GDE, I just saw one of your other posts (number18 on "3.0 CRD electronic throttle control error", and there you say:
"P0046 is most likely causing the low boost code P0299. P0046 signals something internally wrong with the 'rotatry electric actuator' that controls the vane position on the turbocharger. The is the black box mounted on the turbo. It may be the internal circuit has overheated and is not moving correctly or keeping the vanes in the proper position based on speed/load.
Clearing the codes to see what comes back is generally good practice, most of the other codes seem like random errors and would not cause the low power issue. After clearing, does the Jeep perform well again? See if it works well with a cold engine and then with hot engine. If problem re-occurs then the turbo will need maintenance. Unfortunately, if that is the case the turbo is sold as an assembly (cannot replace just the REA)."
But in this post you said that:
"If you can take pictures of the part numbers on the REA unit, I will investigate sourcing it. No sense changing the entire turbo assembly for a relatively cheap part"
I'm confused now whether the REA can be replaced separately from the turbo or not?
Thanks in advance for any clarification you can offer.
