My 98 E300 TD was running on a high percentage mixture of bio diesel until the cold whether froze the fuel in the lines. After a few days of trying to get it started the temperature rose enough to unfreeze the lines.
Since then I've run it on 100% pump diesel and it's been fine other than a rattling noise between 1000 & 1200 rpm when cold. Once hot the rattle more or less disappears or certainly becomes less noticeable. I've tried a couple of bottles of injector cleaner but it's not resolved it.
I can't remember how noisy the car was when cold before this problem.
Any ideas?
