I’d go for the height sensor, if as you say you’ve tried different options, next is to go for the sensor side of things, they do wear out eventually, I would think that 75% plus of p38s still have the original ride height sensors.
recheck all connections again as a precaution.
one last thing, when you say you swapped valve blocks, was that the driver pack aswell ?
