Hi Guys, I´m about to bite the bullit and replace the turbo on my wife 2007 2.0 DID. It has had the dreaded intermittent engine overboots condition (fault code PO234) for past 6 months. I have dealt with this on other Turbo diesel vehicles with VVT, and in the past have been successful in resolving it by either replacing or cleaning the turbo. In this case its so much work to access the turbo I would prefer to replace, however here is the quirk that adds a small doubt in my mind. That quirk is she just asked me to look at a strange sound from the engine bay, that she noticed after a long drive. I quickly found what had caused this, it was the throttle body that had failed and made an obvious noise/vibration (the electric servo has lost death off the drive cogs and it no longer moves). I disassembled it to confirm this and ordered a new one. I then put it back together and reassembled it on the car, it still doesn't work but the car seams to drive fine? She didn't notice anything unusual at all on the drive, she did have over boost and limp mode a couple of times but that has ben the norm now for a while and when I have controlled this it has given me the P0234 code which I had presumed was the turbo. As far as I am aware I can't see how the throttle body would cause this fault code, I would have thought it would rather raise a fault linked to the TPS? My gut feeling is this is a red herring and is just another problem and my core problem is the turbo. Does anyone have any opinions on this or believe otherwise given my recent findings? Thanks for your help, regards Jim
