Hi there,

Hoping someone can help with my car issue.

It's a 2009 VW Passat 1983cc tdi high line 140.

The fault I get is the yellow glow lamp light ( spring shape)
The codes I get from reader are
009571-turbocharger boost control position sensor circuit
000665-boost pressure regulation

I can reset the car back to normal by switching it on and off.

The fault only occurs when I'm driving at speeds of 70mph above and accelerating hard, the light will come on and the car will become slow to respond feels like turbo is not kicking in.
If I'm driving around town all day not really doing any speeds the fault doesn't seem to happen.
I've been told it could be the boost pressure sensor but then someone also said it could be a turbo needs replacing/recondishining?

All help is much appreciated thanks.
