Hi, my name is***** often than not this is typically going to be a faulty cooling fan assembly. Since repair work was recently done in the general area the connections to the cooling fan should be inspected first. The car should be connected to a Mercedes scan tool to check for cooling fan faults. The fan can also be tested with the scan tool.

Let me know if you have any questions.

Dear MartyIt would appear that this problem is intermittent.
After resetting plugs on the fan housing ... the problem went away but today it is back again.

I'm suspecting a bad cooling fan. I'd follow the recommendations I suggested previously for testing the fan.
