So the issue is water in the fuel? And if so, why is this not corrected by the water separator/filter?
The issue is with excessive moisture deactivating the SCR system. What I have heard sounds like an issue post-DEF injection. http://www.dieselforum.org/about-clean-diesel/what-is-scr
I suspect something is going on where the DEF isn't being broken down to ammonia and the DI water is causing an issue.
Water in the fuel does not appear to be the cause. I was commenting on the poster that said that water had free entry into the diesel tank,. which is incorrect.
