EGR differences ?
 

What does Mercedes-Benz do differently with their EGR systems? It seems a common issue with VW and even larger American diesel engines. I seldom read about EGR valve or EGR cooler issues with Mercedes-Benz. Do they take a "better" or different approach? Just courious.

They stick (open closed half way sometimes). Most people opt to not employ their use therefore eliminating the need to wonder about such issues.

I threw mine away two years ago, its working very well!:D

They get stuck open once in awhile.

Better in the way that a simple BB in the vacuum line can render it useless unless it is stuck open.
