quick update
i checked both front and rear sensors and they were at least both still attached and looked normal.
Well today it failed the MOT on headlamp alignment aka 'pointing at the floor'
The dealer stated it was throwing an intermittent fault code, so in the end theyve had the front off to check the wiring! (after being sure the rest was within spec on the levelling sensors + the motors did work if vcds 'tested'
I have to say Im impressed and theyve found a break in the lh headlight loom
which meant on the self check when you first start them, it would fail and leave them pointing down.
I had visions of new motors/new lamps which had me a little scared as Im out of warranty and they are ££££££££
all sorted but not cheap at dealer rates!
but another years MOT sorted
, oh and i can see the road ahead again
