Disco 2 SLS how to tell if bags or sensors?

Will be changing bags but wondering if it COULD be sensors as well?

Collapses one side in about 1 hour, but can stay up for days.

Having this with mine now went to use today and stuck raised. Considering springs. Cheaper than bags and sensors and sorted forever

More than likely the bags. They can start going porous over time and also develop leaks in cracks in the fold which can lead to them staying up for days but as soon as you move they can deflate.

Air is a good system. It sounds like you need to check the ride height sensors and recalibrate yours.

I do like the system but it seems abit of a weak part. It could go with no warning kind of thing. I thought it was sensors, as it's not sagging either end. Is it okay to drive? Not sure whether to do sensors or sensors and bags. Or just springs. Gana need a nanocom either way to reset it I suppose

Spring fail as well

Springs do not self level, been there done that with a saloon car, was unstable over 90 due to broken spring tails, had to drop a whole sports spring set on for towing and stability.

Was stable at 3 figure speeds but cost me over £200 for spring set and air adjustable shocks.

SLS is so much easier

If a spring breaks it is obvious and you just change the spring. Just one thing to worry about. They don't malfunction one day and OK the next.

+1
Plus you have the option to raise the back end between 30 and 40 mm at the flick of a switch on the dash and if you do end up bottoming out the chassis the system can automatically jack itself up to what's called the "extended" setting in an effort to get you out of trouble.
Coiled springs can't do that.
Frankly air is a great system, as people say "when it's working" and if you ask me it's quite easy to understand and therefore fix.
Under EU law (and we are still in the EU for the next week or so) the seven seater Disco should have been built on SLS, or so I believe.
If the vehicle was originally on springs then OK, but if it was built on air then why not preserve it rather than change it 'cos the bloke down the pub says it's crap?
OK, the compressor can be a bit pricey if it goes, but at the moment they can be had for about 100 quid second user or up to 350 for a new one.

I wouldn't worry about regulations for car production as there are some massively modified cars out there. Type approval doesn't mean the car can't be modified at a later date, as long as the insurance company is informed. Raising the back end might be useful for off-roading but few users do this. The one area where the air system is useful s the self --levelling when towing, but not essential. I don't miss all the noises when getting out of the car - hissing or compressor running. I didn't say it was crap, but for me I like to know that a complicated system isn't playing tricks with ride heights. If spring systems are so inferior then why are there loads of You-tube videos showing how to change over to springs - not just Land Rovers but for loads of makes? It is just a matter of choice.

it's not compulsory to do that cos the SLS has the so called "extended mode" which is automatic and it will raise by itself if the body is grabbing the soil

IMHO cos unfortunately those who want to make profit on conversion kits dont care about the vehicle... the choice is there for everyone to buy the vehicle with factory fitted springs but from my point of view it's a shame to bastardise a well enhanced vehicle by downgrading it to lower spec rather than fix it

Why spend £300 on a compressor for a 14 year old car when you won't even notice the difference? I don't consider my car bastardised because it drives the same as before. Each to their own.
