P2563 error code, flashing coil light, flashing EML (engine) light

[MHDxMK5BK]

This came on a few days ago, not used the car much since. I've searched around the other postings with this code in them and may well be the turbo actuator.

I'll keep you posted on how this unfolds and if anyone has anything else to check then please do let me know.

Data read with a ELM327 bluetooth plug (£6 from ebay) via ODB car doctor app on a Samsung Galaxy S5.

Did about a 50 mile run today there and back.

The EML stays on but when cruising steadily the coil light turns off but on braking for the next roundabout the dashboard dings and the coil light is flashing again.

This leads me to believe I've got a vacuum issue somewhere maybe. Best do some more research and checks as I'll be mighty cross if I get the turbo actuator changed just to find a vacuum pipe on the egr cooler is broken as was the case on this chaps car.

009571/P2563 - Turbocharger Boost Control Position Sensor Circuit
Possible Symptoms

MIL on

Possible Causes

G581 Faulty
Wiring and/or connections faulty
ECM faulty

Possible Solutions

Check fuses
Check wiring and connections
Ohm test G581, see factory repair manual


009571/P2563 - Turbocharger Boost Control Position Sensor Circuit: Implausible Signal

This fault code may be caused when the Actual and Specified Turbocharger requests are considered Implausible by the engine controller.
Possible Symptoms

MIL on

Possible Causes

Wiring and/or connections faulty
ECM faulty
G581 (Vane Position Sensor) Faulty or Binding due to adjustment/Turbocharger issues
Vacuum leak to/from Turbocharger (wastegate) actuator and Solenoid Valve for Boost Pressure Control (N75)

Possible Solutions

Check fuses
Check wiring and connections
Ohm test 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 NAR Market 2.0L CR TDI:

Measuring Block Group 034.2 (specified) and 034.3 (actual) G581 Vane Position Sensor values can be logged to see if the fields should mirror each other or deviate to confirm a problem.
NAR market vehicles that had TPI 2025464 | TSB 21-11-01 -or- the latest TPI 2025464/5 | TSB 21-13-01 completed to prevent no-start conditions in cold weather caused by a frozen intercooler may want to see this thread.

More than likely the diaphragm in the turbo actuator is leaking, a very common problem. Unfortunately there is no VAG repair kit for the BMR engine. Test the diaphragm by applying a vacuum to the actuator port and seeing if air can be drawn through.

Found a diagram.

Crasher: Tried to get the pipe off the Charge pressure control solenoid valve -N75- and gave up as was in danger of snapping something. I'll dig out a bit of pipe from the garage and have another go tomorrow. As the BMR has no repair kit what is required here and what's the ballpark costs?

[Crasher]

I take the pipe off the actuator (get a pointed hook under it to break its rubber grip) and then apply the vacuum, if air just pulls through you know what is wrong. When we get them in with this we send the turbo off for overhaul and the total tends to be around £900 all done including and oil and filter change but sometimes we do have to replace the oil feed pipe if it twists.

[MHDxMK5BK]

It's at times like this that I miss my Mondeo dearly! A diaphragm perforates and you have to replace a turbo! Outrageous!

Thanks though for the info, it's surprising you cannot just get the actuator separately, maybe I can find one somewhere...

Hi there crasher, I no this thread put I’m struggling with the same code. I have put a new turbo in my Passat 1.6tdi 2012 CAYC and the same code p256300 turbo boost control position sensor. I changed the actuator from the old turbo aswell and same code popped up with my coil light flashing and engine management light. I have also tried adaption with via vcds and still no luck. Any no the proper procedure as I am struggling with be nice if someone can help
Thank you

Hi,
Very new here,i have maybe the same problem,one day i was cruising with my Passat B6 2.0 tdi and i thought it isnt accelerating properly,i brought it in a autobahn put my foot on the gas pedal and the car wasnt accelerating as always and when i reached 90km/h the flashing coil light came on and i freaked out a bit ,did a research some said the reverse light maybe at fault but why isnt my car accelerating thats the whole isssue,i brought it to a mechanic he said the turbo has some faulty i dont know for sure what let me the car and i will make it accelerate again,is there any simpler issue and the mechanic is just wanting some money.

Thank you in advance

Start with a code read, it has definitely gone into limp home mode so there will be codes stored
