ABS light on

[Frir]

Hi guys, I installed a new LH front wheel bearing yst and tonite when i test drove it the ABS light stayed on. It's on at standstill with the engine running (I think this is normal yeah?) then it goes off momentarily once you start rolling but comes back on a good second later and stays on.

I'm thinking it's probably to do with the ABS reluctor ring on the new bearing not being 100% compatible. Yes, i put the bearing in the right way round with the black magnetic ring to the inside and was careful replacing the sensor in its hole after cleaning the tip.

The bearing wasn't an original ford one. I got it off ebay i think it is a brand called key parts prob made in China.

Any thoughts?

You may have disturbed the sensor wiring/connector/loom, check to make sure it's sound. Was the new or replacement hub for the same model..?? Not exactly sure but I think the Mk6 and Mk7 have different reluctor rings. Are you able to take a photo for us, might be sommink obvious to a knowledgeable chap.

Have you changed/replaced any tyres recently..??

hi, great forum given me loads of help. My abs/traction light came on a while back. I was just setting off steadily in the dry when my NSF abs started operating then stopped and the abs and traction light came on. anyhow mot is looming so plugged my forscan into the van ( if you havent got one i would really recommend it, i got a cheap ELM327 off ebay for £14 and the software is free for 2 months) the program threw up "no signal" on NSF sensor. i pulled out the sensor on the hub and there was a big gouge out of it, looked like a stone had got caught between the sensor and the actuator ring. I got a sensor from scrap yard and soldered it in and bingo, lights out!!! hope this helps someone some day. cheers steve
