My '08 C220 was recently in the local Mercedes dealership where they carried out an air-con refresh. Since collecting the car, I've noticed that it intermittently makes a gurgling noise that sounds like it's coming from somewhere around the center console. The best way I can describe it is that it's very similar to the noise made when the last bit of water goes down the plug hole when emptying a sink or bath. Sometimes it happens immediately after starting the engine, while other times it happens mid-journey, and only seems to happen once per journey. It's not particularly loud, but it is loud enough to be heard over the radio when at low volume. It doesn't last very long, maybe 1-2 seconds at most. The noise happens regardless of whether the air-con is on or off.
I've had the car a few weeks now and it definitely wasn't making this noise prior to the visit to Mercedes.
Any ideas?
