Discovery 4 suspension fault

Hi all, I am new to this and not very good at the forums thing,
So hear goes, please help, today my disco came up with suspension fault on the dash, the back of the car goes up and normal but the front takes ages and gets there in the end, it will get to full hight and reach off road hight, I have checked the compressor and that seems fine I have changed the relay, it doesn’t seem to have any air leeks.. I am at a loss..

You need diagnostics mate or you'll be clutching at straws. See if there's anyone in the regional forum who wouldn't mind helping you out. Beer tokens/cake is usual form of payment for someone's time or find a good independent specialist to get any fault codes read.

I've got similar on my D3, intermittent suspension fault. I've got half an idea but am living with it until I can buy a GAP iid diagnostic kit next month and narrow it down.

You could guess at the front valve block as front is slow to raise but again, it's firing a parts shotgun and hoping for the best

Try the disco section mate.
