Hi chaps, am struggling to find a clear description for fault code P132B. have searched archives, forums,google etc. reading the vague descriptions i have found but mainly relating to v6 pickup trucks in US, it looks like a boost pressure control related fault code. The symptoms of the car are it sounds a little diesel knocky (loud)only at low revs. has plenty of power if i accelerate hard once it's under hard boost 2nd 3rd gear at around 3750-4250 rpm it reduces all power, glow lamp flashes and goes into limp home mode. the fault may not happen for over half an hour of hard driving. I have checked to see that the electronic turbo actuator is moving freely. when i start the car the actuator arm moves forward as i rev the car it moves back and forth freely. my gut feeling is that possibly the car is over boosting due to the VGT vanes sticking and maybe P132B is an over boost fault code. but im only guessing. any help with code description much appreciated Cheers dave
