PEUGEOT 2017 Expert III (V) 2.0 BlueHDi 122hk P1497, P2562

Hi
I have a PEUGEOT 2017 Expert III (V) 2.0 BlueHDi 122hk
3 months ago the engine indicator light up and the car went in limp mode. I reset the fault codes and i could drive again. The fault repeated and now it comes every day when i start the car in the morning when its cold the fault code appears after 10.20 seconds. As soon its warm i can drive ant stop a whole day without problem.

The fault codes are: P1497, P2562 "Turbocharger. Actuator Too close in relation to the reference value"

I have checked the live data, se picture and my concern is that the "Position indicator of the turbocharger go to 0 "zero" when the fault appear. Normally it has the same valye as the "reference value". So i think it can be the turbo position sensor. But i cant fint out how it looks and where it is located on the engine. What is it and where? Someone have a diagram where all sensors, actuators and vacuum are located?

I have also a fault code U1F42 No communication with air Conditioning ECU, i dont know if that is related?

I hope anyone can help.
Thanks in advance.

Ok, sorry, but I don't have these codes for this specific engine as this is an Expert 4 van, not an expert III. I do know that when these 2 specific codes were present with engine DW10FD on a late C5, the technical bulletin referred to the replacement of the turbocharger vacuum pipe (if necessary), but this was supposed to be fixed with different material from build date 31st December 2016. Still, thought it worth a mention.

(18) Turbo Solenoid Valve
(19) EGR Gas Recirculation Solenoid Valve

Vacuum pipes are at (22, 23, 24 & 25)

(1) Turbo

Thank you very much for the answer and pictures.
But i wonder the fault code say "Actuator" for me that is a sensor that moves mecanically in/out. But a "solenoid" is in my opinion a something that is electric thing that control a movement, not read?
I can be totally wrong but its just my thought.

I tested yesterday and when the engine has been turned on and off 5 times, se result in picture.

"A". "Turbocharger Position Reference value"
When engine starts it goes directly to 85%

"B". "Position indicator of the turbocharger"
When engine starts 0% and after a while goes up to 85%

Sometimes when the engine is cold "B" is 0% until i have driven 50-500 meters, then the engine lamp light and the car goes in limp mode, both "A" and "B" goes to 0%.
When i drive until the engine is warmed up and do a reset i can stop for 4 hours without any fault codes when i start. Only when it has been standing over night.

Hope it make sense to you.
Best regards Ole

Hi

Unfortunately you don't have the last 2 digits of the fault code, there should be 6 - of which the last 2 digits further define the specific fault area. I don't have the codes for this late an engine - so I won't provide half a code as the symptoms and specifics can be irrelevant and this will waste your time. Example 'too open' or 'too closed' have different digits for the last 2 in the code. Further as I don't have the engine specifics, I can't advise as to what the normal settings should be. The differences in pressure don't look too out - but I can't comment on the time taken to reach the value as we know that the turbo only kicks at certain revs / loads when needed (variable geometry) - but as I don't have the data I can't help regarding the time to reach the values.

Ok, i will investigate further. Do you think that the (18) Turbo Solenoid Valve in yout picture is the same as faultcode P1497, P2562 "Turbocharger. Actuator"?

Best regards Ole

Hi Ole, no the actuator is the bit circled:

PSA don't provide these separately, but they can be bought online form aftermarket suppliers or the OEM supplier and often can be replaced without removal of the turbo - depends on vehicle and access of course.

Hi again
Today i got the item(18) Turbo Solenoid Valve (se picure).
On the new one there is 2 holes fore bolts. One at top and one at the bottom i cant even se the bottom bolt and dont know how to loosen if there is a bolt.
In the drawing is only one bolt?

Do you have any instruction how to remove the Turbo solenoid Valve?

Thanks in advance Ole

[OleT]

It dosnt looks like the drawing. But i took away the item(18) Turbo Solenoid Valve. Very tight, underneth was 3 hoses and 1 connector. Put in the new and cleared the faultcodes. Now it has been running for 2 days without any engine lamp on.

Keep my fingers x.ing.

Thanks for all help MArc

Hey OleT,

18 month has passed. Has the new turbo solenoid valve solved the code?
