After doing all the work in tight space, I realized that the sensor could be reached via the "MBass" without removing any panel. The dealer would probably go thru the "MBass" to replace the sensor. Hats off to MB engineers. :bowdown:
If you don't believe me about the "MBass", watch the video. Video - TinyPic - Free Image Hosting, Photo Sharing & Video Hosting
Once your hand is inside, the sensor should be on the right side of the video with 2 wires attached to it. I measured the impedance at 69 degree F, I did some more measurement, the thermistor should cost $2 at your local electronic store.
