Audi A3/s3 traction control light

[Gianni]

Hey guys..

I spring cleaned my engine bay and my chassis the other day, when I restarted my car, everything was normal besides my traction light being on.
I turned off and restarted but my light remains on. ABS is working fine but traction control is not kicking in.

What could be the cause?? Are there sensors around the brakes that could have been damaged or dirty?

It could be your maf sensor, if you were in the bay, you may have knocked it, check that its all connected and secure....also worth scanning for fault codes as that will tell you what the problem is too.
