So having replaced with NEW Borg Warner turbos, checked all pipes for splits, replaced with new inlet manifolds and intercooler the car ran fine for approx 500km then the code came back. Initially it would show up after about 45 mins of driving from cold but now it shows up almost instantly. So, when putting the diagnostics on, there is a difference in the reading between bank 1 and bank 2 EVEN BEFORE starting the engine...then you will see the readings are lower on bank 1 until the engine is blipped then the fault kicks in and the pressure drops significantly.
