Just got my 07 cl550 back from a friend after a few years and I’m trying to clear up some issues so hopefully you guys can help

-distronic error. Grill emblem has been replaced, he’s saying a bumper sensor is bad
-both taillights have the bulb/led out on the marker furthest towards the side doors and giving an error. He states that they are leds and the taillight must be replaced?
-engine fan runs wide open 90% of the time. No temp issues and cam sensors have been replaced per dealers (replace before doing the ecu as car thinks it’s overheating)
-1 out of 10 times the tweeter in the drivers door is full blast while everything else is off. Turning car off and back on fixes this back to normal.

Any insight on any of this?

Does the replaced grill have the right emblem? The one meant for Distronic?

Yes it does. I ordered new taillights and an ecu and the shop said that it may be a wiring problem or loose connector
