FTO AUSTRALIA

Ever since having the FTO my ABS light always remained on. I just thought it was some busted fuse or something but after recently looking under the car I saw that the front right wheel is missing something. I don't know the name but it's a circular part with lots of teeth like a cog, and basically the sensor therefore can't read the wheel spins which is causing the light to stay on.

I hope this kinda makes sense haha, what replacement part do I need to fix this problem?

Cheers

Someone has replaced the ABS hub you had with a non abs one if the sensor is missing and has put in a non ABS driveshaft instead of the ABS one thats supposed to be in there, thats your problem
