Good morning all
I have been having Engine System Fault appear in the display after the 3rd time of starting the car the engine management light comes on and the following codes appear.

P138E Turbocharger boost control position sensor A -min/max stop performance

P132E Turbo / Supercharger boost control B performance

I have scoured the forum for an answer and there seems to be different remedy's to this.
I have no pipes with splits, the actuators are both free i check these every 6 months when i oil change
I have owned the car for 10 years its a MY08 TDV8 with 144000 miles.
my question is can it be fixed with a sensor or am i looking at new turbos, advice would be greatly received.

Thanks in advance,

Ade
