Peugeot 405 Engine ReplacementCompare Prices & Save

A rebuilt Peugeot 405 engine typically costs £750-£2,400 supply-only, depending on variant and engine code. Supply & fit adds £450-£850 labour. Mi16 and turbo diesel units command premium pricing.

• XUD9 diesel rebuilt: £850-£1,850 supply-only
• XU petrol rebuilt: £750-£2,100 depending on size
• Mi16 XU9J4 rebuilt: £2,200-£4,200 due to complexity
• Supply & fit labour typically adds £450-£850

The XUD9 1.9L diesel is widely regarded as the most robust Peugeot 405 engine when maintained, though injection pump wear is common on high-mileage examples. Petrol XU engines are smooth but more prone to head gasket issues.

• XUD9 diesel: robust block, watch injection pump and head gasket
• XU petrol: smooth but strict timing belt/cooling maintenance essential
• Mi16 XU9J4: high-performance but complex, costly to rebuild
• TU3 1.4L: simple but valve seal wear on high mileage

Peugeot 405 XU petrol engines suffer head gasket failure due to aluminium head/cast-iron block expansion differences under heat; overheating from coolant leaks or failed thermostats accelerates the issue.

• XU engines: aluminium head expands differently to cast-iron block
• Overheating from coolant leaks, failed thermostat or water pump
• Symptoms: white smoke, coolant loss, oil contamination
• Prevention: replace timing belt/water pump every 48k miles

• Rebuilt engine cost: £750-£2,400 vs car value £1,500-£4,000
• XUD diesel engines especially worth rebuilding for high-mileage users
• Mi16 enthusiasts often invest in premium rebuilds for performance retention
• Consider supply & fit cost (£450-£850) if lacking workshop facilities
