009571 - Turbocharger Boost Control Position Sensor Circuit P2563

[lcf666]

Hello guys,

I been having this code for some weeks. I have a Passat 2010 B6 with 2.0 140 CR CBA Engine. So basically the coil light starts flashing and the car seems slower, not by much but I think I can feel it. It happend several times randomly, always the engine was warm and at low rpms.

This is what I found:

So, the Implausible Signal is the -2.4% value on the Lambda

Here I have the full Auto Scan

And here I did a log of the Measuring Block 34 and 32 under WOT in 2nd and 3rd gear.

Now, after reading several threads it looks like the most probably cause is the diaphragm in the turbo actuator is leaking (also called "vacuum unit for turbocharger")

In the workshop manual for CBA engines:

Pressure canister
 With position sender for charge pressure positioner - G581-

So I have some questions:

1. What do you guys think?
2. How far off I'm of the actual issue
3. Anyone has experience changing this?
4. Is it hard to calibrate once replaced?



Thanks for the help!

Yes you need a new actuator, suck it and see......

Crasher, I read so many related threads that I was wishing you reply! so.. should I buy a professional vaccum pump.. or the those from the ad on the sidebar

Thanks!

I have a Mitty Vac but I use a piece of 3.2mm vac pipe and the Mk1 mouth....

Hi Everyone quick update.

I bought a vacuum tool for 15€ and tested the vacuum, there was a leak:

Then I bought the wastegate in a VW dealership 195€ and you will need a tool similar to this one: Runtime Error cost me 6€. 2 hours to change it.

Thanks Crasher!
