Frequently Asked Questions
From £6,200–£6,800 including fitment, ECU reset, road test, and 12-month unlimited mileage warranty. Our price includes the reinforced valley pan gasket LR012345 and updated timing chain kit LR096682 specifically for the X202 generation.
Very reliable - we've rebuilt 75+ X202 D200 engines since 2017. Our rebuilds include the updated timing chain tensioner kit LR096682 and remanufactured EGR cooler, addressing the two most common failure points in the X202 generation. With proper maintenance, our rebuilt D200 engines typically exceed 100,000 miles.
Valley pan gasket failure is the most common issue in X202 V8 engines, typically occurring between 60,000-80,000 miles. Unlike later models, the X202 uses an aluminum valley pan design that's prone to warping. We replace it with a reinforced gasket LR012345 and perform complete sealant refresh at our Billericay workshop to prevent recurrence.
Absolutely - the X202 generation has a known timing chain tensioner design flaw. We replace it with the updated kit LR096682 and perform precision alignment to ensure proper tension. Our metrology process measures chain stretch to <0.05mm tolerance, and we include this critical service in all our X202 engine rebuilds at our Unit A5 Windsor Road facility.
Yes - we use Autologic and JLR SDD tools for full ECU coding and adaptation specific to the X202 generation. This includes recalibration per JLR service bulletin SWE-18-03 for throttle body mapping and emissions compliance. All ECU work is performed in-house at our Billericay workshop as part of our complete rebuild process.
Yes - the X202 (2008-2012) has distinct engineering from later models. The AJ-V8 uses a different valley pan design than post-2012 models, and the timing chain system has unique tensioner specifications. Our rebuilds use X202-specific components like the reinforced valley pan gasket LR012345 and updated timing chain kit LR096682 to ensure proper fitment and longevity for this specific generation.
