2005 E320 CDI cold start problem
 

Hay guys, it seems sometimes that when it rains it pours, lol!

In the last couple of days, my E320 CDI is experiencing as I can best describe it as a hunt during cold starts. The engine has a rhythmic hunt or, better stated a surge upon cold starts the lasts about 10 minutes and then it runs normal! The fuel filter was replaced about 2 years ago and I've only put 12,000 miles on the car since!

I just don't have the vocabulary to descibe it better, when I was a mechanic some 20 years ago we would describe this problem as a hunt, like hunting for an idle.

my past thread about my turbo making a whistling sound was exactly that, an air leak. Thank you

Any codes? That's where I would start.

Any strange odors from the tail pipe when you cold start it ?

There's a pretty good thread on 05-06 E320. It mentions injector seals can commonly go. You may want to check those as well.
