I just bought my E500, it's an 03, and whenever I come to a stop the light bar about the dash blinks lights and beeps, it's 2 red in front followed by the rest yellow, comes about half way through the light bar does anyone have any idea on what that means? Car runs smooth, everything checks out no codes or messages, no engine light. Doesn't make since to me. New to the E series. Used to own c series. But yeah it only happens when I come to a stop.

That sounds like you have parktronic which is the parking sensors in the front and rear of the car. Those use ultrasonic sensors in the front and rear bumper. The two red means there's an issue with the system. Could be a bad sensor or one has dirt on it. I'd clean them off and see if it just goes back to yellow which is normal. They only operate when the car is going less than 11 mph. If you had an MB Star or Xentry system, you can scan the subsystem and see exactly what the problem is. If it were a bad sensor, it'd tell you which sensor it was and you can just replace the single sensor. There's also a button by the shifter that will shut it off. I shut it off everytime I go through a car wash, otherwise the brushes causes it to go crazy.
