Hi!

I'm experiencing a significant loss of power in my Volvo (error code: deviation in turbocharger pressure control). According to the diagnostic tool, no boost pressure is being generated.

The intercooler was covered in oil, but I couldn't detect any leaks.

The turbo's wastegate adjustment is easy to operate, and the exhaust values are quite good, so there's no soot.

I still need to check the vacuum adjustment.

Could a faulty intercooler be the reason why no boost pressure is being generated or can be generated?

Well, that would be easy to verify... but from my understanding, it's nothing unusual for the D5 series.

...

Kann der Ladeluftkühler schuld sein das kein Ladedruck aufgebaut wird bzw. werden kann?

Yes, taking shortcuts makes you smarter icon_wink.gif.

It was due to the vacuum system, which lost pressure through the front engine mount. icon_wink.gif This is controlled by vacuum in the Volvo.

That's correct, yes. Great - I'm glad it was simple.

Thank you for the feedback! Nevertheless, the turbocharger system should be checked for leaks, because if it is sealed properly, no oil mist will leak out. icon_idea.gif
