Where's this popping noise coming from?
I have a 87 420 SEL with 150k on it. Lately I have begun to hear a muffled popping sound coming from the RR after I have braked at a stop sign. I also hear it after I have pulled the car into the garage, turned the key off and am walking out the garage door.
I haven’t looked under the car yet, but my suspicions are its brake related. Anyone else have any ideas where to focus on or had this problem before? Thanks |

[QUOTE=jriewer]I also hear it after I have pulled the car into the garage, turned the key off and am walking out the garage door.

I would be more suspicious of the exhaust system..ie..catalytic converter. Some kind of "heat soak" if you will in the exhaust system.

Mine does the same thing - 1990 420SEL. It is the exhaust system cooling - don't ask how I found this out!!!

Is this what Ive been hearing?
Sometimes a few seconds after coming to a full stop I will hear a muffled noise, almost like a door being shut. Cant locate the source. What is it?
