2.0L BlueHDi (DW10FC)
Diesel
Turn on the ignition and check the instrument cluster for any active AdBlue/UREA lights or 'Engine fault: Repair needed' warnings. | Note: The BlueHDi emissions equipment in the DW10FC engine is highly prone to AdBlue tank pump failures and injector crystallization, resulting in expensive repair bills.
Cycle the EAT8 automatic transmission through all 8 gears under moderate acceleration, watching for hesitations between 2nd, 3rd, and 4th. | Note: The Aisin EAT8 gearbox is generally robust, but software glitches or fluid degradation can cause jerky shifts. Do not trust Peugeot's 'sealed for life' claim.
Operate the full i-Cockpit infotainment screen, testing Apple CarPlay, Android Auto connectivity, and the factory GPS mapping software. | Note: The central NAC infotainment screen can suffer from hardware internal memory degradation. Freezing or slow response to touch inputs usually requires a full firmware reinstall.
Drive over speed bumps or uneven roads at low speed and listen for sharp knocking or clunking noises from the front suspension. | Note: Front suspension control arm bushings and top strut mounts on the Second Gen 508 can wear down prematurely under harsh road conditions, ruining ride refinement.
Initial major inspection: engine oil and filter change using exclusive PSA B71 2312 specification fluid, cabin filter change, and full AdBlue top-up.
Intermediate diesel service: replacement of the air filter and main fuel filter (highly critical). NZ experts recommend a preventative EAT8 transmission oil drain and fill.
Critical service milestone: complete timing belt and water pump replacement. While factory guidelines allow longer intervals, NZ stop-start driving makes 100k the safe limit.
Verify strict use of 0W-30 low-ash synthetic oil meeting PSA B71 2312 standards to protect the complex Diesel Particulate Filter (DPF).
Inspect the DPF soot and ash loading levels via a professional OBD2 diagnostic scanner to check filter life.
Check the AdBlue injector tip located in the exhaust stream for white crystalline urea buildup around the port.
Lubricate the panoramic sunroof seals and guide mechanisms (if equipped) to prevent motor strain, binding, or annoying wind noises.
Check front brake rotor thickness; modern Peugeot brake discs are quite soft and almost always require replacement whenever changing pads.
Estimated repair costs if issues arise
High labor costs due to tight packaging inside the low-slung engine bay of the second-generation 508 chassis.
Very common failure point where the internal delivery pump fails inside the sealed tank, requiring a complete replacement tank unit.
Highly necessary if the vehicle has spent its life doing short city commutes in Auckland without regular high-speed motorway clearing runs.
