Renault Megane ETech PHEV Engine Replacement - Compare Prices & Get Quotes

A replacement H4M 630 engine for a Renault Megane E-Tech PHEV typically costs £2,000-£4,500 for the supply-only unit. Fitting adds 10-14 hours of labour at £65-£90/hr, bringing the total fitted cost to £3,000-£5,500 at an independent specialist. Dealer pricing is significantly higher, with some owners reporting quotes in the £5,000-£8,000 range for a full replacement.

• Used engine supply: £2,000-£3,000
• Reconditioned supply: £3,000-£3,800
• Rebuilt supply: £3,800-£4,500
• Gearbox/electric motor replacement (if required): additional £2,500-£4,500

The most common sign is a clunky or jerky transition between petrol and electric power, particularly at around 30mph. More serious symptoms include drivetrain noise, loss of power, warning lights, and complete transmission failure. Some owners have reported gearbox failure at mileages as low as 29,000 miles.

• Clunky shifts and jerky transitions are early warning signs
• Drivetrain noise or vibration indicates more serious mechanical issues
• Complete failure requires gearbox and/or electric motor replacement

The E-Tech PHEV is relatively new, so long-term reliability data is limited. The 1.6-litre petrol engine itself is a proven unit, but the complex hybrid gearbox has been a source of complaints. Some owners report trouble-free ownership, while others have experienced significant drivetrain issues at relatively low mileages.

• The petrol engine is generally robust and reliable
• The gearbox and electric motor are the primary areas of concern
• The 9.8 kWh battery carries an 8-year/100,000-mile warranty

It depends on the vehicle's value. Early examples (2020-2021) are worth £11,000-£18,000 - a full engine replacement at £3,000-£5,500 may represent 20-40% of the car's value, which is often justifiable if the rest of the car is in good condition. However, if the gearbox and electric motor have also failed, total repair costs can exceed £7,000, making replacement uneconomical.

• Evaluate the total repair cost vs. the vehicle's current market value
• Consider part-exchange or selling for spares if repair costs exceed 60% of value
• Always get multiple quotes before committing

The Megane E-Tech PHEV (plug-in hybrid) combines a 1.6-litre petrol engine with two electric motors and a 9.8 kWh battery, offering up to 30 miles of pure-electric range. The Megane E-Tech Electric is a fully electric vehicle with a 40kWh or 60kWh battery and no combustion engine. They are completely different vehicles with different platforms and powertrains.

• PHEV: 1.6 petrol + electric motor + 9.8 kWh battery; 160hp; 30-mile EV range
• EV: 100% electric; 40kWh or 60kWh battery; 220hp; up to 292-mile range
• Check your registration to confirm your exact vehicle type

The 9.8 kWh battery takes approximately three hours to charge from zero to 100% using a Type 2 charger, or just over four hours using a domestic three-pin socket. The onboard charger operates at up to 3.6kW.

• Type 2 charger: ~3 hours for a full charge
• Domestic 3-pin socket: ~4+ hours for a full charge
• The battery warranty covers 8 years or 100,000 miles
