I have a 2004 SL350. There is a loud banging/knocking sound from behind the drivers side seat which I first thought was something in the boot or roof mechanism but now I think its to do with the fuel tank as the regularity and intensity varies depending on how full the tank is.

Does anyone have any experience of this and if so how and how much was it to fix?

Thanks in advance
Luis

There was a baffle problem on 230s but I don't know what year it was fixed. A new tank is around £600 + fitting

It affects cars 12-02 onwards, again in the USA most got it done free.

I am sure that we are paying for all the USA freebies ..

Thanks for your responses. What is baffle then? The fuel tank moving around or something

Inside the fuel tank is a plate (the baffle) that helps stop the fuel sloshing about..

Some argue over this, but a friend in Watford used a pair of long blacksmiths plies and wound it up and pulled it out through the hole in the top
