ABS light on

[citori]

Hello everyone.

I have a 2011 octavia estate, 1.6 diesel DSG.

The ABS light came on a few days ago and now comes on every time the car  goes over about 10mph or so.

I took it to a German car specialist to look at it and the said it was the rear wheel ABS sensor. One was duly purchased and fitted but it hasn't fixed the problem.  :no:

They now tell me that the rear hub has to be replaced as it may be damaged. What? I didn't think the toothed part of the hub for the ABS could get "damaged". Dirty maybe, but not damaged.

Anybody heard or experienced this before? I'm not totally hopeless when it comes to cars, is it something you can tackle yourself? the car has disks on the rear BTW.

Thanks in advance.

Water gets in and they rust causing them to eventually fail.

2011 seems a bit young for a rusty reluctor ring but it might have been damaged. Means a new hub unfortunately.
