We have a CF (26t) that is in for the 10th time with faulty suspension .
Sometimes it’s like a hot rod other times its leaning to the left/right !
Daf have allegedly replaced all sensors anyone had this ■■?
Boss has told them not to give back till they can’t guarantee it’s working and will hire truck and bill it to them
What year is the truck?
I had a 2005 XF where the susension would do what it wanted, never did the left/right thing though, but, it would go to the top and bottom limits on its own
Our CF unit has got to go back in for a ‘part recall’'…something to do with a brake valve or something to do with the brakes anyway 
And some worry about rusty bumpers 
They are 59 plates ,
we have 6 of them but only this one does it , very weird
the problem on mine was a dodgy earth in the main wiring loom down the chassis, what i did was to cut the earth to both rear lamp units and earth them both direct to the chassis
before that, there were various recurring electrical problems, after i did that, it seemingly cured them all
Sounds as though it may be a height sensor or the wiring to it …more so if it has 2 height sensors
have they calibrated new sensors ? i have had problems with ecas ecu multiplug water ingress and tracking across terminals causing strange things
Spoke to the guys who do our trailer and the recon its a wiring fault ,alledgely DAF wiring is terrible its far to tightly packed in the loom and with very little give .
if a wiring issue ,there should be an associated fault code .though the wiring is simple to check with a multimeter
