I had to clean all the bird pooh off, so I took it to one of those stations where you can spray it yourself instead of an automated wash. As soon as I got back in the car and started it up to drive off last night, I got the lamp malfunction light. When I got home, I didn't notice any lamps that looked burned out anywhere. I ran through the checklist I found online today and it's something in the daytime running lights circuit. As soon as I flipped the headlight switch on the W210, the warning on the dash came back on. I guess I'll have to look more closely so I can figure out which light in that circuit is going out.

It's my first problem on my newly acquired 99 E Class, but at least it's a cheap one lol
