sure I have read somewhere before that because there is a small difference in tread depth the hub sensors think that one wheel is spinning faster than the other and so thinks there is a fault so the traction control light comes on.

Now when I swith the ignition off and back on there light goes out and is fine for a while but comes back on again.

What do you guy's think, am I right in thinking the above prob is it or could it be a knackered sensor? Warranty runs out at the end of October so I could do with sorting it out.

Also would vagcom through anything up to me?

Any help would be great

vagcom will confirm what's up

either sensor failure, dirty sensor (intermittent) or ABS unit failure.

probably the sensor

Thanks M0RK.

So my idea of the fault is not right then? I'll vagcom it tomor.

Right ran vagcom today and found this code:

00778 - Steering Angle Sensor (G85)
003 - Mechanical Failure

Spoke to SEAT today and they said they'll have it in to look at.

Its wierd thats this fault has only started since I put the back wheels and tyres to the front. Just out of curiosity where is this sensor?

 

[m0rk]

it's in the steering column.

you can 'zero' it using vagcom if you have a straight, flat piece of road you can drive on at about 10mph

I'm getting this intermmitently. A turn on and off of the ignition always clears it. You mention this could be a dirty sensor. Any ideas how you could go about cleaning it?

Cheers

i had this after hitting a pothole. procedure to clear it is on ross tech site

takes 2 mins, but as m0rk says, you need a bit of straight road

yep i get the same thing. however with mine it only happens when car is cold and under sudden braking. usually does it once and is fine after that. I would tell you all the fault code i get but dont have car for a few days!
