I like to recycle threads, and this seemed like as good a place as any.
I have a 2007 SLK 280. About 61,000 miles.
I was driving to work and got a "Message". The message was ONLY a picture of the temperature icon, with no accompanying text. I had been turning the A/C on and off periodically to clear inside windshield condensation.
According to the manual, that message indicates a malfunction in the fan.
I checked the coolant temperature on the MFD, and it was at about 90C, which I believe to be normal.
The message has not been available on three subsequent starts and short drives. Temperature has been solid on 90C. Goes there and stays there.
My mechanic tried to download codes, but none were available (this was not a full StarTech thing, just the handheld plug-it-in-under-the-dashboard thing).
Fan operates. Fan goes to higher speed when switching on the A/C. Temp stays consistent.
At this point, I'm thinking this incident was just a false-positive and everything is fine. I plan to just keep driving and monitoring the coolant temp pretty constantly. I'm not planning to change the fan until I get more indicators.
Any comments or advice would be very much appreciated.
