L322 - air sus inactive (with a twist)

Have read many a thread about air sus inactive messages on L322 models. Mine has done it before but there is something a little different about it this time. It usually happens when the battery has been disconnected. This time it happened of a morning (cold night) but what is different is that it also had the orange LED light on the manual suspension height switch not light up. This has not happened before and I cannot see anything similar in other threads.

Any suggestions?

My 04 l322 does this when the battery is low. Cold mornings are typical
