The rear-end of my disco II is sagging. The car sat for nearly 5 months with no problems. I had to replace the battery of course to get it started.I drove it for a week and then this past saturday morning, the rear end was sagging. I started the car and the rear end did not self adjust. I pressed the rear-end adjustment button on the dash and that did not work. There was no sound indicating that it was working, or attempting to adjust height. Was could the problem be?

 

So your SLS is acting up. If you push the dash button, does the indicator light come on?
Are you trying to raise the rear suspension with the drivers door closed?
Can you hear the pump pumping when trying to raise the truck?

Indicator light comes on but only blinks, all the doors are closed and there is no sound from the pump when trying to raise rear end.

 

OK,
I would say it is time to get it to a shop that can read the SLS fault codes, like Rover's Test Book or and Auto Logic scanner.

Hoping to avoid that. Any chance a fuse?

 

No, your indicator light is coming on when you press the dash button so you have power.
I also have the SLS and as an old service manager I have to tell you, you don't have many options with this problem.
After you have a shop look at it, get back to me cause if you nedd parts, there are lots of on-line sites that will sell new and used parts alot cheaper then the dealer.
If you have any questions, call me.
