Hi all

I know there are numerous threads on multiple errors and gearbox/abs faults but as with this car no 2 are ever the same. previously had the car going into limp mode with all the errors from the dpf clogging which i resolved.
following on from that the car starting to intermittently giver the abs parking and gearbox error and again go into limp mode. checking with diagbox and the gearbox points to the abs which in turn points to c1321 - front lh wheel sensor signal fault.

I can clear the faults and the car would run again fine until it would randomly do the same process all over again, with same error codes and faults.
this started to then get more and more often after removing codes so i decided to replace the lh wheel speed sensor.
the problem now is that where before i could drive and it would appear randomly after a day or week, now with the new part its pretty much withing 50 meters or after pulling off.
did I miss something, do I have to recalibrate or tell the car that this has been replaced?
one thing I did notice in diagbox is that after changing the part, in the error report it now shows 0kph where as the old one had a value.

any help would be greatly appreciated before i go insane with this car.

also this is a C4 Grand Picasso 2013 Diesel 1.6 HDi 110 auto egs

Check fuse box under bonnet for corrosion and battery condition (ECUs don't like low battery voltage)

Check and clean connection where sensor plugs in as a known issue.

I think about maybe some ground point could be corroded. Isn't there not something about some corrosion on the can wires or something on the abs module ?
