Your Land Rover 204DTA engine fails. We fix it. Mayfair Rebuilds supplies, rebuilds and replaces 204DTA engines across the UK: fault diagnosis, engine code matching, supply and fit, all handled by our own technicians in our UK workshop. Every engine is stripped, tested and built in-house. You get fair pricing with no hidden costs, expert support before and after fitment, and up to 12 months warranty. That is why UK drivers trust us with their Land Rover 204DTA engine work.
The 204DTA is a 2.0-litre twin-turbo diesel from the Jaguar Land Rover Ingenium family. It fits the Discovery Sport, Discovery 5, Range Rover Sport, Range Rover Velar and Range Rover Evoque. It gives strong power and good fuel economy, but it has weak points. Timing chain wear, oil dilution and turbo failure are common, often between 60,000 and 100,000 miles. We manage the entire engine replacement process under one roof, offering professional in house supply and fit services alongside nationwide mainland UK engine delivery option. Every replacement unit is backed by up to 12 months warranty, giving Land Rover owners complete peace of mind and lasting reliability. Just put your registration on the website to get a free price quote and give your vehicle the best engine service that it deserves and go back with complete confidence.
We offer three practical engine replacement routes tailored to your vehicle condition, budget, and driving requirements. Our fully rebuilt 204DTA engines undergo complete component-level strip-downs in our dedicated workshop facility. Technicians inspect the aluminium block, machine the crank and cylinder bores, and install brand-new timing chains, revised tensioners, new crankshaft bearings, fresh piston rings, and new oil seals.
For drivers seeking strong reliability at a balanced price, our reconditioned units feature full ultrasonic cleaning and the replacement of all worn mechanical parts before undergoing rigorous pressure and compression tests. We also supply low-mileage, tested used 204DTA units sourced from trusted UK channels. Each used unit undergoes thorough leak-down checks and bore inspections, ensuring a road-ready unit ready for immediate dispatch or installation.
Replacing an Ingenium 204DTA unit demands specialist technical tools, exact timing alignment, and proper electronic system integration. Our end-to-end supply and fit service removes the stress of engine failure by managing every stage of the replacement. If your vehicle is non-running or immobilised, our dedicated transport team arranges vehicle collection from your home or local garage to our workshop.
Once inside our facility, experienced technicians remove the defective unit, chemically flush the oil cooler lines, inspect the twin turbochargers, and install your replacement engine using factory torque procedures. We complete vital Land Rover diagnostic coding, calibrate fuel injectors, configure adaptations, and complete intensive road-testing before vehicle handover. Alternatively, trade customers can order crated units for fast UK-wide delivery.
