Re: C5 2008 (X7 ?) Turbo Fault
I think i maybe able to take the car somewhere tomorrow,fingers crossed, that has a vacuum gauge that maybe able to test the vacuum pipes, but i have no idea of what the values should be lol
Any help greatly appreciated no mad rush, not going to take car in till tomorrow afternoon

Re: C5 2008 (X7 ?) Turbo Fault
I can't copy the diagrams/pics but here's the text of the test.
Check : Air supply circuit
B1HD2HP0 Check : Air supply circuit
ESSENTIAL : Observe the safety and cleanliness recommendations.
2. Check
2.1. vacuum pump
Connect the tool [ 1] to the vacuum pump (1).
Start the engine.
Wait 30 seconds.
The vacuum value should be 0,9 ± 0,1 bar at idle speed.
N.B. : The exhaust gas recycling valve is not linked to the air supply circuit . The exhaust gas recycling electrovalve is controlled by the engine ECU.
2.2. Turbocharger wastegate valve
Connect the tool [ 1] to the valve (2) (pipe with grey mark).
Apply a vacuum of approximately 0,8 bar The shaft "a" should move by 12 ± 2 mm.
And for driving test of turbo...
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.

Re: C5 2008 (X7 ?) Turbo Fault
I believe there is also a boost control valve which turns the electrical signal into a vacuum signal, and they can get sticky, or the filter in the atmosphere port of that valve can get blocked. A lack of vacuum could also cause a loss of boost.

Re: C5 2008 (X7 ?) Turbo Fault
That's the electrovalve I said was at the back of the engine, Colin. I think others have said it's easier to access from under the car than above.
A video on what it looks like and how to service it (albeit on a non-PSA vehicle I think). Mark which hose goes to which port as you don't want them transposed on refitting.

Re: C5 2008 (X7 ?) Turbo Fault
Quick update
Did not manage to get to the garage this afternoon, car has finally thrown its toys out of the pram and is now parked in the drive with a gallon of petrol and a match for company
It is like riding a bucking bronco, 1 min it will rev to past 3.5k in 1/2/3 but then just goes flat, then it revs then it doesn't, pulling away at a roundabout was slipping the clutch hope it revved and the gap was big enough to get a fleet of double deckers out.
Off to look at a cheap runaround tonight so i can get to work and back whilst i contemplate whether or not to strike the match

Re: C5 2008 (X7 ?) Turbo Fault
Sorry - I've had PC problems (fried GPU) , so been on and off the Forum whilst I've secured another one and all the potching about - so missed this post Mike.MikeT wrote: ↑11 Nov 2018, 16:41 Perhaps Marc would be kind enough to provide VIN-specific information from Citroen; Fault code descriptions and testing procedures for instance?
Timely servicing is important due to fine tolerances of modern engines. For instance, what effect do you think a blocked air, fuel or oil filter might have on turbo boost?
If the match hasn't been lit yet, I will see what I have. This being the DV6TED4 110 with DPF.

Re: C5 2008 (X7 ?) Turbo Fault
i'll pray for you after going( on going still ) on a magical mystery hunt....save a match for me
i WILL find time to take another look at mine, 5 cars on the drive is 1 too many although we all know that the perfect number for anything is n + 1 right?

Re: C5 2008 (X7 ?) Turbo Fault
Just a thought, disconnect the doser pipe, you wan't have filtered intake....but, better than the match option. It will run as flat as.. but it will be smooth and will cuise at 60, it will chuck loads of faults on diag, and it will smoke black when booted, then work backwards

Notice the BX is still top the list but sadly gone

Re: C5 2008 (X7 ?) Turbo Fault
Blimey Colin, that's terrible.
PM sent.
No worries Marc. IME, power cuts and brown outs too frequently co-incide with damaged electronics

Re: C5 2008 (X7 ?) Turbo Fault
Can you check the injector clamps? Is there any movement, even the tiniest in the injector(s), along with carbon build up at the base? Did it ever go for the recall for the turbo oil supply pipe? The recall was to remove 1 of the 2 gauzes.

Re: C5 2008 (X7 ?) Turbo Fault
Ok so here is what I have for the P0299 Error:
As far as testing goes, you'll need some testing tools, the live data and a diagnostic additional cable as follows:
Tools:
Check
N.B. :If there is a significant difference in the pressure read on the diagnostic tool and on the pressure gauge, replace the turbocharging pressure sensor.
If the pressure taken in the circuit is lower than the value given, check the following components:
Fault code | P0299 |
After sales description of the fault code | Turbocharger pressure signal: Pressure too low in relation to the reference value |
Description of the diagnostics | Difference negative for 5 seconds, between the turbo pressure reference and the measured turbo pressure: The pressure measured is lower than the reference, around 300 mbars for an engine speed above 2500 rpm |
Conditions of activation of the diagnostics | Consult the associated contexts for the Pcode forwarding conditions In particle filter regeneration with engine speed above 1800 rpm Not in particle filter regeneration with engine speed under 1500 rpm |
Conditions of disappearance of the fault | Driving for 5 min with several full load accelerations for 10 seconds |
Down-grade modes if fault present | Use of the flow calculated Cutting of the EGR butterfly (turbo air cooler), EGR valve and bypass butterfly (inlet air heater) in all operating modes Cutting of cruise control Change to "easy move" torque invalid (Deactivation of automatic mode for the electronic parking brake) |
Switching on of the warning lamp and/or warning message | - |
Main customer complaints likely | Lack of power Noise Smoke from the exhaust |
Suspect areas | Air meter restricted Clogged air filter Obstacle obstructing the air passage Air lock between compressor and engine Turbocharging pressure sensor Turbocharger position copy sensor Vacuum problem Variable geometry of the turbocharger jammed in the "minimum turbo" position Faulty turbocharger |
Tools:
[1]pressure gauge for checking the turbocharging pressure (-).1604.A. | [2] Tool for checking inlet air pressure-vacuum (-).0171.G2. |
Disconnect the connector (at "a") (if necessary). Remove:
| Connect:
|
Engine speed (rpm) | Turbocharger pressure ( bar) |
2500 | 0,2 ± 0,1 |
4000 | 0,7 ± 0,1 |
If the pressure taken in the circuit is lower than the value given, check the following components:
- The turbocharger air inlet and outlet ducts
- The turbocharging air cooler inlet and outlet air ducts
- The turbocharging air cooler
- The turbocharger

Re: C5 2008 (X7 ?) Turbo Fault
Sorry for the late reply, had to go to work today
The injectors have been checked, no movement and no carbon build up at the base. As for the recall i really have no idea, we bought the car in 2011 from a main stealer ( could use other words but...) and have no paperwork to suggest yes or no.

They will have the record of it being done. You can call any dealer with he VIN and they can check for you.
