OK - I am not overly worried as ABS sensors are known to fail on the AllRoad. I am going to get one off eBay, as I did with the leveling sensor. It looks like an easy refit... But, I have also had advice that I should renew the whole bearing too.

Thoughts?

ps: All the lights on, as per my post from a few months back - abs/air suspension/ACC/start stop/ anti-skid...etc.

Hello Thomas,

Apologies, but I’ve lost the thread! - but seems you have a diagnosis of a faulty ABS sensor, or could it be a faulty signal to the ABS sensor. Not sure what you know that we don’t. 

Anyway, ABS sensors and EBay - yes of course if possibly you want to buy at the cheapest possible price for any old aftermarket one - if it works for any length of time. EBay is great too for say a quality Bosch one at a reasonable price. 

Re hub bearing renewal? Not sure on your model, but possibly applicable - the signal pulse to the sensor is via a built in magnet in the actual hub ( not the bearing as I understand it, so if you have a faulty signal from the hub, then you will need to replace the whole hub, not just the bearing. I’ve used Febi hubs to good effect.

If it were mine and I was going to that extent, then I would be renewing the probably-rusty back plate at the same time.

Kind regards,

Gareth. 

I have got it booked in to have the whole hub and sensor replaced on Monday.

Will advise.

Audi Allroad, the gift that keeps on taking! 🙂

 

 

Back plate? 

All done. Apparently the back plate was sound. Nice clear dash now. 

I'm meant to be driving to Cumbria, so good test run. 

 

 

 

Wow, you must be lucky Thomas. Sound back plate on a 7 year old model! 

Kind regards,

Gareth.
