Renaultsport Mégane 280 / 300 buying guide
The last Mégane RS, launched in 2018 as the RS 280 with a 1.8 turbo and four-wheel steering, later uprated to the RS 300 and Trophy. Manual and EDC dual-clutch versions were sold, with Sport and firmer Cup chassis. Its known points are few and specific.
The versions
- 1.8 turbo four-cylinder: 276bhp in the RS 280, 296hp in the RS 300 and Trophy
- Six-speed manual or six-speed EDC dual-clutch automatic
- Sport chassis without a limited-slip differential, or Cup chassis with a Torsen limited-slip differential and firmer springs, dampers and anti-roll bar
- 4Control four-wheel steering; the Trophy adds 19in wheels, a lithium-ion battery and upgraded brakes
- Facelift in late 2020 with updated infotainment and physical climate buttons
What to check on a Mégane RS 280 / 300
3 model-specific things to look at when you view one. They're a starting point, not the full inspection.
Oil pressure solenoid on 2019 builds
What to look for: Check the build date. On a car built from March to May 2019, ask for paperwork showing the replacement oil pressure solenoid was fitted.
Why it matters: Cars built between March and May 2019 could have a faulty oil pressure solenoid, and a replacement part was fitted to affected cars. Paperwork confirming it is the thing to see.
Gearbox warnings and shift quality
What to look for: On an EDC car, drive long enough to cover town and open road and watch for a "check auto gearbox" warning or jerky changes. On a manual, note how the lever moves between gears, particularly from first to third.
Why it matters: A "check auto gearbox" warning is a serious fault on the EDC, and at least one car needed a new gearbox unit. The manual can feel clunky and imprecise, with an obstructive first to third shift when new, which reportedly improves with mileage.
The Trophy's lithium battery
What to look for: On a Trophy, ask whether the car has been left standing, whether the battery has ever gone flat or been replaced, and whether the owner uses a suitable battery conditioner. Watch for warning lights at start-up.
Why it matters: The Trophy's lightweight lithium battery goes flat if the car sits unused, and incorrect jump starting can damage it. A standard battery can't simply be fitted in its place. Renault's software update didn't always cure it, and several batteries were replaced under warranty.
