Question Discovery 2 - air suspension drops

Hi all, I am new to forum.
Asking for help straight away I am afraid!
I have a 52 plate discovery 2 with rear air suspension. over the past few weeks the suspension has been occasionally dropping when left.
Now it is happening pretty much every time its left for a period (overnight or in work) it is dropping on both sides, right down to the bump stops.
It does raise up again after about 5 mins of idleing.
I would guess if it dropped on 1 side I was looking at the suspension unit but both?
Am I correct in saying the compressor has had it? Are they repairable?

Also on a seperate issue RH side/tail lights keep blowing fuses, I know I need to check connectors and plugs etc but does anyone have an idea where I should start. It has a towing socket which is regularly used.

Thanks everyone!

You need to change the rear air springs.

I think Paddock's are doing them for about 80ish each.

I had the same problem on mine, changed both and everythings fine now.

Can't help with the electrics though.

Hi,
Without wishing to state the obvious, if it drops that quickly, then there is a leak, before you rush out and by new air units, check (or get someone to help) all the pipework connections from the compressor (which is located mid-way along the chassis) all the way back to the air 'springs' even the casing of the springs themselves as they can become porous with age.

Run the car for a few mins until the system is at normal height, then press the 'height raise button' allow it to reach full 'high' height, then, arm yourself with no less than some soapy water (diluted wash up liquid is fine) and a small paint brush, and apply to every connection you can find, there may just be a simple leak !!!

The reason I suggest this, is it would be a coincidence for both units to fail at precisly the same time, and you said the vehicle drops evenly on both sides !!

Converting to traditional springs is fine, but you will loose the self levelling capability . . . and if you carry heavy loads or tow anything like a horse box or caravan you will have a sagging rear and headlights that you can use for aircraft spotting !!!!

do the same on the valve block, found in the black box on the chassis under the passenger seat..

converting to springs introduces insurance issues and you may have to remove the two boot seats

Hiya Mate Got The Same Problem With My2001 Td5 If You Go To The Rear And Spray A Soapy Solution All Around Where The Air Suspension Bags And Connecting Pipes Are Leave It A Min Or Two And Have A Check. Wherever The Leak Is You'll See A Mass Of Bubbles Growing. I Can Also Hear A Hissing Sound Coming From Mine When It's Leaking ' Have A Look On Ebay You Can Get New Suspension Bags For 80ish Plus P+p.

Talking Re: Discovery 2 - air suspension drops

Hi, I've got a '99 TD5 and over this past year i've changed both air springs (11 months apart) and finaly this week, the compressor; after having the suspension fail to 'raise' with the internal switch. The airsprings were holding the pressure until I decided to investigate further to cure a slight imbalance right to left.

I disconected the feed from the compressor to the centre feed on the valve block(compressor located on underside of front passenger seat) and attached my garage compressor to attempt to see if I could pump the system - I had the engine running and the rear height raise switch selected (all doors closed) but could not get any joy. I decided to remove the comp with the intention to repair.

Splitting the comp to its compnent bits is pretty straight forward. Once removed from its mounting I simply applied a bit of wd40 to the 2 elongated securing screws on the comp motor. A gentle tap with a hammer on the end of the screw and they unscrewed pretty easily. You can now slide of the armature cover and see what state the commutator brushes and springs are in. In my instance, one of the brush springs (flat spring not coil) had rusted away due to moisture ingression - hence no motor to drive the comp - I manufactured another spring out of a bit of piano wire and after a little gentle rework put all back together. I tried to see if I was getting any power to the comp by reconnecting but no joy. I then ran out of time/light/patience and so ordered a new comp on the interweb (220 - sore!!!). Got local specialist to fit and clear codes - bob's yer uncle. Still have original which I intend to refurb and put on e-bay!

In summary, if both your bags are down at the same time you have a leak elsewhere. I suspect, that failing the soapy water leak check, the comp motor brush springs from my experience will be rusted. Replacing the comp is straight forward and a repair may also be possible with a bit of patience. Sorry its not a straight forward answer but like they say - its good to talk.........................
