Hi I know this is an old post but I tend to look through old posts for tips etc, so I have just had the exact same problem on my 2009 Opel Antara 2.0 CDTi, both codes P0299 and P0047 and distinct lack of power, everyone kept saying I had a split hose or vacuum pipe however I checked all of them and pulled all of the wiring apart checked the connectors all fine.

I was at the stage where I was really banging my head against a wall, anyway I had been on a test drive and I came back and turned off the ignition and there was a strange clicking/ whining noise and I found that this noise would go on for about a minute after turning the ignition off Everytime, so I started to remove everything to trace this noise, once I removed all the turbo pipework and heat shield I found that the noise was in fact the electronic actuator, I checked that the actuator was moving the boost rod and found that it wasnít, so I drowned it in WD40 and moved it back and forth by hand and sure enough the noise went away! I built the engine back up and finally my car is running as it should, it might have taken me 8 hours to find and fix the fault but Iím happy I have my workhorse back!!
