How much does a Land Rover Velar P400 engine replacement cost in the UK?

A reconditioned AJ20P6 engine typically costs £4,500–£7,000 supply only, with the same engine used across the Velar, Range Rover, and Range Rover Sport ranges. Fitting adds £1,000–£1,500. Use our calculator for a figure specific to your vehicle.

Is the Velar P400 engine reliable?

The AJ20P6 straight-six Ingenium petrol is considered significantly more reliable than the diesel AJ20D6. It's rated ★★★★☆ based on current data, but cooling system maintenance — particularly the water pump — is the key to longevity. No catastrophic design flaws have emerged.

What are the common problems with the Velar P400?

Water pump failure, coolant crossover pipe leaks, and occasional timing chain tensioner wear are the most common issues. None typically lead to full engine replacement if caught early — preventative cooling system maintenance is the priority.

Is it worth replacing a Velar P400 engine, or should I scrap the car?

Against a £20,000–£40,000 Velar P400, a £5,500 recon engine is a manageable 14–28% of the vehicle's value — worth it for a well-maintained example. Given the Velar's strong retained values, replacement is usually viable. Scrap only if the vehicle has suffered catastrophic damage well beyond the engine.

How do I find my Velar's engine code?

For the P400, the engine code is AJ20P6 — it's on the VIN plate and vehicle documentation. The P400 badge signifies the 3.0-litre turbocharged petrol Ingenium. If you're unsure, tell us your registration date and we'll confirm it for free.

Can I repair the AJ20P6's water pump, or does it need a new engine?

Yes — the water pump is a straightforward repair costing £500–£1,000. The AJ20P6's water pump is the most common service item on this engine; replacing it as a preventative measure at 60,000 miles is strongly recommended.

Buying This Velar P400? Check These First

Buy If

Full Land Rover service history with documented oil-change intervals
Water pump replaced at or before 60,000 miles as a preventative measure
Coolant crossover pipes inspected for signs of brittleness or leaks
Post-2022 build with any early cooling system software updates applied

Avoid If

Service history shows repeated coolant top-ups with no diagnosis
Any evidence of overheating — check the service records for head gasket work
No record of cooling system maintenance on higher-mileage examples (60k+)
Engine warning light present with no diagnosis documentation

Closing Verdict

The Velar P400's AJ20P6 is JLR's most refined 3.0 petrol yet — a genuine step forward from the AJ126 supercharged V6. But like all modern engines, it demands the right cooling system maintenance. Buy on service history and proof of water pump replacement. If you're replacing, a reconditioned unit with a 12-month warranty is the sweet spot.

Buying Checklist

Before you buy a used Land Rover Velar P400 (or before you commit to an engine replacement), check these:

Cold Start — Listen for any rattle on startup (timing chain tensioner wear)

Service History — Including which engine era (AJ20P6 is the only P400 engine — verify this before purchase)

Coolant Level — Is the coolant low with no visible leak? Potential water pump or crossover pipe issue

Turbo Boost — Test acceleration; any hesitation, lag, or whistling?

Cooling System Check — Has the water pump been replaced? This is the number‑one preventative item

Oil Consumption — Does it use more than 1L per 5,000 miles? If so, investigate

Engine Warning Light — Have codes been read? Any unresolved cooling or fuelling issues?

MOT History — Check for emissions-related failures; the P400 should pass easily if well‑maintained
