Appears I will need complete replacement of air suspension system. I have decided to convert to coil springs. Do I need to purchase the complete conversion kit as package? I have seen some sites(4x4 sites) recommending simply medium coils and coils only. What other parts needed to do this switch?

 

What is wrong with your SLS? Would you rather keep it if you could get the parts alot cheaper?
If you do go for the conversion, a kit can be the easier way to go.
What is wrong with your truck/

take it to a shop with t-4 then we can talk try not to f--k yourself

 

So what is wong with your truck, they never need a complete replacement unless diagnoised by someone who didn't know what he was talking about?

Rear end of car has hit bump limit. I believe the bellows have leaked, it happened overnight when our temperatures hit single digits on Saturday and have stayed in teens and low 20's during the day. Could system be frozen? I took the car to a European import service and they gave diagnosis, but they do not specialize in Rovers.

 

The bags just don't start leaking and both drop as you described.
Your ECU is not allowing the bags to refill. I don't usually recommend this, but it worked on mine recently, assuming you have your radio code, unhook your battery for the day, then connect it, start the engine, close the door and see if it will reset.
If it doesn't, you will need to get it in and have a mechanic with either a test book or an Auto Logic scanner, test and rest the computer.

Hopefully that will work, because I just recently replaced the battery (two days before incident) after the car sat for nearly 5 months with a dead battery. Would changing to a new battery caused the reset not to take place?

 

Possibly.
It can't hurt to try .

FIXED!!! The fuse was blown for the SLS in fuse compartment under hood; replaced it myself.
