Disco 2 AIR COMPRESSOR

Had a major failure with my suspension compressor (piston rod snapped in half) Replaced with "new" compressor and now the ride height seems low. When I had the failure the air springs didn't go down and I was able to drive for some time. Any answers on the ride height ? Sensors are fairly new and genuine landrover.

You might need height calibration provided the compresor is working ... is the back rising if you push the ORM switch?

Thanks but went out today and it self levelled all by itself.
