06 E320 CDI-Gas tank sloshing noise
I have had this car for a couple of months and there is a significant sloshing sound heard in the cabin from the diesel tank. When I come to a stop, there is a loud thumping sound in the cabin from the diesel fuel slamming forward in the tank...particularly when full. I took it to the dealer, they were unaware of that issue and how to correct it. They called Mercedes tech support. According to Mercedes, that sloshing is normal in the diesels. ..I was told the diesel has a different baffle system than a gas model. Anyone else have that issue with their CDI or any E Class for that matter? If it is in fact normal, I am surprised that it never has been mentioned as an annoyance. Thanks for your input...

In my 1999 E320, the sloshing sound was caused by water trapped in the rocker panel below the doors. The drains had plugged up and trapped the water. A piece of wire cleared out the drain and problem went away.
