I had similar problem with a Focus 2.0 Tdci, same DTC p0642, reference Voltage sensor A. And de problem was a shortcircuit in turbo sensor.

Then i think you have one sensor in shortcircuit. Connect diagnostic tool and unplug sensor one for one, and after unplug a sensor try to erase DTC codes, when you can erase P0642 you know then what sensor is in shortcircuit.

Notice that the VAG's PD AND CR TDI engines have rev limiter, when you are standing on full throttle engine shouldn't go more than 3500 rpm PD and 2500 rpm if it's CR! wink
