Variable resistance turbocharger

Post by Lynnzer »

I've been aware of what I thought was a case of excessive turbo lag for a couple of months and yesterday I had an opportunity for my nephew to give the system a once-over to check for error codes.
I got a P2566 code with the message being Variable resistance turbocharger. My contact at the dealer who sold me the car says it should be included in the warranty and advised me to contact the nearest Citroen dealer to arrange repair. The dealer who sold me the car is at the other end of the country so I must do it locally.

I called the nearest at Sunderland and they told me that they would have to run a test (ie, duplicate the testing already done but at a cost of God knows how much - but probably £100 or near).
That would be necessary as they say they will run extra tests. I don't see what "extra tests" they can run.

The cost of that would be covered by an agreed warranty issue but if it's an electrical problem that won't be covered.

I hate the prevarication of dealers in such situations, however is it likely that the error code and message is the result of an electrical problem?
If it is, then it would probably be better if I let my nephew do the repair at his own garage instead.

It’s fairly standard for a dealer to say this to you, as they need to make you aware that someone needs to cover the investigation costs if it turns out to be an issue thats not covered by warranty.
Of course they need to do there own investigation, theres no way i would take someone else’s word for it & i cant imagine any dealer in their right mind would either.
As for extra testing, for warranty on certain components they need to follow a guided diagnosis tree to have proof for warranty, Citroen can log in & see if this had been done or not & if it was done correctly.

Also, bear in mind that if you have any work done elsewhere by a non-authorised repairer / DIY, they could decline any warranty work if they think there are grounds / issues that a fault could of been caused or made worse by a third party - so think about it if you are considering undertaking your own actions where you have a dealer warranty.

Is this for your DS5 or another car? If you pop the VIN up I may be able to check the fault code as it relates to your vehicle.

Fault Code:P2566
Description of Fault: Variable geometry turbocharger: Excessive drift on the last initialisations of the upper stop:
The fault is activated just after the initialisation of the upper stop.

Possibility 1
Drift less than -0,5 V or greater than 0,5 V in the initialisation of the variable geometry turbocharger upper limit relative to the first initialisation

Possibility 2
Drift less than -0,3 V or greater than 0,3 V in the initialisation of the variable geometry turbocharger upper limit, relative to the last initialisation the previous time the network (powerlatch) went to sleep

The fault immediately appears
Conditions for Fault to clear: 3 successive starts, allowing time for the network to go to sleep
Downgrade Modes whilst Fault is active:None
Symptoms:
  • Lack of power
  • No effects immediately perceptible to the customer
Suspect Areas:
  • Turbocharger (The variable geometry of the turbocharger is locked)
  • Turbocharger electrovalve
  • Position indicator of the turbocharger
  • Vacuum circuit
  • Electrical harness
