1.6L I4 Turbo (EP6CDTR)
Petrol
Execute a hard acceleration run in 3rd gear from 2,000 rpm up to the redline to check for hesitations, stuttering, or 'half-engine' warning lights. | Note: The High-Pressure Fuel Pump (HPFP) is a notorious weak point on the EP6CDTR. Stuttering under load is a primary symptom of a failing pump, which is expensive to source in New Zealand.
Perform a series of moderate to firm braking maneuvers on a smooth road, feeling for any pedal pulsation, steering wheel vibration, or squealing. | Note: The RCZ R features massive 380mm Alcon front brake discs on aluminum bells. Replacement rotors and pads are motorsport-grade, rarely stocked in NZ, and cost an absolute fortune to import and replace via authorized networks.
Conduct a cold start of the vehicle after it has been sitting for at least 4 hours, listening closely to the left side of the engine bay as you face it (the driver's side) for a metallic rattling sound. | Note: Timing chain stretch and tensioner failure are common Prince engine issues. While the 270hp R version received upgraded components, neglected oil changes still lead to chain slack and eventual engine failure.
Park up after a warm test drive, pop the bonnet, and inspect the turbocharger area for any coolant leaks, crusty residue, or the smell of burning oil. | Note: The auxiliary electric water pump (which cools the turbo after shutdown) and the turbo oil feed pipes are prone to leaking and heat-cracking due to the extreme thermal loads of the 199kW tune.
Replace the high-performance NGK spark plugs (specific to the R) and perform a strict oil change using PSA B71 2312 certified 0W-30 oil. Inspect the front Alcon brake pads for wear.
Perform a manual gearbox oil flush to protect the Torsen limited-slip differential. Inspect the intake valves for carbon buildup (typical of direct-injection) and perform walnut blasting if required.
Undertake a major preventative service: replace the timing chain, tensioner, and guides. Replace the auxiliary turbo water pump and thermostat housing, and inspect the health of the bypass valve.
Always run the vehicle on high-quality 98 Octane fuel (e.g., BP Ultimate) to prevent Low-Speed Pre-Ignition (LSPI) and carbon fouling.
Maintain a strict engine oil change interval of 5,000km to 7,500km or 12 months using only Total Quartz Ineo First 0W-30.
Regularly monitor coolant levels; the plastic thermostat housing is known to warp and leak, leading to rapid overheating.
Check the Alcon brake calipers regularly for dirt buildup, ensuring the sliding pins and pistons move freely to prevent uneven pad wear.
Ensure the fixed rear spoiler mounts are inspected for clear coat peeling, hairline stress cracks, and potential water ingress into the boot floor area.
Estimated repair costs if issues arise
Highly specialized semi-floating racing brakes. Sourcing them from official NZ dealer networks requires direct import from Europe with severe markup. Budget heavily for these specialized components.
A failure will put the car into limp mode. Local NZ Peugeot dealer pricing is extremely high; many owners self-import OEM Continental/PSA parts to save on markup.
Preventative replacement is highly recommended if history is unknown. Must be done by a European specialist with the correct PSA timing locking tools.
