DSC/ABS issues(air gap error)

[biggeek]

Hello

I have been trying to resolve an issue with my dsc for several months now

symptoms
abs kicking in very early
no traction on inclines
dsc light flashes when acceleration from standstill
brakes locking
skidding

codes states that there is a air gap on the right wheel sensor


actions so far
clear codes(wishful thinking)
cleaned sensor
swapped sensor to see if error follows sensor
brought new sensor
cleaned caliper pins as the breaking got really rough....but this was due to me leaving the clip off. :-[

i did a bit more research and saw an article which said a damage wheel bearing could be the cause....i had a flash back of me beating the hub back in to place when i did my cv boots....okay that must be it!

changed the front wheel bearing and still no joy :'(

any other suggestion???

The only thought I had was the axle nut has not been torqued down to 410nm maybe this is not holding everything in place.

Everytime i tried to fix this issue the car would work fine for 10-15 minutes of driving but then slowly get back to the bad breaking.

Please help I am at my wits end.

oh and the live data streaming shown on my c110 scanner doesn't seem to indicate a problem
