Sound from gas tank
Hi, I have a 2023 model C300W4. When my car engine is turned on but the car is stationary, I can hear a weird popping sound coming out of the gas tank in the rear. I use Premium 93 gas from Costco. Would anyone have any tips here on what the problem is and solutions?

Did you ever find out what it was? I'm guessing the fuel pump. I heard that sound the other day sitting at a red light. I have a 2025 C300.

No, I did not. I still hear it every now and then.
