Funny suspension(?) noise...

[Vroom]

Got a 2013 C-Class facelift that came back from a service and it's first MOT about 2 weeks ago.

The last couple of days whenever I go over a bump or a speedbump etc I hear a loud "PPPFFFFFTTTTT" coming from the passenger side front or rear tyre area - kind of like pneumatic air being released or something.

Never noticed it before the service or MOT.

Does this sound like a problem with the suspension to anyone?

Does the car have air suspension? If so check around the wheel arch in the area the noise is coming from for any air escaping sounds. I'd also check that the tyre valve isn't damaged. Happened to me on a previous service.
