Hi all,
I have done some reading and couldn’t quite find what I was looking for. I have a MY61 5.0 SC Autobiography FFRR and it has given me the fault ‘Suspension Fault locked to Normal Height’
I plugged in my IID tool and got the following errors:

I have cleared the codes but the suspension fault comes back after starting and the others arrive after a short 5 mile drive.
The compressor blew its 60a fuse it has been replaced (due to check if it has blown again). New AMK suspension pump in June 2022
The car does not seem to drop height overnight.

Any guidance would be great
Thank in advance
Sebastian

If the compressor blew its 60A fuse then maybe the compressor is seized or the wiring to the compressor has chaffed and is shorting to ground or the compressor relay could be permanently on causing the compressor to run continuously. If the 60A fuse hasn't blown again then check for voltage at that fuse in case the 250A fuse in the engine bay fuse panel has blown. MY21.5 D350 Vogue SE Carpathian Grey

Thanks will check that sadly I’m at work over the weekend so will have to wait till Monday.
