Frequently Asked Questions
From £6,300–£6,900 including fitment, ECU reset, road test, and 12-month unlimited mileage warranty. Our pricing covers all labor, genuine parts including turbo actuator LR072310 and timing chain kit LR096682, and validation testing at our Billericay workshop.
The P300 engine is generally reliable but has known issues with the turbo actuator (LR072310) and timing chain tensioner (LR096682) in XE 300 SPORT models, particularly with frequent short journeys. With our rebuild process that includes upgraded components and ECU recalibration per JLR TSB XE-2021-03, we've restored over 185 Jaguar XE 300 SPORT engines since 2009 with excellent reliability for daily driving.
The most common failure in Jaguar XE 300 SPORT is turbo actuator failure (part LR072310), especially in urban-driven vehicles. This manifests as power loss and turbo lag. We see this frequently in X260 platform vehicles with less than 50,000 miles due to the stress of stop-start driving. Our solution includes the updated actuator plus ECU recalibration per JLR TSB XE-2021-03 to prevent recurrence.
Yes, the Jaguar XE 300 SPORT requires specific ECU coding after engine replacement. We use Autologic and JLR SDD tools to perform full immobilizer sync, adaptation of the engine management system, and integration with the vehicle's MHEV system. This is critical for proper operation of the P300 engine's performance profile and must be done according to JLR service bulletin XE-2021-03 at our Billericay workshop.
Yes, we specialize in P400 engine rebuilds for the Jaguar XE 300 SPORT. These high-performance 2.0L Ingenium AJ300 engines (394 HP) require special attention to the turbocharger assembly and high-pressure fuel system. Our rebuild process includes upgraded turbo components, fuel pump replacement, and ECU remapping specifically for the XE 300 SPORT performance profile. Rebuild cost ranges from £7,500–£8,200 with our 12-month unlimited mileage warranty.
The engine itself is identical across Jaguar XE trims (SE, HSE, R-Dynamic, 300 SPORT), but the 300 SPORT features a unique performance-oriented ECU mapping that delivers more responsive throttle and sportier transmission calibration. When rebuilding a 300 SPORT engine, we maintain this specific performance profile while addressing known weaknesses like turbo actuator LR072310 and timing chain kit LR096682 to ensure the driving experience matches Jaguar's specifications for this sport-focused trim.
