Renault Megane service intervals: cambelt, chain and gearbox oil
An overdue cambelt is the most expensive thing a seller can fail to mention on a used Megane. These are the figures UK specialists work to.
Timing belt (cambelt)Belt
1.5 DCI, K9K
72,000 miles or 5 years, whichever comes first
The K9K schedule is 72,000 miles or 5 years, whichever comes first. Intervals vary by variant, with catalogue figures of 150,000 km / 6 years quoted for the Clio 4 with DPF, so the shorter 72,000 miles / 5 years is recorded. The water pump, tensioners and idler pulleys must be replaced simultaneously.
Timing chainChain
1.2 TCE, H5FT
No fixed replacement interval
Chain driven, and known for stretching. The cause is low oil pressure, fuel dilution of the oil and a clogged chain-lubrication oil jet, all made worse by the engine's notorious excessive oil consumption. Replace as a full kit rather than a chain alone.
EDC dual-clutch gearbox oil
6DCT250, DC4
50,000 miles or 5 years, whichever comes first
Renault markets the dry-clutch EDC as sealed for life, but specialists advise an oil change roughly every 80,000-120,000 km (50,000-75,000 miles) or 5-7 years; the shorter end is recorded. The oil degrades and accumulates metallic wear particles, so service sooner on hard or town use.
Always confirm against the vehicle handbook. Intervals vary by engine, and several manufacturers revised theirs after failures in service.

Renault Megane buying questions
Is a used Renault Megane reliable?
The Renault Megane has 3 known faults in our database across 2 generations, 2 of them rated high severity. The most serious are fuel system (delphi high-pressure fuel pump breaks down internally) and gearbox (EDC (Efficient Dual Clutch) automatic transmission juddering and TCM). None of them makes the car a bad buy on its own; the risk is a seller who knows and says nothing.
What are the most common Renault Megane problems?
Three stand out. Fuel system: delphi high-pressure fuel pump breaks down internally (typically 60000 to 120000 miles). Gearbox: EDC (Efficient Dual Clutch) automatic transmission juddering and TCM (typically 40000 to 80000 miles). Suspension: electronic Parking Brake (EPB) module failure or wiring loom breakage causing the handbrake (typically 50000 to 100000 miles). The full list above is grouped by generation, with typical mileage and a rough repair cost for each.
Which Renault Megane years should I avoid?
No Renault Megane year is a write-off, but the 2001-2010 Models (2001 to 2010) carries the most serious faults: fuel system. The 2010-2020 Models (2010 to 2020) has high-severity faults on record too. Year matters less than whether the specific car has had the known fixes, so check the history for them.
What should I check when viewing a used Renault Megane?
Ask the seller about the fuel system, gearbox and suspension faults on this page and whether they have been fixed, with invoices. On the test drive watch for flashing glow plug or engine management light, severe juddering when pulling away and 'Check Parking Brake' warning message. Read the MOT history for repeat advisories, then paste the advert into the free check, which reads it against all 3 known faults before you travel. Check a Renault Megane advert →
What is the real MPG of a Renault Megane?
Owners report 48.1 mpg on average across the Renault Megane engines with data, about 82% of the official combined figure. The gap between official and real-world economy varies a lot by engine, so the Real MPG page lists every engine and generation separately, from 1,623 owner submissions.

If you used to check the Honest John “Good & Bad” section before the site closed in 2026, this page is where that information now lives. We rebuilt the Renault Megane owner-report history from the archived Honest John dataset, added our own research, specialist and owner-club sources and DVSA recall data, and we keep it free. Each fault above is badged with its source. The same data feeds our free advert check, which reads a listing against every known fault for the exact engine and year.
Knowing what a Renault Megane goes wrong with is half of it. The rest is reading the advert and checking the car's history before you hand any money over.
