Hitting the 100,000km mark in your Land Rover Discovery is a milestone worth acknowledging. Whether you're behind the wheel of a Discovery 4 or Discovery 5, reaching six figures on the odometer means it’s time to start thinking differently about maintenance, wear and tear, and long-term reliability.
In this guide, we’ll walk through what Discovery owners can typically expect once their vehicle crosses the 100,000km threshold and how to stay on top of things so your Land Rover keeps performing at its best.
1. Suspension and Steering Components
The Discovery’s air suspension system is one of its standout features, but by the time you hit 100,000km, it’s common to see wear in components like:
- Air suspension compressors
- Height sensors
- Control arms and bushings
- Ball joints and tie rods
Look out for uneven ride height, a sagging rear end, or knocking sounds on bumps. These are early signs something may be wearing out.
2. Transmission and Driveline Health
If your Discovery hasn’t had a transmission service by this point, now’s the time. While Land Rover may not list transmission fluid as “lifetime,” most specialists recommend a flush between 80,000–120,000km. Alongside the transmission, consider inspecting:
- Transfer case fluid
- Differentials (front and rear)
- Driveshafts and CV joints
Sluggish gear changes, noises when turning, or drivetrain vibration can all be symptoms of wear here.
3. Engine Maintenance and Known Issues
For Discovery 4 (with the 2.7L or 3.0L TDV6 engines), 100,000km is a good point to:
- Replace the timing belt if it hasn’t already been done (due every 168,000km or 7 years)
- Check for early signs of EGR valve clogging or turbo boost leaks
- Monitor cooling system components like hoses and the water pump
The Discovery 5’s Ingenium engines also benefit from close attention to oil quality and timely servicing- especially if it's done more towing or off-road work.
4. Brakes, Tyres and Undercarriage
With a 2.5+ tonne curb weight, the Discovery puts a lot of stress on brakes and tyres. After 100,000km, you’ll want to:
- Check brake pad and rotor thickness (rotors may be due for replacement)
- Inspect brake fluid and replace if older than two years
- Inspect for uneven tyre wear or alignment issues
- Look underneath for rust or damage, particularly if it’s seen a lot of beach or track time
5. Electrical Systems and Diagnostics
Modern Discoverys are packed with electronics, and after a few years, you may start to see signs of aging such as:
- Intermittent warning lights
- Sensor errors (especially for parking sensors or TPMS)
- Infotainment glitches or screen issues
Running a diagnostic scan during your service can help spot these early and avoid more expensive repairs later.
6. Interior and Exterior Wear
The Discovery’s interior usually holds up well, but it’s not uncommon to see:
- Wear on driver’s seat bolsters
- Fading touchscreen response
- Minor issues with window regulators or interior trim
Exterior-wise, inspect the tailgate seals, door locks, and underbody panels for signs of wear- especially if it’s been off-road regularly.
Proactive Maintenance is Key
Hitting 100,000km doesn’t mean your Discovery is nearing the end. These vehicles are built to go the distance, but they do best with regular, specialised care. Staying on top of:
- Scheduled servicing
- Fluid replacements
- Genuine parts
- Diagnostic checks
…will keep your Discovery running strong for years to come.
