Last winter I had a problem where in extremely cold weather, when I left the car parked over night on a driveway with about a 25 to 30 degree slope with the back end lower than the front, the car, also a 1999 E300 Turbo Diesel, wouldn't start in the morning. At first it just wouldn't start no matter what I tried and I had to have it towed to the MB Dealer. They replaced the plastic fuel lines, filters, etc. and all was fine for a while. Apparently during the night, a leak in the lines allowed the fuel to drain back into the tank, virtually starving the engine.

Then in January 2006, another cold spell and the problem appeared again, but not as bad. At least I could eventually get it started. But this time if at some point I let the car parked on the incline, nose down, I found small spots of diesel fuel in the driveway.

I took it back to the MB dealer thinking something was wrong with their guaranteed plastic fuel line repairs. But this time they replaced the metal fuel lines, and everything has been fine since. No more leaks, but the cost of these repairs was out of site. For me it was worth it because I wouldn't want to attempt work like that, even though it may seem simple to some. But I didn't have the time or the inclination either. Plus there's something to be said about having work done professionally by qualified MB mechanics, if you can afford it.
