S500

First of all greetings to everyone. I'm a big Benz fan and started with a 1972 280 SE my dad gave me that lasted forever. I'd like to pick your brains out there and see if any of you have had problems similar to mine on my 2002 S500. It only has 46,000 miles but something wacky has been happening. The fun starts after I turn the headlights. The fan motor gets really loud, then the ESP and BAS lights come. If you turn off the ignition the light and motor stay on for about 5 seconds even after pulling the key out lol. I'm racking my brains trying to figure it out. It's runs great when it behaves though. Have any of you experienced this kind of problem? Thanks for any insight.

Fan on high is a symptom of a bad ecu.
Used parts are cheapest but You need to change 4 parts from the same donor car (eis key shifter and ecu ) if you are swapping used parts , otherwise used parts will not work since they are programmed to only work together
