Stunning looks, but check that belt
The 208 is Peugeot's core supermini and one of the UK's top 10 best-selling cars. The Mk2 (2019+) was a dramatic improvement in design and technology, winning European Car of the Year 2020, and is also available as the fully electric e-208. Used Mk1s (2012-2019) are bargain-priced at £3,000-£7,000 but carry a serious engine risk. Mk2 petrols start around £11,000-£16,000. The 208 outsells the Corsa and Fiesta in some months but sits below both in reliability rankings.
We track 11 known issues across the Peugeot 208 range, including 2 rated as safety-critical. Knowing which variants and configurations to approach with caution can save you from expensive surprises after purchase.

A9 (2012–2021) — Petrol options included the 1.0 VTi, 1.0 PureTech Turbo, 1.2 PureTech, with 1.4 e-HDi, 1.6 e-HDi, 1.5 BlueHDi on the diesel side.
GTi (2012–2019) — Engine options included the 1.6 THP. Our database flags 6 known issues on this generation, 1 of which are rated as safety-critical. The most significant concern is Timing chain tensioner failure (£800–£1,200 to address).
The 1.2 PureTech three-cylinder engine uses a timing belt that runs in an oil bath (wet belt system) instead of the traditional dry belt. This belt is critical for valve timing and drives the oil pump. The belt material degrades in the oil environment and can fail catastrophically without warning, causing immediate engine destruction. When the belt fails, pistons hit open valves causing bent valves, damaged pistons, and requiring complete engine rebuild. This design was abandoned by PSA due to the high failure rate.
Belt failure destroys the engine beyond economical repair within seconds. Pistons hit open valves causing bent valves, damaged pistons, and cracked cylinder head. Complete engine rebuild costs £8,000-£15,000. Many owners elect to scrap the car as repair costs exceed vehicle value. No warning is given before failure.
Listen carefully for a rattle or ticking noise from the engine on cold start — this is the most common early sign. Ask for evidence of chain replacement in the service history. On higher-mileage cars without documented replacement, budget for preventative work.
The 1.6 THP engine (Prince engine co-developed with BMW) suffers from timing chain tensioner failure due to inadequate oil pressure to the tensioner mechanism. The hydraulic tensioner cannot maintain proper chain tension, causing the timing chain to rattle and potentially jump timing. This is a well-documented fault affecting both Peugeot and BMW variants of this engine. Chain jump causes valve-to-piston contact in this interference engine, resulting in catastrophic internal damage.
Tensioner failure leads to timing chain jump causing bent valves, damaged pistons, and destroyed cylinder head. Complete engine rebuild required costing £8,000-£12,000. The engine will stop running immediately if the chain jumps more than one tooth. Chain jump can occur without warning during normal driving.
Listen carefully for a rattle or ticking noise from the engine on cold start — this is the most common early sign. Ask for evidence of chain replacement in the service history. On higher-mileage cars without documented replacement, budget for preventative work.
The 1.5 BlueHDi diesel engine uses a camshaft timing chain that experiences premature stretch due to high combustion loads and oil contamination from DPF regeneration cycles. Chain stretch causes timing drift leading to poor performance, increased emissions, and potential valve timing errors. Unlike the catastrophic wet belt failure on petrol engines, this issue typically develops gradually with warning signs.
Continued chain stretch leads to timing errors causing poor fuel economy, increased emissions, and potential MOT failure. Severe cases can cause valve timing errors leading to valve contact and internal engine damage. Repair involves timing chain replacement and engine timing reset.

The 1.6 THP engine uses a mechanical brake vacuum pump driven from the camshaft to provide brake servo assistance. This pump is prone to failure due to wear of internal diaphragms and seals. Pump failure results in loss of brake servo assistance, requiring significantly more pedal effort to achieve the same braking force. This creates a dangerous situation especially in emergency braking scenarios.
Loss of brake servo assistance makes the brakes much harder to operate, particularly dangerous in emergency situations. While the brakes still function, the increased pedal effort required may prevent effective stopping, especially for drivers with limited strength. This is a safety-critical fault requiring immediate repair.
Check brake disc condition for lipping or scoring. Test braking at moderate speed for pulling to one side or vibration through the steering wheel. Review MOT advisories for brake-related items.
The 1.6 THP engine uses direct injection where fuel is injected directly into the combustion chamber, bypassing the intake valves. This means the intake valves receive no fuel wash to clean them, allowing carbon deposits from crankcase ventilation gases to build up on the valve heads. Carbon buildup restricts airflow causing reduced power, rough idle, and increased fuel consumption. This affects all direct injection engines but is particularly severe on this engine.
Progressive loss of power and fuel economy as carbon buildup worsens. Severe buildup can cause misfiring, rough running, and potential damage to catalytic converter from unburnt fuel. Professional walnut blasting service required to remove deposits without damaging valves.
Listen carefully for a rattle or ticking noise from the engine on cold start — this is the most common early sign. Ask for evidence of chain replacement in the service history. On higher-mileage cars without documented replacement, budget for preventative work.

Based on 944k real DVSA MOT tests, the Peugeot 208 fails more often than average on several items. The biggest outlier is coil springs broken at 38x the fleet average, followed by emissions failure (31x).
When viewing a specific car, check its MOT history for recurring advisories in these categories. See the full Peugeot 208 MOT failure breakdown for data at every mileage point.
Routine servicing (oil and filter change every 10k miles) typically costs £80–£120 at an independent garage.
The bigger-ticket items to budget for include timing belt (wet belt) (£800–£1,200), timing chain inspection (£300–£500).

The Peugeot 208 has some well-documented weak points, including 2 safety-critical issues that demand careful checking. The right example, properly maintained, can still be a sound purchase — but cutting corners on the pre-purchase inspection is not advisable. For Mk1: 2015-2016 with the naturally aspirated 1.2 VTi or 1.0 VTi (NOT the turbocharged PureTech) — these avoid the wet timing belt entirely. For Mk2: 2021+ with the 1.2 PureTech 75 (non-turbo) or the e-208 electric, sidestepping the wet belt issue completely. Never buy any turbo PureTech without proof the timing belt was replaced within the last 4 years or 40,000 miles.
