I have the same problem on my '99 540. Once I turn on the fog lights, message goes away. However, the worst part is during the cold weather in Toronto, only one side lites up (either right or left). Dealer couldn't solve the problem. They only keep on changing new bulbs and this will work for about 2 weeks. They told me if they can measure the voltage or resistance error, they can replace the whole fog light assembly with no charge.
