2005 clk 500 “coolant visit workshop”
I just recently cleaned the mass air flow sensor. Disconnected the battery ( did not hook up slave). It ran better then ever. Then out of the blur the coolant visit workshop and the radiator fan will not kick on.
My battery is 3 years old, 130 k alway gagage keep
Checked the washer fluid sensor, unplugged it and the check coolant came on the dash. plugged it back in coolant went off put the see coolant visit workshop was still there.
Any help would be greatly appreciated
