Range Rover Velar P400 Known Issues by Engine

If your Range Rover Velar P400 has the AJ300P (L663 generation):

Range Rover Velar P400 ENGINE OPTIONS

Every Range Rover Velar P400 is different. That's why we offer the right solution for your engine, your car and your budget.

01MOST POPULAR

REBUILDING YOUR RANGE ROVER VELAR P400 ENGINE

Most engine suppliers sell you a used engine of unknown history and hope it matches. We rebuild the engine your Range Rover Velar P400 already has instead - strip it down, pressure-test it, and replace every worn or damaged component (timing chain, injector seals, bearings, gaskets, DC-DC converter) with updated OEM parts. You get a near-new engine with a 12-month unlimited-mileage warranty, without the compatibility risk of an unknown used unit. This is the option most Range Rover Velar P400 owners choose, and it's the one we'd recommend for most situations.

From £3,200
02

RECONDITIONED RANGE ROVER VELAR P400 ENGINES

"Reconditioned" is the term many owners search for when they mean the same thing as a rebuild - a full strip-down, inspection, and replacement of worn parts rather than a straight swap. If that's what you're after, our rebuild service is exactly that.

03

REFURBISHED RANGE ROVER VELAR P400 ENGINES

Similarly, "refurbished" often describes the same process from a different angle - restoring your existing engine to full working condition rather than replacing it outright. Our rebuild covers this.

Learn more
04

REMANUFACTURED RANGE ROVER VELAR P400 ENGINES

Some owners specifically search for a "remanufactured" engine, expecting a unit rebuilt to original specification with updated components. That's consistent with what our rebuild service delivers on the AJ300P.

Learn more
05

REPLACEMENT RANGE ROVER VELAR P400 ENGINES

If your existing engine is beyond economical repair, we also offer full engine replacement and fitting - sourced and fitted by our team, with the same 12-month warranty.

Learn more
06

USED RANGE ROVER VELAR P400 ENGINES

In some cases, a matched low-mileage used engine is the right call - particularly if you need your car back on the road quickly and your existing engine's damage is extensive. We can source and fit these too, though most owners who ask about used engines end up choosing a rebuild once they understand the compatibility risk a used unit carries. Enter your reg below and we'll talk you through both options honestly.

Ask About Used Engine Options

ABOUT THE Range Rover Velar P400 ENGINE

Land Rover engine and vehicle

The Velar P400 is the top-of-the-range non-hybrid petrol model in the Velar line-up. It uses the Ingenium AJ300P - a 3.0-litre inline-six petrol engine fitted since the Velar's launch in 2017. It sits above the P340 in the petrol range, offering the highest output among the non-hybrid petrol Velar options, with the P400e PHEV sitting above it as the plug-in hybrid flagship.

We continue to rebuild and replace AJ300P engines for every Range Rover Velar P400 on the road.

Range Rover Velar P400 ENGINE CODES

A 3.0-litre inline-six petrol fitted to the Velar P400 from 2017 to present (L560 generation). Generally reliable with no specific pattern of catastrophic failure - cooling system issues are occasionally noted in specialist circles, but there's no established pattern equivalent to the timing chain concerns seen on the Ingenium diesel range. We replace timing chains, bearings, water pump and gaskets as standard on every rebuild.

Range Rover Velar P400 ENGINE COMPATIBILITY

Land Rover Land Rover vehicle in workshop

The Velar P400 uses a single engine family across its entire production run - the Ingenium AJ300P petrol inline-six - so there's no generation-specific engine mismatch risk when we're working on this variant. However, there are ancillaries and ECU variations that differ by build year, so we still confirm your exact spec via registration before quoting or supplying parts. This protects you from any minor compatibility surprises that aren't obvious from the model badge alone.

Your exact engine code (AJ300P) via registration or VIN

Your generation (L663)

Drivetrain and ancillary specification

Whether your build falls in the early production period (2019-2020) for injector fault coverage

This is why we always start with your registration rather than a generic Defender quote - it protects you from paying for parts that don't fit your actual car.
