2.0L I4 Turbo (DW10FC)
Diesel
Check the dashboard cluster for 'UREA', 'Service', or 'Engine Fault' warning lights during ignition and the test drive. | Note: The BlueHDi (DW10FC) engine is notorious for AdBlue injector clogging and reservoir pump failures. Replacing the entire pressurized AdBlue tank assembly is extremely common and expensive in New Zealand due to limited parts availability.
Accelerate hard up a steep incline or onto a motorway ramp to test engine responsiveness and watch for black or blue exhaust smoke. | Note: Short-trip urban driving in NZ often causes premature clogging of the Diesel Particulate Filter (DPF) and the EGR valve. If the car hesitates or enters limp mode, a costly manual DPF regeneration or replacement is imminent.
Perform a series of slow stop-and-go maneuvers, paying close attention to downshifts between 3rd, 2nd, and 1st gear. | Note: The EAT6 or EAT8 Aisin automatic transmissions are generally robust but can suffer from rough shifts or shift flares if the transmission fluid has never been changed, despite Peugeot's 'sealed-for-life' claim.
Drive over speed bumps and rough, coarse-chip NZ roads while listening for knocking or creaking from the front axle. | Note: The 2nd Gen 308 commonly suffers from premature wear of the front suspension strut top mounts and lower control arm bushes, aggravated by New Zealand's demanding road topology.
Standard synthetic oil change (must meet PSA B71 2312 spec), oil filter replacement, cabin filter swap, AdBlue system top-up, and diagnostic scan for early emissions faults.
Major diesel service including replacement of the high-pressure fuel filter (vital for NZ diesel quality), engine air filter, brake fluid flush, and a precautionary EAT transmission fluid drain-and-fill.
Critical timing belt and water pump kit replacement (recommended early in NZ due to age/driving conditions rather than Peugeot's optimistic 150,000km limit), Eolys DPF additive fluid top-up, and accessory belt inspection.
Verify that only low-SAPS PSA B71 2312 specification oil (such as Total Quartz Ineo First 0W-30) has been used to protect the SCR catalyst and DPF.
Keep the AdBlue tank regularly topped up using fresh, high-quality ISO 22241 standard fluid to prevent crystallization and pump damage.
Monitor and top up the Eolys DPF additive fluid (patented bag/tank system) at a specialized Euro workshop when warned by the vehicle's computer.
Clean or chemically service the EGR valve every 50,000km to prevent carbon soot buildup from choking the intake manifold.
Inspect the front brake rotors and pads regularly, as the 308's electronic park brake and active braking systems tend to wear rear brakes faster than expected.
Estimated repair costs if issues arise
Required if the heater or pump fails inside the sealed tank module; a very common failure on 2015-2019 Euro 6 BlueHDi models.
Essential preventative maintenance to avoid catastrophic engine damage. Should be done every 6-7 years or 100,000km.
Specialist fluid bag replacement and ECU adaptation required to allow DPF self-cleaning cycles to run.
Highly recommended preventative maintenance to prolong transmission valve body life and ensure smooth shifting.
