ABS sensors issue

[Paul Roe]

I got a warning message about the ABS sensor and tyre pressure so I need to get the sensors replaced however when the error pops up I also get an error about the ACC forward sensor not working and sometimes I even get an error about the stop start system not working. So is this more than just an ABS sensor? I am currently in the Scottish islands and don't get home for another week and the MOT is then due so will it fail the MOT with all these faults showing?

I don’t have acc but tyre pressure, stop start and abs warning all come on when the abs sensor goes. The sensors measure wheel speed so it wouldn’t surprise me if somehow related to acc.
I think it would be an MOT fail but it’s also a very quick / easy repair - if you can change a wheel you can do it yourself.

Is it worth changing all 4 sensors or is it just the rear ones that fail?

 

[Louis II]

I just changed the one that failed but you need to be able to identify which one so if the van is telling you it’s the rear I’d be inclined to change both for ease. On my t5.1 I can use Carista to identify the specific sensor - not sure if Carista works on newer vans.

Yes the sensor will bring up all of those faults, just replace the one that is messaged to you.
