08 nissan popping after car is killed and sitting in garage. can this still be brake booster?
We are not sure if your talking about the motor popping or the body. How long does it last ? How long have you heard this sound ?
If could be the exhaust system cooling down.
It could be the exhaust system cooling down, or the engine cooling down. It varies from car to car, outdoor temp, engine temp. A lot of variables, but all perfectly normal.
