1.2L I3 Turbo (EB2DTS)
Petrol
Inspect the timing belt through the oil filler cap using a flashlight, looking for surface cracking, swelling, or fraying on the edges of the belt. | Note: The EB2DTS engine uses a 'wet' timing belt that runs in engine oil. If incorrect oil is used, or oil changes are delayed, the belt degrades. Debris from the degrading belt clogs the oil pump pickup, leading to sudden oil starvation and catastrophic engine failure.
Perform several firm braking maneuvers at low speeds to check if the brake pedal feels unusually stiff, wooden, or lacks power assistance. | Note: Timing belt debris can migrate into the vacuum pump, clogging its oil feed and causing it to seize. This results in an immediate loss of power braking assistance, which was the subject of a global safety recall.
Accelerate heavily from low RPM in a high gear (e.g., 50 km/h in 4th gear) and check for engine hesitation, stuttering, or 'pinging' noises. | Note: These highly-strung direct-injection turbo engines are highly susceptible to Low-Speed Pre-Ignition (LSPI). Using the wrong engine oil or worn spark plugs can trigger LSPI, which easily cracks pistons.
During the test drive, monitor the automatic transmission shifts closely for any shuddering, slipping, or harsh engagement when shifting between 1st, 2nd, and 3rd gears. | Note: The Aisin automatic transmission (EAT6/EAT8) is generally robust but suffers from harsh shifting and valve body wear if the transmission fluid is not regular changed, despite Peugeot claiming it is 'sealed for life'.
Perform a strict annual oil and filter change using only specialist PSA B71 2312 spec oil (0W-30). Inspect the timing belt width using the special PSA gauge tool. Replace spark plugs early to mitigate LSPI risk.
Conduct a comprehensive timing belt inspection. If any cracking or swelling is observed, the timing belt must be replaced immediately, and the engine oil sump pan must be dropped and cleaned. Flush the Aisin automatic gearbox fluid.
Proactively replace the wet timing belt kit, tensioners, and water pump, even if they appear acceptable. Perform a carbon clean of the intake valves (walnut blasting) to restore lost power and smooth out rough idling.
Strictly use engine oil matching PSA B71 2312 or B71 2010 specifications (generic oils will rapidly destroy the wet timing belt).
Inspect the timing belt physical condition and width through the oil filler neck at every single service interval.
Replace spark plugs every 20,000 km or 2 years using only OEM-recommended plugs to prevent pre-ignition issues.
Ensure the oil sump is dropped and the oil pickup strainer screen is cleaned immediately if any timing belt degradation is suspected.
Change the cabin pollen filter annually, as the 308's HVAC system is prone to developing musty odors in damp New Zealand conditions.
Estimated repair costs if issues arise
Essential preventative maintenance to avoid complete engine replacement. Must be done by a Euro specialist with specialized timing tools who will also drop the oil pan to clear belt fibers.
Necessary to cure rough idling and hesitation caused by carbon buildup on the intake valves, a common drawback of direct-injection engines.
If the oil pickup was previously restricted by timing belt debris, the turbocharger bearings are usually the first components to suffer oil starvation and fail.
