ok thanks for that will give mine a try tomorrow and report back. Do you have an engine bay cover on your car?The inverter module sits on top of the electric motor. The noise occurs when the cabin pre entry is turned on. It is on when parked and no one is in the vehicle,
I picked up my wife's new EQA on Sunday and when we used the pre-heat last night the sound is VERY loud. I'd describe it like an electric razor but very loud and enough for people to turn and see what the noise is. I had MB Technician around to investigate and he said this was doing what it is supposed to do! It uses the AC in reverse to quickly heat the cabin but for me this is not acceptable and in the early hours is very noticeable in the quiet area where we live.My EQC makes a horrible fan type noise from the inverter module area. Anyone else notice this. It’s head turning an I get comments from passers by.
I find it to be mildly noticeable and curious to others to have a car lightly buzzing however it is not horrible sounding to me anyway and I have had no complaints and noise blends into the background when familiar with it and I can often only hear it when close to bonnet and, crucially, not audible/disturbing inside nearby houses or my own even at 6am. I live in the suburbs however if it was the countryside I imagine it might be more audible inside a closeby poorly insulated house though in countryside houses are often further apart. Other brands are far more obnoxious and loud as are engines!My EQC makes a horrible fan type noise from the inverter module area. Anyone else notice this.

No There is no cover. Correction on the noise. Its coming from the Compressor at the bottom of the motor area. Its sounds like its coming from the module but close inspection reveals that it is just noise traveling up the casing. It is noisy but "normal" I still recon they could have made it to be quieter.ok thanks for that will give mine a try tomorrow and report back. Do you have an engine bay cover on your car?
How did you track that down? Mine opens the contactors once I pop the bonnet. I've always assumed that's an added safety precaution to make sure I can't bump into 400V even if I'm crazy enough to start hacking through orange cables under there. But no 400V -> no compressor, everything shuts down. And the app won't help - it disables remote access when the bonnet is open.Correction on the noise.

Interesting mine stays alive when the bonnet open. I used a mechanics Stethoscope. (You can just use a length of small plastic tube - one end in your ear and probe about the motor bay.) I also had the car on my hoist with the lower covers removed,How did you track that down? Mine opens the contactors once I pop the bonnet.
