1.6L PHEV (EP6FDT)
Plug-in Hybrid
Perform multiple full-throttle accelerations from a standstill to force the internal combustion engine (ICE) to take over from EV mode. | Note: The transition from electric to petrol engine power should be smooth; any prominent hesitation, shuddering, or 'thump' suggests an e-EAT8 wet-clutch software calibration fault.
Test all functions of the i-Cockpit infotainment unit, including the 360-degree reversing camera system and hybrid power-flow screens. | Note: Early R83 plug-in hybrid models are prone to infotainment module system lag, blackouts, or camera freezing; ensure the latest dealership firmware updates are present.
Open the bonnet, perform a cold start, and listen for any distinct metallic ticking or rattling sounds from the timing chain area. | Note: While improved in the EP6FDT hybrid application, the underlying Prince engine architecture can still suffer from premature timing chain tensioner fatigue.
Cycle the electronic parking brake on and off repeatedly and perform low-speed regenerative braking stops down a hill. | Note: Listen for grinding or clunking from the rear axle; the added weight of the hybrid battery pack puts substantial extra load on the rear brake calipers and suspension mounts.
Initial major diagnostic scan of the high-voltage hybrid control module and standard low-viscosity 0W-20 (PSA B71 2010) oil change service.
Critical spark plug replacement interval and complete brake fluid flush. Inspect both separate dual-cooling systems (one for ICE, one for battery/inverter).
Major hybrid service milestone: accessory drive belt replacement, thorough timing chain wear inspection, and a certified High-Voltage battery State of Health (SOH) scan.
Verify absolute use of ultra-low viscosity PSA B71 2010 specific engine oil to prevent catastrophic Low-Speed Pre-Ignition (LSPI) events.
Inspect the AC charging port housing, clean out debris, and check that the electronic locking pin engages and releases smoothly.
Check for heavy carbon crusting on the intake valves, which is common on direct-injection engines that frequently run short cycles.
Inspect the electronic active suspension dampers for fluid leaks (GT trims); these electronically controlled shocks are highly expensive to replace.
Check tire sidewalls carefully to ensure they have the proper 'Extra Load' (XL) load rating required to carry the PHEV's heavy curb weight.
Estimated repair costs if issues arise
Extremely high cost; always verify the remaining balance of Peugeot's 8-year/160,000km factory hybrid battery warranty before purchasing.
The internal 7.4kW AC charging unit can burn out, preventing the car from accepting plug-in power; a known failure point on early PHEV models.
Preventative replacement is highly recommended if a cold start rattle develops; includes upgraded guides, tensioner, and front main seal.
