| P132B-00 (2F) Turbo/supercharger boost control A performance |
|
I have fitted a new perfectly working turbo and replaced all of the pipework, however I am still getting this fault code on start up and an engine fault message.
I have also checked wiring continuity between turbo and control unit plugs.
P132B-00 (2F) Turbo/supercharger boost control A performance.
The car drives normally apart from the fault code and message appearing.
Does anyone have any ideas what I can do to correct this ?

I forgot to mention, I had this code before changing the turbo which was leaking a lot of oil past the exhaust turbine, smoking and dripping oil from the rear of the exhaust.
As I mentioned earlier, the vehicle is running fine now without smoking or dripping oil. Engine performance is good.
Also the actuator is moving as it should.

Have you cleaned the MAP sensor after the repair? otherwise, there may be a small charge air leak, smoke test will help.
ETA
I can't remember if there is a teach-in procedure for the VVT, I've a feeling there is, maybe that is the issue?.

Yes cleaned map sensor.
Does anyone know if there is a vvt proceedure ?

I meant VGT. Variable geometry turbo. Or Variable vane.

Couldn't tell you - it's not something I use, it is niggling me that you have the same DTC after changing the VVT, did you check all the electrical continuity to the turbo and the pin grip at both ends?.
Even without end-to-end calibration, the old mapping should be somewhere close, close enough for the DTC to clear anyway. can you hear / see the actuator move?
ETA - just re-read your original post, which would preclude most of the above - can you smoke test the charge air side for leaks, it's also possible the turbo was built with the actuator arm in the wrong position, do you still have the old turbo to check against?
Another check would be to look at the actual values for atmospheric & boost pressure, these should be approximately equal with the engine not running (but ign. on) and obviously the boost signal should change accordingly (and smoothly) when driven, even slowly. At idle, you may see the boost pressure is lower than atmospheric, this is normal.

I dont have any smoke, but I removed the throttle flap housing from the manifold and put a rubber glove over the end, then I removed the boost pipe from the turbo and blew down it to inflate the glove. So I am sure that there are no leaks. Boost is good when I drive the vehicle.
The actuator arm is correctly positioned (same as the old one) and functioning normally.

The only other thing that comes to mind is the new turbo isn't able to move to the full extents due to either the rose joints or the gimballs in the turbo binding - also, is the actuator rod the same length as the old one?
I appreciate none of the above is easy to check....
Good bit of thinking with the 'inflate the glove' trick

All of the turbo fittings are within mm. of the original in position and movement.
I wonder what problem everyone else had with the P132b-00 (2f) fault code ?

Apart from stuck actuator faults !

Then that would leave either a faulty actuator or MAP - can you 'borrow' a MAP to test with?

Just another thought, when you say the boost is good, do you mean 'as expected' or 'surprisingly good'? If the latter then its probably going to be an under-reading sensor or an issue with the supply to it. You should have 5.0VDC ±0.25V and obviously a good ground, with the sensor disconnected you should see about the same voltage as the supply on the output wire, this will obviously drop when connected.
