Fitted across the X761 generation from launch in 2016 to the present day, the AJ300P is part of Jaguar's modern Ingenium engine family and shares its fundamental architecture with the diesel variants in the range.

How much does a Jaguar F-Pace P400 engine rebuild cost? Rebuilds start from £3,600. Exact price depends on condition and parts required — submit your reg for a fixed-price quote. Which engine code is fitted to my F-Pace P400? Enter your registration on this page and we'll confirm whether you have the AJ300P — the only engine used in this variant — along with your exact spec. Do you rebuild AJ300P F-Pace P400 engines? Yes. We replace timing chains, bearings and gaskets as standard on every AJ300P rebuild. Do you supply used F-Pace P400 engines? Yes, in some cases a matched low-mileage used engine is the right option. Our team will advise honestly once we've matched your registration and understood your situation. Can you recover my F-Pace P400 if the engine has failed? Yes — nationwide recovery is available from £70, and most vehicles are collected within a few hours of booking. How long does an F-Pace P400 engine rebuild take? Most rebuilds are completed within 3-5 working days from the time your car arrives at our workshop. Is rebuilding better than fitting a used engine?
