Hi all.
I have a 2008 RRSPORT TDV8. The car is down on its bump stops and the compressor will not run. I have replaced the compressor and it will.still not operate. I have shorted out the relay connections and the pump runs but the suspension will not raise up. I am also getting the warning light for the dynamic response system up on the dash and this is red in colour. I am getting no other warnings.
I don't have access to a code reader at the moment so I do not no what codes it may be flagging up.
Does anyone have any suggestions as to what I can try. I have accesses the hidden menu and there are no faults listted.

Maybe check to see if the level sensors are broken?

I’m sure that somewhere is an ohm test to see if they work.

If they are like any other type of level sensor, I believe they are a potentiometer.

Probably not related to your issue, but just something to check.

Has the Dynamic Response system got enough fluid in it? I assume you've checked that. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed
