UK USED BUYING GUIDE

LAND ROVER
DISCOVERY SPORT.

The L550 name covers two substantially different vehicles: the original 2015–19 platform and the stiffer, electrified PTA version introduced for 2020. Engine, drivetrain and seating layout must all be identified before inspection.

This quick guide highlights the major risks. Build the detailed guide to remove checks that do not apply to the exact vehicle you are viewing.

BEFORE YOU VIEW

THE DISCOVERY SPORT CHECKS THAT DECIDE THE PURCHASE

DO NOT BUY IT AS “JUST A DISCOVERY SPORT”

Launch cars use the 2.2 SD4. Ingenium diesels arrive for 2016, higher-output diesel and petrol choices follow, then the 2020 PTA rebuild adds MHEV and disconnecting AWD. PHEVs use a three-cylinder petrol engine, eight-speed transmission and electric rear axle—and are five-seat only.

01
2.2 SD4

Prove the timing-belt service and inspect injector/turbo condition

Demand an itemised belt invoice, cold-start for injector-seal leakage and load-test the turbo. This one-year launch powertrain must not be confused with the later Ingenium diesel.

02
INGENIUM DIESEL

Cold-start timing-chain noise is a serious warning

Audit exact oil history, listen for chain and balance-shaft distress, then assess oil dilution, DPF regeneration, EGR, SCR/AdBlue and boost as one system.

03
PHEV

Measure battery health and prove both axles provide drive

Complete AC/DC charging, record usable battery capacity and test engine/EV transitions. The front engine and rear electric drive must coordinate without isolation, cooling or charging faults.

04
NINE-SPEED

Test the ZF 9HP48 cold and fully hot

Check forward/reverse engagement, light-throttle shifts, skip-shifts, kickdown and coast-down. Hesitation, flare or thump needs software, fluid and mechanical diagnosis—not guesswork.

05
AWD

Separate original Haldex-type AWD from PTA Active Driveline

Original cars need PTU, coupling and rear-differential checks. PTA AWD disconnects the rear driveline while cruising and must re-engage cleanly. Matching tyre circumference matters to both.

06
5+2 SEATING

Inspect the third row and the floor beneath it

Raise and latch both occasional seats, test restraints and ventilation, and look for water around the mechanisms. Never accept an aftermarket third row in a PHEV.

07
WATER / ELECTRICS

Lift carpets and scan every module

Roof, windscreen and tailgate water can reach wiring and modules. Test the correct infotainment generation, cameras, powered equipment and ADAS, then look for low-voltage cascades or recently cleared faults.

08
CHASSIS

Check bushes, hubs, brakes, tyres and structure together

Listen for control-arm and bearing noise, inspect inner tyre edges and EPB operation, and check the mixed-material body, subframes and PHEV battery protection for poor repair or impact.
