On my 2011 RRS I had to replace the lower rubber bushings in the front lower suspension arms. On one 1 side I really problems getting the ball-joint loose and maybe over extended the height sensor on that side.

I now have 2 dtc's which are ABS and Height related. Cleared those but came back.

U0421-68
C1B00-64

It is possible to determine which sensors are involved (I worked on both front sides) ? Checked cables and mechanism from a visual point of view. No issues there. Cleared the ABS rotor and sensor also.

Currently I have warning (DSC and HDC are not working) appearing on my dashboard, which can be cleared with OK.

If HDC and DSC aren't working, that points to a wheel speed sensor or related wiring problem 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

Have you had a 4 wheel alignment carried out? I understand that if you have work done on the wishbone, it needs an alignment check/adjustment and if not done can throw up faults. You really need someone who knows these cars, preferably with a Hunter rig.

I did read the alignment statement after posting my question. It makes sense although I marked the positions of the alignment bolts and used these marks for alignment when installing the wishbones with replaced bushings.

Wiring seems fine and I checked if I damaged wiring (but I didn't). Warnings indeed only pop up above 50 km/h. After shutting down the car, these disappear.
