Coolant fan on 100% continously
I have a 2015 S 350 BLUETECH
Soon as I turn the ignition on and for approx 20 seconds after turning the ignition off my engine fan is running at 100%. My engine is not overheating but the TEMP GAUGE appears on my dash in amber.
It appears to be a wiring problem somewhere in he loom but the garage is unable to locate the wire?
Has anyone experienced this same issue and how was it resolved?

Mine did the same thing, my A/C required to be regassed, was told that after about 5 years the pressure dropped slightly and this was a safety measure ( the A/C was still working fine) but after the regassed you could feel the difference, and the fan was back to normal
