You remove the 20A fuse under the bonnet. Then see what corner is down in the morning

Hi

One of the first things is to put ur suspension height into off road setting

Then remove fuse F26 that’s in the engine bay , then leave over night , it’s stops it self levelling

Look in the morning to see where it’s dropped , if the front is leaking it will drop at that corner

Also if u have a search there’s a lot of info but plenty to always help along the way Thumbs Up

Hi

Would be very surprised if both front bags have gone, u can recondition the front valve block by replacing the internal the O rings inside , or replace it with a new one if u prefer to do so

https://www.ebay.co.uk/itm/Discovery-Air-S...m570.l1313

When u take it apart u can sometimes find white dust, which is an indication that the compressors incandescent dryer material regs replacing

This is for the hitachi air compressor ,

https://www.ebay.co.uk/itm/281240594732?ss...noapp=true

There’s also this video showing U how to replace them , done by the legend Mr @bodsy

yes always a good first (and common issue) to replace the seals in the front valve block.

Morning all...

A little bit of an update, replaced the seals in the front valve block not too dusty in the block, but its still acting like a nodding donkey, with the front end dropping, both sides are on the deck even with the self levelling fuse out....

Any thoughts on what next to try and check....



Cheers

Dave

I guess you could mix a bit of washing up liquid and bit of water to make leak finding/bubble mixture to see if the top connections of the strut are leaking. (once fully pumped up to off road) and anywhere else on the strut.
May as well test the front valve connections too.


If that don't find anything, I guess a new front block is a lot easier/cheaper to replace than front struts!

Are you confident you pulled the correct suspension fuse? It behaved slightly differently did it?
