Help I'm on my bump stops! HDC Fault

Whilst taking the dogs for a walk this afternoon I got the dreaded BONG! HDC Fault special programs unavailable BONG! suspension lowered. I drove very slowly about 1 mile back home and switched the engine off and back on again. The disco started the suspension raised quickly and the pump stopped running. I drove off again and within 10 minutes of driving BONG HDC Fault special programs unavailable suspension lowered. Turned it off and on again everything back to normal. This time I went straight to local indy who I use and got him to read the fault codes using Auto logic. The following fault codes were stored.

p132B-22 Turbo Boost Control - Signal amplitude >Maximum
P023D-21 Manifold Pressure sensor correlation - Signal amplitude
P2199-21 Intake Air Temp 1/2 Correlation - Signal amplitude
P132b-21 Turbo Boost Control - Signal amplitude

Other codes were stored but he said they would be because the engine faults had disrupted the signals and caused the other control modules to have a fit.

Hopefully someone will be able to help me with this please.

Thanks

Brake bulbs/switch on brake pedal can cause similar and cheap to check.

Hi thanks for that. I have recently replaced the brake pedal switch and have also upgraded the rear lights to disco 4 LEDs do theses suffer with the same issue?

clear the codes and see what is the first one to come back.

maybe it needs a new MAP sensor

Just to come back to this the cure was to have my wheel sensors "zero'ed" after having a "proper" (don't go near kwik fit or Bushes neither know a thing about discovery's!) four wheel alignment. The sensors where saying my drivers side front wheel was 90 degrees out so the Disco though she was crabbing so through a series of faults.

I hope this helps someone!
