Little update…. Today the boost pressure sensor was replaced, the turbo and actuater was checked and working fine…. The voltage to the sensor was checked and he said he couldn’t read any voltage conning to the plug? He’s all out of suggestions does anymore have any idea what could be causing this, or even better anyone in Oxford that’s willing to help. I’m off to snowdonia next month and have mot after Xmas so desperately need this sorting asap
