Wonky starter button

This is what happens when I want to start my 2003 BMW K1200GT after it has saw idle for a day or two, or sometimes just overnight.

Until today, the record was 21 button presses. Now the record stands at 33.

Once the engine is warm, it restarts readily on the first or second starter button push.

My dealer replaced this control cluster a few years ago. Then this problem developed. They refused to replace it again under warranty because they couldn't replicate the problem.
