Welcome to the forum, @Paul A-C. The Bosch colour-coding is genuinely confusing the first time you see it, so let's decode what you're looking at.

The four white/blue lights are your battery level indicators working normally. Blue bars represent around 20% battery capacity each, white bars 10%, and once charge drops below 30% the bars shift to orange.

So four lit up means you're in good shape on charge. The red/orange bottom light is the one to pay attention to.

The bottom light is your assistance level indicator, where colours correspond to modes: green for Eco, blue for Tour, purple for eMTB, and red for Turbo.

So if that bottom light is showing red, you're most likely just running in Turbo mode, which is entirely normal. If it's showing orange rather than a clean red, that's a different story.

Orange on the assistance level light is a warning signal, usually advisory rather than critical. It comes on, for example, to warn you the battery has reached 30% remaining.

It can also go orange when your phone loses Bluetooth contact with the system. You mentioned this is a recent thing, so worth asking: have you changed which mode you usually ride in, or has your phone's Bluetooth connection to the Flow app been playing up? If the bike is still riding fine and there's no error code in the eBike Flow app, it's likely just an advisory.

A fully orange controller display indicates a non-critical error, and the eBike Flow app will give you more detail on what it is. If it is flashing orange rather than solid, that's when you'd want to get the dealer involved.
