...go to member "JimF' website. He has listed a number of various issues dealing with MB cars. If you look under issue #18 he describes a situation similar to what you describe. He also lists a solution to the problem.

My W126 420SEL makes a similar sound. It happens mostly when it is cold and it doesn't happen all the time.

Hope this helps you.

Good luck.

PS: By the way, if your car is running hot, check out Jim's "cool harness." My daughter's 300TE was running hotter than I liked. I lower the coolant to water ratio to 45/55, added WaterWetter and installed a cool harness. Her 300TE has been running cool and smooth, even in the recent 100+ degree heat wave. check it out.
