Outside temperature reading
Yesterday morning when starting the car, I noticed that the outside temperature indicator was about right at 45 degrees F. I drove about 1 minute, stopped at a place for about 1-2 minutes, turning the car off.
When I re-started, the temperature reading was somewhere in the 60s! As I was driving, it gradually adjusted back down, 1 degree at a time, until it was "correct" again. It continued to function normally for the next 50 highway miles.
I was on my in for service at the time, so mentioned it to the service writer. The tech came out later for a further explanation and I gave it to him. He gave it a road test and could not make it happen. He also said the incident did not leave an error code, and started talking about how difficult intermittant problems usually are to diagnose and fix.
We agreed that the "worst case scenario" was probably replacing the sensor. In the mean time, I'm supposed to be watching for it to happen again, and that maybe it will leave a code eventually.
Does anyone have any ideas, or do you think this is just another one of the often-mentioned Mercedes gremlins?
Thanks in advance,
