It does not go down while sitting. Seems to be only when loaded or bumpy roads. One side does go down more than the other although they both lower. I have 107000 miles on Discovery and bags have not been changed. Thank you Disco Mike.

 

Any warning SLS lights on the dash?
Sounds like you just have a case of tired bags, which are not too expensive and can be replace in under an hour.

 

Mine stayed up while parked for days. Once I load her down or start driving on bumpy roads she will deflate both bags. Replaces both with Arnott and have had no problems since.

 

There are no SLS lights that come on. If I have a RAVE CD and given that I am fairly mechanical--is it possible for me to change them myself or should I have a local repair shop put them on? There are no Land Rover dealers for 200 miles. Thank you for your replies. I really appreciate them.

Yes super easy. Just use jack stands to be safe.

Thanks guys for all of your assistance. I replaced the rear air spring assembly on both sides this week from products from Arnott and appears the problem is solved. Great help from this forum.
