RRS/Disco air suspn
Discussion
Odd one today and I'm not sure how prevalent it is on the Disco and L320.
My air suspn "height change inactive" warning pinged up a couple of times over the weekend. I mentally put this down to the possibility of a failing pump because TATDS.
On closer inspection today I could hear an air leak coming from the top of the reservoir which puzzled me as I was sure there isn't anything else up there apart from the tube shaped air tank itself.
I dropped it down to investigate further and once it was on the floor it became apparent that the reservoir had actually corroded through and the air leak is a pin-hole in the side.
Years of mud and crud trapped between the tank and the chassis rail have allowed rust to get hold and chomp away at the metal - thankfully it ate the reservoir and not the chassis. I've cleaned it all up and retreated the chassis area in readiness for the new reservoir.
The new tank should be here tomorrow (a smidge under £100 so no great hardship) but was wondering if this is common issue or just another LR oddity?

It’s a lump of metal that lives under the car.
As the years go by they do rust.
And eventually they will leak, I’ve heard of a few doing that over time.
I changed mine for a new one to allow brackets for underbody armour to go on but it was rusty and dented to hell and back but held air.
Good find though, an overworked compressor will fail.

I know, right? You'd think the quality powder coating would mean it would last longer... 
The new tank arrived today but too late for me to pluck up the motivation to get under the car so that's a job for tomorrow. Quite pleased to have caught this with a relatively simple and inexpensive fix.
Top tip for anyone else doing this task, wear protective goggles when removing the old tank. The amount of crud trapped up there was impressive. My safety specs meant it only went in my hair and left ear but you wouldn't want any of that in your eyeball.
