The 16v Hdi with the vacuum controlled variable vane turbo was down on power in the low rev range. It affected pulling away and very noticeable trying to go up a hill in 3rd, changing down to 2nd would help keep the RPM high an more power is delivered.
Removing the air filter box and air pipes gives access to the air reservoir and the turbo and EGR elecrovalves witth their associated vacuum pipes.
The flexible termination pieces (marked in red on the diagram) were found to be split in some places and the splits causes a vacuum leak. With vacuum leaking, there isn't enough vacuum to drive the turbo actuator fully.
The split pipes that caused the power loss problem:
There were no Citroen parts available at the time and some 4mm ID silicone vacuum hose was cut and used to replace the split pipes.
16v 1.4 HDi lacks bottom end power
