Shark Performance In Scotland
My old 06 plate 140TDI Stage 2 did this......if you gave it a bit of stick it would go into limp home mode. Turn off ignition and back on again and voila no problem. Turned out it needed a new turbo due to a faulty wastegate actuator rod. The wastegate wasn't opening at the specific time so the pressure built up until the engine management dumped it all. The fault was also matched with a siren noise from the turbo when driving. If you have this noise then get saving.
