For what it's worth, this thread: http://sprinter-source.com/forum/showthread.php?t=17039&highlight=2047
had Jon Caples saying that a P2047 (for a 2007-2009, at least) is:
2047 - Fuel rail pressure volume control maximum pressure has been exceeded

..so i read that as "too high", not "too low".
Could a different injector be allowing cylinder pressure to leak back into the fuel line?

What device provided the P2047 code? Generic OBD scanners frequently show incorrect (thus misleading) codes in NCV3's

jinxx,
How many miles on your 2010 Sprinter?
If under 100k why not take it to an authorized Mercedes Benz Commercial Sprinter dealer and have it diagnosed on the MB SDS system.
It will probably tell you the code and sub code that will lead you directly to the sensor/device that's causing your issues.
Up to 100k, it very well may be covered under your emissions warranty.
