So...

...that went well...🙄

Replaced the ABS sensor this morning, and now I've got FOUR warning lights! ABS, ESC, steering and TPMS...

OBDeleven is still saying right hand front ABS sensor.

When I took the old one out, I could see a few fine scratches on the tip, and peering down the hole it came out of, I could see quite a lot of flaky rust, so I scraped that off with a small screwdriver, whilst slowly turning the hub. I also noticed what seemed like a number of small, black plastic "flaps" on the vertical face just outboard of it. No idea what that face is?

Ah! Just looking on YouTube, and what I thought were plastic flaps, are probably actually bits of the magnetic ring on the bearing!

(That's a Karoq, but I think it looks very similar to our Kodiaq)!

If you disconnected battery the steering and esc will come on until you turn full left and full right plus a short drive. Looks like you may have to remove bearing and clean or replace.

I've had a rusting bearing wreck an ABS wheel sensor, it was on my 2011 Audi S4, for a few years prior to this failure, I could hear a slight scraping noise, initially only using that car after it had been left unused for a few weeks, then after maybe a mile or so, that noise stopped. Then it never stopped - then when driving it out of the garage to go for its MOT, the ABS etc lights came on, game over!

So, what I discovered is, that all the bigger VW Group cars do not have any protection built in for the, at least, front, ABS sensor from road grit etc - small cars like Polo/Fabia/Ibiza have a plastic shroud to help avoid this to an extent. What does help, I discovered, is that if the wheel bearings "bleed" out a very small amount of the oil in the wheel bearings, hub and bearing inner face rusting is not normally an issue, if the wheel bearings do not "bleed" out any of the oil from the wheel bearing grease, then hub inner face and bearing face rusting can be an issue, especially when combined with only using that car periodically in winter weather.

After getting the ABS sensor replaced by the MOT garage, I removed the new ABS sensor, cleaned its hole in the hub carrier out, then used a piece of dowelling cut at what I thought was a suitable angle and forced that down to contact the inner face of the wheel bearing - then rotated the wheel a few times in both directions, then applied lots of ceramic grease to the ABS sensor and refitted it.

I examined the new ABS only a few days/miles after my MOT garage had replaced it, and it too had started to show signs of scoring - from contacting the rust on the bearing inner surface, so I'd expect that that new ABS sensor would have only lasted a few thousand miles if I had not cleaned up the inner face of the bearing.

Getting access to that inner face to do a proper job on your car will involve removing the drive shaft - if you want to avoid a repeat of this issue.

As said, you need to drive the car to clear the stored faults in some of the controllers even although you have removed the fault and cleared the ABS controller fault code.
