Big thanks for that informative feedback much appreciated.
Questions, is there a sensor in both front wheels or just one side that would be identified by plugging in?
Was wondering can I change this out myself if it’s just wheel off and bolts or is there more to it than that?
There is a sensor on each wheel so would need to identify which one is the culprit.
No reason that i am aware of that you cant change them at home as the system resets after a restart as long as the sensor sends the correct in paramiter signal. Conaero should be able to confirm that.
If you go into a 50mph plus long left hand bend and the fault triggers then its a fair chance that it is a left side hub that is at fault. Left rear in my case.
50pmh plus right hand bend and the fault triggers then probably the right side.
The weight of the car shifts to the opposite side your turning. Lessening the load on the on the side you are turning towards so the sensors on that side are more likely to show an incorrect speed reading compared to the other wheels if the bearing and sensor have slight play in them.
Sd / Leonardo and launch pro systems should will be able to tell which sensor from diagnostic.
A basic blue tooth and torque pro would reset the code on a 4200 and gransport. I cant remember if the generic fault code identified which corner it was.
