    VCDS Fault Code 009571 - Turbocharger Boost Control Position Sensor Circuit P2563

    Hi Everyone,

    First time posting here so would appreciate any help.

    I have a 2010 VW Scirocco 2.0 TDI

    About 2 months ago on our coldest day of the year, I needed to jump start the car. I used a portable battery pack (which I have used spontaneously in the past and always worked first time no problem) to start the car. However it took me 4/5 attempts to do this, the car was chugging until it eventually worked and the dash lights were flashing extremely quickly. Once the engine turned over, there were 2 warning lights left on: a flashing coil amber light and a solid non flashing amber engine management light. After driving for a bit these did not go away so I decided to take it to the local garage (not VW dealer).

    They ran a basic diagnostic test and it came back with 2 problems. The first being a glow plug that had gone out and the second one relating to the Turbocharger Boost Control Position Sensor Circuit (as the title of this thread suggests).

    It was hoped that this test might clear the lights - but it didn't. So it was suggested to get the glow plug replaced first. This was completely wedged into the engine and would only come out after having a lot of heat being applied to it. Once the new one was put in the coil light was still flashing. The Turbocharger code still remained.

    Now due to funds I have not been able to look into this any more until now. I realise I could be doing more damage to the car (which could be a greater expense) but I must add that I am seeing no change in performance to the driving of the car. It drives completely normally even now. The only thing worrying me is that the regeneration of the car cannot take place due to the engine lights being on - to clear the soot out (or this is what I was told by the garage anyway).

    So this week I had a vag- com / VCDS test ran on the car by the same garage (not a VW dealer). It came back with exactly the same error: VCDS Fault Code 009571 - Turbocharger Boost Control Position Sensor Circuit P2563 - Implausible Signal

    The garage is suggesting (from the Ross-Tech website) it is something to do the following:
    Wiring and/or Connections from/to Vane Position Sensor (G581) faulty
    Engine Control Module (ECM) faulty
    Vane Position Sensor (G581) faulty
    Binding Issues due to Adjustment/Turbocharger Excessive Carbon build-up
    Vacuum Leak from/to Turbocharger (Wastegate) Actuator and Solenoid Valve for Boost Pressure Control (N75)

    They cannot be more specific. They are simply saying to trial and error all these things until they find the problem. They are suggesting to clean out the Turbo first, replace the sensor second and then purchase some kit for the Vacum leak third. They also say it could be a faulty turbocharger or faulty actuator. To be honest I am not satisfied with all these many solutions which could cost a lot of money and they might not even be the problems. They have disregarded the fact these lights came on from jump starting the car - so my gut opinion says its something electrical rather than carbon build up for example.

    I've read a lot of on other web pages saying I could have damaged the ECU when jump starting. Could this jump starting also have taken out the glow plug (as there were no warning lights previous to this)? What do you likely think the problem could be? My gut says the ECU. Please see the full VCDS fault log below (hopefully you may be able to decipher the problem with the info):

    First posts normally go in introductions else you could get a free fix and we never see you again!!!

    VAG Error Code: 14846/7286/7934/009571
    EOBD II Error Code: P2563

    Fault Location:
    Turbocharger Boost Control Position Sensor (G581) Circuit - Implausible Signal

    Possible Cause:
    Malfunction Indicator Lamp (MIL)(K83) active.
    Power Loss
    This fault code may be caused when the Actual and Specified Turbocharger requests are considered Implausible by the engine controller.

    Fuse(s).
    Wiring/Connector(s).
    Turbocharger boost control position sensor (G581) faulty or Binding due to adjustment/Turbocharger issues.
    Excessive Carbon build-up.
    Vacuum leak to/from Turbocharger (wastegate) actuator and Solenoid Valve for Boost Pressure Control (N75).
    Engine Control Module (ECM).

    Possible Solutions:
    Check/Replace Fuse(s).
    Check/Replace all faulty Wiring/Connector(s).
    Ohm test Turbocharger Charge Pressure Actuator Position Sensor (G581), see factory repair manual.
    Check mechanical Turbocharger operation to rule out binging and excessive carbon.
    Check vacuum supply to/from Solenoid Valve for Boost Pressure Control (N75) and Turbocharger (wastegate) actuator.

    Special Notes:
    When this fault is found in the North American Region (NAR) Market 2.0L CR TDI:
    Measuring Block Group 034.2 (specified) and 034.3 (actual) Charge Pressure Actuator Position Sensor (G581) values can be logged to see if the fields should mirror each other or deviate to confirm a problem.
    North American Region (NAR) market vehicles that had Technical Product Information (TPI) 2025464 | Technical Service Bulletin (TSB) 21-11-01 or the latest Technical Product Information (TPI) 2025464/5 | Technical Service Bulletin (TSB) 21-13-01 completed to prevent no-start conditions in cold weather caused by a frozen intercooler may want to see this thread 009571 - Turbocharger Boost Control Position Sensor Circuit P2563.

    Hi Keith,

    Thanks for your help. Apologies I didn't realise it was meant to go there... not necessary looking for a free fix, happy to pay if it solves the problem! And of course if I do get some friendly advice then I will come back again

    So in your honest opinion, do you think this relates to the electrics directly linked with the turbocharger (as your fault codes software lists) or could it be the ECU that is damaged? As I mentioned, this fault came about after jump starting the car. The turbocharger seems to be working fine. I have seen no performance loss in the car at all.

    A shame I cannot give this report to some garages (or the reports I have already paid over 100 for). They will not accept them and insist they run their own reports first to charge an extra fee.

    Also would you suggest going to a garage that specialises in electronics or take it to VW and take the hit on price?

    Thanks again your help is most appreciated.

    Its hard to say what's causing the problem as we can't see the vehicle, do full system component checks with VAG-COM\VCDS.

    Would this have been done as part of the Vag-com test that I had done earlier this week? I have a whole report in front of me. Or is it a different type of test?

    With the suggestions in your fault codes list, surely if any electronics were damaged directly connected to the turbocharger (including fuses), then it wouldn't work and I would see performance loss? Or does it not work like that?

    I just want to rule out what it can't be first of all. My gut says to send the ECU away to be checked. But ideally it is something as simple as a fuse!

    Thanks again.
