A3 2008, coil light and limp

[Dan553399]

Hello,

A3, 2008, 2.0L TDI. Coil light keeps coming on and going into limp mode.

Getting the fault code 09572 - Turbocharger Boost Control Position Sensor Circuit
Signal too Low P2564 - Intermittent.
 

Replaced the boost control sensor and had it calibrated however the fault continues. Sometimes it’s fine for a week, other times it’s continuously happening. 

Taken it to a couple of places and no one seems to know what to suggest, at a bit of a loss really, any ideas?

Thanks in advance

Hi if the car has high milage it could be the variable vanes on the exhaust side of the Turbo are becoming stuck with soot or its even possible the Turbo is failing.
