V60 D3 Turbo problem

while i was making some measurements today i noticed that the pressure sensor from the catalytic converter is making a high pitched squealing sound with the engine off.
However it has not flagged up on the obd/p codes. could this sensor be causing a boost issue?

from your first sentence it seems you have a boost leak from a hose or intercooler .

Hi, Sorry for necroposting, but this is EXACTLY the same issue my 2010 D3 XC60 is having. Have you ever resolved this? You have any suggestions of what I could try?
I'm also getting the following fault codes:

• P004900 (Turbo Turbine Overspeed)

• P023600 (Boost Sensor A Circuit, circuit range / performance)

• P029900 (Turbo Underboost)

• P046C85 EGR Sensor A, Signal above allowable range)

Any help, pointers or information would be greatly appreciated.
Thanks.

Definitely replace the TMAP sensor on the pipe going into the intercooler on the lower right hand side as you are looking into the engine bay.

Also check the MAP sensor isn't blocked on top of the engine.

There I'd also a PCM upgrade available from Volvo to cure P0299 being logged under long periods of full throttle, but as you have other codes this is unlikely to be the cause.

Thank you very much for your reply.
What's the best way to get part numbers for Volvo parts?

I can move the EGR valve linkage by hand, so I assume it is not stuck, and all the piping including the throttle body was clean.
I can also move the turbo wastegate actuator linkage by hand, so I also assume that isn't stuck, but would there be any point in taking the piping off and giving it a clean / look-see?

Turbo tubes have been checked and valve was changed, but it didn't help. My third quess after tubes and valve was sensor malfunction, but it is measuring...although wrong percentages...unfortunately sensor is integrated to turbo.

I found one similar case in Germany and turbo change solved it...which is not my first option.

Local volvo dealer is not much help.

Any similar cases? I'd appreciate!

Was the issue found? Having the same issue now, after my Turbo got a new core and nozzle ring.

Did you sort this. I’m having the exact same issue on my V70 D3. I’ve unclogged and cleaned the sensor on the inlet mani which was really chocked up. Improved for a little while but still the same now. Got bad mpg aswell as the hissy sound low down the revs until you floor it then it clears and goes. I’ve removed the pipe under the intake mani and scooped all the soot out no different. No splits in boost pipes. Removed the sensor on intercooler which was surprisingly clean. Cleaned it but still the same

Yeah got mine sorted, the turbo actuator was not giving correct readings. Replaced the whole turbo, and it's only smiles again.
You do get aftermarket actuators, but I was told they do not last as long as the original, and the original you can't get seperate.
