Range Rover Sport L320 3.0 TDV6 / SDV6 diesel: underbody & corrosion check

Body & chassis · Range Rover Sport L320 (2005–13) · 2009–2013

How often: every year. Subframes, brake pipes and (on the Discovery 3/4 and Sport L320) the steel frame corrode in salty winters.

Work safely: support the vehicle on axle stands, never a jack alone; let it cool first. Check figures against your workshop manual. You do this work at your own risk.

Parts

Cavity wax / underbody protection

Tools

Torch
Pressure washer

Step by step

Wash the underside, then check the subframes, frame rails, brake and fuel pipes, and the rear arches.
