I am getting frustrated with this warning.
My defect. lamp warning comes one once in a while (once every two-three days) when I apply the brakes only.
a few days ago, I replaced all brake bulbs and it just did it again.
It's a 1997 W210 (E420), what else do I need to look for? The plastic cups that hold the bulbs seemed fine when I checked them. . .
