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

If your Jaguar XF has lost power, started knocking, or stopped and will not restart, a repair may not be worth the money. Mayfair Rebuilds sells used, reconditioned and rebuilt Jaguar XF engines for petrol and diesel models, with supply and fit across the UK.
Every Jaguar XF engine for sale in our stock is matched to your car by engine code and VIN before we quote, so the unit fits and runs as it should. We strip, inspect and rebuild engines in our own UK workshop, and each one is tested before it leaves us.
You get honest advice, a fixed quote, and a warranty of up to 12 months. We handle collection, fitting and aftercare, so you deal with one team throughout. Send your reg and we will tell you which engine fits, which route suits it best, and what the job involves.
We sell three types of replacement engine for the XF, so you can pick the one that suits your budget and the damage. Both generations are covered: the X250 (2008 to 2015) and the X260 (2015 onwards). Engine codes we work with include 204DT, 204DTA, 204DTD and 224DT diesels, AJD, 306DT and AJV6D V6 diesels, and the 204PT, AJ126 and AJ133 petrol units.
Every engine we sell comes with a warranty of up to 12 months, based on the route you choose. We collect and deliver across the UK mainland, so you can fit the engine yourself, or let our team handle the full supply and fit job. Before we quote, we check the engine code, condition grade and stock, then give you one fixed quote with no hidden extras. We fit genuine or OEM-quality parts only, and every engine is pressure, compression and leak-down tested before it leaves our workshop. We also advise on supporting parts your XF may need, such as the water pump, turbo oil feed or cooling parts.
These are the Jaguar XF faults we see most in the UK, what causes them, and the fix we supply.
