C240 2003 Cooling fan running constantly and loudly
My 2003 C240 sustained a front collision 6 months ago requiring new radiator etc.... Now fan runs very loudly and continually giving us the message warning about coolant and visit workshop. Took into local Mercedes dealer and they say not related to front end collision repair (not our fault, done at other person's insurance expense) but dealer claims ECU needs to be replaced at a cost of $1,700 ($1,300 for the part). Wondering if I should get a 2nd opinion about the need for this part replacement and relationship to that work done 6 months ago.
