I'm experiencing the infamous diesel leak that has plagued my car for the past 8 months. Last time they clamped three small leaks. It seems as though it is back again. The garage smells horrible and I'm truly concerned about the future of my CDI. I absolutely love the car but I don't know if I can "invest" anymore time with car and my SA. I've called the SA and will let you know what transpires in the next few days.

BTW, this is the fourth time I've taken it in for the same recurring issue.

Without seeing the car its tough, but I've had a few 320 CDI's come in leaking fuel. They always are leaking from the rubber hose coming off of the fuel filter, not at the connection at the fuel filter but on the metal line on the other side. I have tried to reseal that connection with no success. I replaced the hose and check for leaks, and never have had one leak then. The only problem is that hose is a special order part from germany, so it can take up to 3 weeks to get the hose, but it is cheap if it is something you would have to pay for. Dont worry about the car though, you have a great car and this is such a small problem. Diesel fuel is safe anyway, you dont have the fire hazard you could have if it was a gasoline engine. Good luck.

Thanks! It's reassuring that it may not be such a big deal after all. I absolutley can not think of another MB or car that I want to to drive.

I feel your pain, I have had simliar problems with my CDI, I love the car, but I would be scared to see what it would cost after the Warranty period is up. I now take my CDI to an indy, who does exceptional work and is able to work with me and fix all the fuel leaks. He even offers a 1 year warranty on his work. I trust him more than the MB TECHs, as I know he does quality work and won't jerk me around. I posted a thread on here earlier about what I went through when I took my car in for a fuel leak. Good Luck.

I had the replacement hose done as MBTech explained and have not had any issues since.

MBTech2003, You hit it right on the head. I took my 2005 CDI to the dealer twice last week. First time they said they found a loose hose clamp at the fuel filter. (I see that there is now a non-crimped clamp there.) Then when I got it home, I smelled diesel, so I popped the hood and saw a diesel drop hit the belly pan. So I took it back. They cleaned it and said they couldn't find a leak. I gave them the benefit of doubt that what I saw was from the previous leak. Well, I got it home again and saw a drop at about 1 drop every 2 seconds, and traced it back to where you said. Bravo!! Now I hope you are wrong about having to get the hose out of Germany. I took a picture, but can't figure out how to attach. The "insert image" prompts a URL rather than letting me browse my hard drive.
