On the 2005-2024 Land Rover Discovery, the Discovery is notorious for water leaks through blocked sunroof drains and deteriorated A-pillar seals. Water enters the cabin through the headliner and runs down the A-pillars, pooling in the front footwells. On LR3/LR4 models, this can damage the BECM (body electronics control module) located under the driver seat. The twin sunroof design with extra-long drain tubes is particularly prone to blockage.

Common Symptoms

Water dripping from headliner or A-pillars
Wet carpets in footwells after rain
Musty smell in cabin
Electrical faults from wet BECM
Water stains on headliner

How to Fix

Clear all four sunroof drain tubes with compressed air. Replace the A-pillar seals if worn. Apply butyl sealant around the sunroof frame. For severe cases, inspect and protect the BECM with a waterproof cover. Some owners install drain tube extensions to route water further from the body.

On the 2017-2025 Land Rover Discovery, the current-generation L462 Discovery continues the air suspension tradition with its own set of issues. The ride height sensors are particularly prone to failure, giving incorrect height readings that cause the vehicle to sit at uneven heights. The sensors are located at each corner and exposed to road debris. Failure of one sensor affects the entire system's ability to level the vehicle.

This issue also affects: Infiniti QX60, Jaguar XJ, Land Rover Range Rover

Common Symptoms

Vehicle sitting at different heights side to side
Suspension fault warning
Ride height adjustment not working
Vehicle leans to one side
Harsh ride quality

How to Fix

Replace the faulty ride height sensor(s). These are accessible at each wheel without lifting the vehicle significantly. Recalibrate the air suspension system using JLR Pathfinder diagnostics after sensor replacement.

Parts and tips from 680+ owners who fixed this issue

TipThe height sensor links are cheap plastic and break easily. Keep a spare in the glovebox — a broken link gives the same symptoms as a bad sensor.

Typical repair cost:$300 - $800
