Hey. 
So I cut out the brake disc shield which had rotted away from the bolts causing some major noise issues, on next drive the ABS/ESP/TPMS lights all illuminated. Presumed that I had damaged the speed sensor whilst taking the shield out so bought and fitted a new one. But the problem has stayed. There’s no code displayed on the obd sensor to clear so I’m a bit confused as to why they are still present. It’s surely to do with the dust shield removal? Or just coincidence? 

Could be related but only a one on four chance that it would have been that wheel speed sensor, you really need to check with something like VCDS where you can look at live data and see any intermittent bad signals.

 

You dont need to delete the fault codes for the dash lights to go out but if a sensor is still bad they will come on again on each start up or during the journey if intermittent.

I just presumed that it had to be something related to the dust shield removal as it was then the issues started. 

It could well be if you had to give it the good news with a hammer and chisel.

 

Mine failed after clipping a kerb, what can happen is that the ferrite magnet enclosed in the plastic casing fractures and the signal generated is significantly reduced, did you replace it with a genuine part?

 

I fitted the cheapest Ali-Express pattern parts, they were less than an Euro each, the one fitted works fine but I had low expectations, turned out it was worth the punt.

 

At least with VCDS or similar you would know if the fault is with that wheel sensor, possibly the connector.

Bought a Hella speed sensor so not oem but reliable.
