W220 320 CDI Power Loss

[nadeem]

Hi,

I have a major power loss no longer here the turbo boost. Scanned the car using Carsoft and reports P1403 Exhaust gas recirculation, HFM controlled Pressure transducer. Possible causes short circuit, open circuit ARF pressure converter and flaps to module or camshaft signal missing.
I think it could be a blown fuse or sensor faulty. I'm going to have the car scanned with Star for a more accurate reading.

What do you guys think?

Wasn't able to borrow Star so in the mean time checked fuses and vacuum leaks.

I'll swap the MAF from my other 320 cdi see if this makes helps.

Check and clean out your EGR valve - that had been many the cause of power problems

There's no air going into the ERG pressure transducer, which I believe open and closes the EGR. Further more as raise the engine speed I hear a vacuum leak right side of the engine. I'll root round the engine and pin point the leak.

No edit option for my last post.

Pipe from EGR to transducer was not connected reseated. However I can still hear air leak noise coming from the right bottom engine and still no boost.

Does anyone have a picture of the engine vacuum pipe works?
