Outdoor Temp Stuck on 68 degrees
On a 2011 E550. p/n 007-542-13-18 "Temperature Sensor." $14 A pointy black plastic thing held in a bracket. No idea where located, but they said it was a quick fix. A blog years ago had: "Look under the front of the car on the driver's side, you should see a black thing protruding from a lower body panel. That is the sensor and it can become unplugged, loose, or go bad. I'd check the connection or tighten it first and if that doesn't help replace it." Don't know if it applies now.
