Pressure Turbo Boost Gauge pick up point

I was wondering where is a good point to pick up for a Turbo Boost Gauge.

I would like to check my boost as I think the acceleration is a bit down on my 2009 1.6 HDi C3 and I cannot find any 0-60 or better 50-70mph stats anywhere that I could at least do a quantitative check of a sort.

Now I've been given a good gauge so I thought I might as well check the boost (instead of the OSB2 diagnostic that means me carrying around a laptop ect).

There was some information tips-for-a-diesel-powered-citroen-c3-f6 ... t2240.html regarding the vacuum but that is different to what I want I think?

Somewhere else on the net https://www.citroen-owners-club.co.uk/ci ... -pressure/

this test procedure is given:

DIESEL TURBO DV6TED4 FAP OR DIESEL TURBO DV6TED4 WITHOUT FAP OR DV6ATED4 TURBO DIESEL

1. Preparation
ESSENTIAL : Observe the following checking conditions : Engine at operating temperature. Vehicle in working order. Engine full load.
Connect the diagnostic equipment to the vehicle’s diagnostic socket : Measure the parameters.
2. Method of operation
Start the engine.
Engage the 1st gear ratio, and start the vehicle.
Engage the gears up to 3rd gear.
Decelerate to an engine speed of 1000 rpm.
Check the pressure (1500 rpm) : 0.6 ± 0.05 bar.
Accelerate hard : (change from 4th gear to 3rd gear).
Check the pressure (between 2500 and 3500 rpm) : 0.9 ± 0.05 bar.

Yes, that is not what you are looking for.


The official pick up point for turbo pressure is the turbo outlet hose. There is a citroen special tool for this test and its a replacement turbo outlet hose but with a little spigot for connecting the gauge.

thanks for pointing that out (literally ) maybe I'm best off with OSB2 for now unless I can find a suitable adaptor off webay

or taking it from the t-piece on the MAP sensor pipe if I've got one as suggested here https://www.406oc.co.uk/viewtopic.php?t=23034
