SLS Air suspension problem

Can some please advise me on my SLS problem?
I have a 2004 Land Rover Discovery; three years ago I had both air bags replaced.
For the past six month when I turn off my engine, I have been experiencing my offside rear dropping down to the bumstops,
This only happens within five to ten minutes after I have turned off the engine and never at any other time. I can restart my engine and the suspension re inflates to a normal level.
This problem only occurs about once a week or once a fortnight.
Due to this problem been intermittent my Land Rover garage are unable to find out the cause.
Has any one else experienced this problem or explain what the fault is?

Who's bags did you install 3 years ago?
What your describing is going to be either a air leak at the bag, bad height sensor or an internal ECU issue.
If you want more help, send me your number and I'll call you back.

After spending some time looking on the net, my idea was that I had a faulty height sensor.
But thought I would try and get some more information from people like you that know a great deal more about the Disco then I do.
Would the garage be able to check for any fault codes? Or is that not possible on my Disco 2?
So may be I should get the garage to first check the bags and then check to sensors and replace any faulty parts.
