Strange pulsing noise from rear of car in electric mode only

Hello can you be a little bit more specific, the issue is coolant pump or fuel pump? Both are located in the back. I have the same issue to my GLC 350e - 2018

Hi
I had that same thing, mine was the fuel pump in the tank, under the back seat behind the driver is an inspection hatch, take that off and the pump is underneath, unfortunately I couldn’t get a new pump anywhere except the main dealer, total cost was just over £1K plus vat.

Thank you fixed mine also, fuel pump fault. Though in Poland the cost of f pump 250 euro.. and replacement another 70. ( Cover by extended warranty anyway but nowhere near the amount you have paid..)
