What makes a soft clicking noise after shutting off the car?
Welcome to the GLAowners forum. This has come up before and consensus was it was cat converters under the chassis cooling down. A similar question came up on a soft motor noise from the engine compartment long after shutdown, which pointed to a pump circulating fluid to cool the turbo, IIRC.
