1.2L I3 (EB2ADTS)
Petrol
Remove the oil filler cap and use a torch to inspect the exposed section of the timing belt for cracking, swelling, or fraying edges. | Note: The EB2ADTS engine features a 'wet' timing belt that runs in engine oil. The belt can degrade prematurely, shedding rubber particles that clog the oil pickup strainer, leading to oil starvation and engine failure.
Perform several firm braking maneuvers at low speeds in a safe area to check for a stiff or unresponsive brake pedal. | Note: When the timing belt degrades, rubber debris often blocks the vacuum pump oil feed. This can cause a sudden loss of brake assist, which has been the subject of safety recalls globally and in New Zealand.
Accelerate firmly up a steep hill or in a high gear at low RPM (around 1,500 - 2,000 RPM) to test for engine hesitation, stuttering, or a flashing check engine light. | Note: This direct-injection turbo engine is susceptible to Low-Speed Pre-Ignition (LSPI) and rapid spark plug wear. Hesitation under high-load, low-RPM conditions indicates ignition or carbon build-up issues.
Conduct a series of stop-and-go maneuvers, paying close attention to any jerking, lagging, or clunking from the EAT8 automatic transmission during low-speed downshifts. | Note: While the Aisin-sourced 8-speed automatic is generally reliable, it requires clean fluid. Jerkiness is often resolved with a software update or a transmission fluid flush, which is frequently neglected under 'lifetime' service claims.
First major service. Ensure strict use of PSA B71 2010 (0W-20) spec oil to preserve the wet timing belt. Check cabin filter and perform a diagnostic scan for any engine control module (ECU) updates.
Crucial milestone. Inspect the timing belt width using the official Peugeot gauge tool. Replace the high-sensitivity spark plugs and the brake fluid. Inspect front brake pads and rotors for wear.
Major preventive maintenance. Replace the timing belt, tensioners, and water pump. It is highly recommended to drop the oil sump and clean the oil pickup strainer of any accumulated belt debris. Inspect the Gasoline Particulate Filter (GPF).
Strictly use engine oil matching the PSA B71 2010 (0W-20) standard; incorrect oil chemistry rapidly destroys the wet timing belt.
Inspect the timing belt condition through the oil filler neck at every oil change interval.
Shorten oil change intervals to every 10,000 km or 12 months, ignoring the longer European factory recommendations to mitigate NZ's stop-start driving conditions.
Perform an intake valve carbon clean (walnut blasting) every 50,000 km to combat direct-injection carbon build-up.
Check the brake vacuum pump inlet nozzle for rubber debris whenever the timing belt shows signs of surface wear.
Estimated repair costs if issues arise
Preventative replacement to avoid catastrophic engine failure. Must include dropping the oil sump to clean the oil pickup strainer of belt debris.
Recommended if the vehicle suffers from rough idling, power loss, or persistent misfires due to carbon build-up on the intake valves.
The EB2ADTS is highly sensitive to plug wear. Use only premium OEM-spec plugs gapped correctly to prevent LSPI damage.
