tcs light

[iom]

yesterday after going fast, w.o tcs it still stays on. tried disconnecting battery if it were to be just a faulty button. what else could it indicate than faulty maf? i've got brand new bosch maf like a month ago and got rid of the light then.

You need to scan it for codes mate. Could be MAF again or something else. Without fault codes you're just guessing.

Does your check engine light work or has someone covered/removed it? It's unusual to just get a tcs light without either a engine or ABS light as well.

Weird. Possible that you have a fault with the switch then.

it resets if i disconnect the battery, turns on same second when i start moving

have you scanned ABS? does the ABS work?

haven't done a scan on them, abs works fine

Oh right, not the switch then.

I agree with what andy says, could be related to the abs as they share the same wheel sensors. Does the ABS light come on and go out again as it should? Lot's of times people put tape over the lights.

Yeah it's a weird one. The two common causes for the traction light is MAF and wheel speed sensors, however the first usually brings up an engine light, and the second an ABS light. Judging by the fact it only happens when you move, then i'd definitely say wheel speed sensors.

I had that light on when the steering angle sensor failed

Yes that's a good point, if you have ESP as well as TCS then steering angle sensor is a very good shout.

Looks like a date with someone with VCDS is on the cards.

agreed really need to scan it, - for example do we know at the moment if this is TCS or ESP? if its TCS then the comments relating to ESP sensors wont apply.
