    2017 Discovery Td6 HSE Lux Waitomo Grey

    3.0 L Tdi Underboost Fault

    P0299-77 code

    Anyone experienced this? Was making a right turn from stopped position onto busy street, had plenty of room to merge, that is until fault occurred, and truck went into reduced performance mode, suddenly I didn't have so much room to merge! Dealer checked turbo piping, monitored via pathfinder, cleared fault and reset engine adaptations. Test drove and declared good to go, root cause not determined. With 2500 miles on the clock this doesn't make me feel all warm and fuzzy Confused

    not yet! I have noted a slight sluggishness on a few occasions, but it may just be me being to relaxed with my throttle foot. Certainly no warning
