and support you can trust.
Range Rover Sport 3.0 SDV6
Engine issue diagnosed properly, options explained clearly, and the replacement unit fitted without drama. Smooth service from start to finish.
Land Rover Discovery 4 3.0 TDV6
Other companies just wanted to sell an engine. Mayfair actually checked compatibility, explained the rebuild route, and delivered exactly what was promised.
Jaguar XF 2.0 Ingenium Diesel
The reconditioned engine has been faultless. Excellent communication, realistic timescales and proper aftercare once the car was back on the road.
Range Rover Velar 2.0 Ingenium
Professional workshop, clear paperwork and no hard sell. They matched the correct engine code and coordinated everything properly.
Jaguar F-PACE 3.0 Supercharged
Rare to find this level of technical knowledge and customer service together. The engine rebuild quality and handover were excellent.
The Land Rover Discovery 5 uses two main diesel units in the UK: the 2.0 litre Ingenium four-cylinder and the 3.0 litre V6. Both pull a heavy 4x4, so towing, town miles and missed oil changes wear them out faster than owners expect. When your Discovery knocks, smokes, loses oil or stops, you need a clear answer and a fair price. Mayfair Rebuilds supplies, rebuilds and fits Land Rover Discovery 5 engines across the UK. We check the fault first, then match the exact engine code, ECU, DPF and emissions setup to your car. You choose a used, reconditioned or rebuilt engine to suit your budget and how long you plan to keep the vehicle. Every unit is stripped, inspected and tested in our own workshop before release. You get up to 12 months warranty, nationwide collection and delivery, and real support before and after the fit.
We cover the full L462 range from 2017 to the latest cars. The Discovery 5 2.0 engine (SD4 Ingenium, code 204DTD) is the common choice for daily drivers and lower mileage use. The Discovery 5 3.0 engine (TD6 and SD6 V6, codes 306DT and 306DTA) suits towing, heavy loads and long motorway runs. Cars from the Discovery 5 2019 model year often carry the 306bhp SD6 with the revised crank and updated DPF, so the correct build year matters when sourcing a unit. Later 2020 cars use the 3.0 straight-six D300 Ingenium. Give us your registration and we confirm the right engine in minutes.

Not every failure needs the same fix, so we offer three routes. Used engines are genuine UK units, compression and leak-down tested, and best for budget repairs. Reconditioned engines have worn parts replaced and are built back to OEM standards, which suits high mileage daily cars. Rebuilt engines are stripped to component level, machined where needed and put back together with new or upgraded parts, then run and tested to factory specification. If you are searching for a Land Rover Discovery 5 for sale as a donor, or need a complete replacement unit, we tell you honestly which option fits your car and your mileage. Pricing is fixed before work starts. No hidden extras.

Our process is simple. First, we assess the symptoms and the failure path. Second, we verify the engine code and platform so the unit fits your gearbox, ECU and emissions layout. Third, we choose the route, used, reconditioned or rebuilt, and prepare or source the engine. Fourth, we supply, fit, test and hand the car back with aftercare guidance. Every engine gets pressure, compression and leak-down testing before it leaves us. Work is done in-house by technicians who only work on Land Rover, Range Rover and Jaguar units. We collect and deliver across the UK mainland. Send your reg for a same-day quote on Land Rover Discovery 5 engines.
