P0087 & P2047 OBD II Codes after CEL and loss of power on 07 E320 Bluetec

Just 3 days ago, my car threw a CEL while driving. Power seemed reduced, but I was in low speed traffic and just wanted to get home so I didn't test it. Started it up and drove it a few times, and it drove fine and the CEL light went away. Today I was driving about 50MPH when the light came on again. This time, because I was merging onto a highway, I felt an immediate impact on performance. The car almost didn't want to Rev higher than 2K, even with flooring it. I could manually downshift and get it above 2K, but didn't want to force it. I could still accelerate to 65, although very slowly (almost like it was now naturally aspirated, but with even less power compared to a 96E300D which I have and is NA).

Scanned it with Torque and a bluetooth OBDII scanner, and it came up with the following codes:

http://www.obd-codes.com/p2047

Some quick googling looks like it could be related to a fuel pump issue, but I haven't heard of too many of those with these engines.. Looking for some guidance.

P0087 & P2047 OBD II Codes after CEL and loss of power on 07 E320 Bluetec

I'm making the grand assumption: Turbine inlet guide vane solenoid / motor failure, for whatever reason, vane position sensor, solenoid/motor, etc.... I had an identical set of symptoms with my MY2009, complete loss of boost pressure. I don't have access to my service records right now, but as soon as I can I'll send what I've got. Mine was a warranty issue at around 50K miles. Now passing 101K, still extremely impressed, what a great car!

You should read codes with a proper tool (Star Diagnosis). Which control unit was supposed to give P0087?

P2047 is for "Rail pressure monitoring via volume control valve- The rail pressure is too low".

The inlet port shutoff motor (M55) could put the engine to limp-home-mode if oil has leaked from the turbo like in the attached photo. M55 fault codes is 2530.
