I'm the same, the fix according to the interweb is to use a resistor across the led (a bit of a faff but you can buy led with one already built in) , but that effectively increases the power so that the "can bus" used by Bavaria can register it as a working bulb. Making it pointless to fit an LED (which is to save power on a boat).
Wonder if there's a way to adjust something on the panel circuit to accept a lower power?
Fortunately it's easy to check that all's working by going to the bow and looking up during the day and it'll be obvious at night.
