    Strange noise coming from footwell / right side engine area when accelerating. Any ideas on what to check? 7g box 2015 changes gear smoothly.

    When does the gearbox need servicing?

    My car is Dec 2015. Only just started making the noise. Like a kid blowing a raspberry in the footwell.

    NOX sensor was replaced recently so wondering if something was not put back right.

    Not sure when to service gearbox, done 57k?

    Hi any one any ideas it’s driving me crazy. Think it could be related to changing NOX sensor.

    Not sure on noise, but if it happened after NOX sensor fitted I would be checking it in properly.

    Gearbox is 38k miles on the newer ones I believe.

    Hi, merc want diagnostic fee for looking at it, said it can’t be anything to do with NOX sensor being replaced.

    On the gearbox apparently it’s life / 100k which seems a lot before a service. 2015 merc estate mag premium plus c220 7 speed.
