Renault Megane 1.2 TCE Engine ReplacementCompare Prices & Get Quotes

A Renault Megane 1.2 TCE engine replacement typically costs £1,200-£2,800 for a reconditioned H5F unit supply-only, with used engines from £600-£1,600. Fitting adds approximately 6-10 hours of labour at specialist rates. Main dealer prices are typically 40-60% higher. The exact cost depends on your engine code - H5F 408 (115bhp) or H5F 412 (130bhp) - and the extent of any auxiliary damage.

• Used engine: £600-£1,600
• Reconditioned engine: £1,200-£2,800
• Supply & fit: £2,000-£4,000+ depending on condition

The classic warning sign is a metallic rattle or chatter from the timing cover on cold start that lasts a second or two. If the rattle persists when warm, lasts longer than a couple of seconds, or gets louder with revs, it's more concerning. Other symptoms include rough idle, hesitation, poor fuel economy, engine warning lights (P0011/P0016 codes), and hard starting. In worst cases, the chain can snap, causing catastrophic valve and piston damage.

• Cold-start rattle from timing cover - first warning sign
• Rough idle, hesitation, loss of power
• Engine warning light with cam/crank correlation codes
• If you hear rattle, get it inspected immediately

It depends on your Megane 1.2 TCE's overall condition and value. A Renault Megane 1.2 TCE (2012-2018) is typically worth £5,000-£12,000. A reconditioned engine supply and fit costs £2,000-£4,000. For a Megane 1.2 TCE worth over £5,000, replacement is usually worthwhile, especially with a 12-month warranty. For examples under £4,000 with significant body or suspension wear, evaluate carefully.

• Vehicle worth £5,000+: reconditioned replacement usually makes sense
• Vehicle worth £3,000-£5,000: compare used vs reconditioned carefully
• Vehicle worth under £3,000: evaluate scrap value first

A Renault Megane 1.2 TCE engine replacement typically takes 6-10 hours of labour at a specialist workshop. Allow 3-5 working days for the full supply-and-fit process, including delivery of the replacement unit. Specialists often offer faster turnaround than main dealers due to their focus on these engines.

• 6-10 hours labour at specialist rates
• Supply & fit typically completed within 5 working days
• Specialist workshops often faster than main dealers

The 1.2 TCE uses a timing chain, not a belt. The chain is claimed to last the life of the car, but in practice it's a known weak point on this engine. Timing chain stretch and tensioner failure are common if oil changes are neglected. Oil changes are critical to chain and tensioner life - every 10,000 miles or annually.

• 1.2 TCE: timing chain (not belt)
• Chain and tensioner wear is common
• Regular oil changes are critical to chain life

Both use the same 1,197cc H5F engine family. The 115bhp version (H5F 408) produces 115bhp at 4,500rpm and 190Nm torque. The 130bhp version (H5F 412) produces 130bhp (132PS) at 97kW with 205Nm torque. The 130bhp variant was introduced in 2013 and became the standard engine for higher-spec Megane IV models. Both share the same timing chain vulnerabilities.

• 115bhp: H5F 408, 2012-2015, Megane III
• 130bhp: H5F 412, 2013-2018, Megane IV
• Both have the same known timing chain issues

You can, but it requires careful checking. Swapping between H5F variants (e.g., H5F 408 to H5F 412) may require ECU reprogramming to match the different mapping. Some variants have different emissions standards (Euro 5 vs Euro 6) which can affect MOT compliance. Always use a specialist for the swap to ensure correct ECU calibration and immobiliser pairing.

• Check engine code compatibility before ordering
• ECU remap may be required for different power outputs
• Emissions compliance must be verified for MOT

Every reconditioned Renault Megane 1.2 TCE H5F engine supplied through EnginesMarket carries a minimum 12-month unlimited-mileage warranty. Used engines typically come with a shorter warranty (30-90 days) depending on the supplier - always confirm the warranty terms before purchasing. Rebuilt engines also include upgraded timing chain kits and components where applicable, addressing the original failure points.

• Rebuilt engines: 12-month unlimited-mileage warranty minimum
• Reconditioned engines: 12-month warranty typical
• Used engines: 30-90 day warranty (check with supplier)
