Turbocharger Implausible signal P2563

[968p58]

I keep getting this P2563 error on my 1.6 tdi Leon 2012.


Have tested the turbo actuator and it holds vacuum and checked voltage at max vacuum which is at 3.5v. minimum is at 0.7v so nothing looks to be off there. Currently confused as to what could be causing it... is it a faulty turbo?
Someone suggested regenerating the dpf but by the looks of things it doesn't need to be regenerated??


Any suggestions welcome.

10hpa on the diesel particulate filter at idle means that the filter is contaminated, try to burn it out.

Thanks for the reply. Do you recommend a manual regen using vcds? I'm waiting on some dpf cleaning solution to get delivered in the meantime. Not too sure how the dpf would cause this error though even though that one garage was very sure it is that by just hooking up an obd machine and reading the p2563 code.

Took the car to another garage they said it could just be the turbo that needs replacing based on the information I gave them.

Yes, I use vcds for forced regeneration

Soot mass is OK 6 mg.It dont need regeneration.You need to check vacuum circuit,its very common issues.Check cold egr actuator first.

This P2563 code is related to the wrong position of the turbocharger geometry monitored by the sensor
The reasons may be and needs to be checked
1 Baked turbine, vacuum lines, check valves, "pear tightness" and the error will still appear, it is necessary to check the operation of the Vacum pump.
2 The pressure that the pump generates at low and high speeds is important
3 There is a flap in the air filter connected to the vacuum and the sensor and it jammed causing such an error
This error with the DPF has little to do with the wrong direction of repair

Great lots of different information!

disable the turbo, go for a drive see what new exciting fault code you get.

can you get a vacuum gauge on the pipe and give it a bootfull
