Lightweight pocket rocket with cult following
The Peugeot 106 is a much-loved supermini that served as affordable, cheerful urban transport throughout the 1990s and early 2000s. The GTi version earned a cult following as one of the best hot hatches ever made, while base models were honest, economical runabouts. It appeals to first-time drivers, budget buyers, and enthusiasts seeking a lightweight, analogue driving experience.
We track 5 known issues across the Peugeot 106 range, including 4 rated as safety-critical. Knowing which variants and configurations to approach with caution can save you from expensive surprises after purchase.

106_Phase1 (1991–1996) — Petrol options included the 1.0 8v, 1.1 8v, 1.3 8v, 1.4 8v, 1.6 8v/16v, with 1.5 D on the diesel side. Our database flags 5 known issues on this generation, 4 of which are rated as safety-critical. The most significant concern is Structural corrosion compromising vehicle rigidity (£800–£2,000 to address).
106_Phase2 (1996–2004) — Petrol options included the 1.1 8v, 1.4 8v, 1.6 16v, with 1.5 D on the diesel side. Our database flags 5 known issues on this generation, 4 of which are rated as safety-critical. The most significant concern is Structural corrosion compromising vehicle rigidity (£800–£2,000 to address).
The 106's monocoque structure is prone to serious corrosion that weakens the load-bearing shell, particularly around suspension mounting points and structural joints. MOT data shows this model fails at 58.6 times the fleet average for structural rigidity defects, with failures documented across all engine variants and mileage bands. The thin steel construction and basic anti-corrosion treatment make this a progressive issue that can render the vehicle unsafe. This is distinct from cosmetic surface rust and represents a fundamental structural weakness.
Structural corrosion can lead to catastrophic failure of suspension mounting points or loss of chassis rigidity, making the car dangerous to drive and potentially causing loss of control. Extensive welding repairs typically cost £1,500-£3,000 but may exceed the car's value. Many examples become uneconomical to repair.
Inspect the wheel arches, sills, jacking points and door bottoms carefully. Press gently on sills to check for soft spots. Look underneath for corrosion on structural components. Check the MOT history for corrosion-related advisories or failures.
The 106 suffers from widespread brake efficiency problems affecting both individual wheel performance and overall system effectiveness. MOT data shows brake effort inadequacy failures at 124.6 times the fleet average and system efficiency below minimum requirements at 62 times the average. The issue stems from caliper seizure, brake line corrosion, and master cylinder deterioration. This affects all variants and mileage ranges, indicating a fundamental design weakness in the brake system components and materials used.
Brake system failure creates an immediate safety risk and can result in inability to stop the vehicle. Seized calipers cause uneven braking and potential loss of control. Complete brake system renovation including calipers, lines, and master cylinder typically costs £400-£800. The vehicle should not be driven with suspected brake efficiency problems.
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 rear axle beam mounting system develops excessive movement between the stub axle and beam assembly, with MOT failures at 128.7 times the fleet average on 1.1-litre models at high mileage. This indicates failure of the torsion beam bearings or mounting bushes that allow the semi-independent rear suspension to articulate. The fault creates dangerous handling characteristics and can lead to loss of rear wheel control during cornering or braking. The issue is most prevalent on higher-mileage examples where bearing wear has progressed.
Excessive rear axle movement creates dangerous handling characteristics and can cause loss of vehicle control, particularly during emergency braking or cornering. The rear wheels may adopt incorrect geometry leading to rapid tyre wear. Repair requires rear axle beam replacement or rebuild, typically costing £300-£600. The vehicle should not be driven if rear axle movement is suspected.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.
The load-bearing structure within 30cm of steering component mounting points suffers significant corrosion, with MOT failures at 60.7 times the fleet average. This affects the areas where the steering rack and associated components attach to the body shell or subframe. Corrosion in these 'prescribed areas' is classified as dangerous because it can lead to steering component detachment and immediate loss of vehicle control. The thin steel construction and poor corrosion protection make this a critical safety issue on higher-mileage examples.
Corrosion of steering component mounting areas creates an immediate safety risk and can result in steering failure and loss of vehicle control. This is classified as a dangerous defect requiring immediate repair before the vehicle can be driven. Structural welding and reinforcement typically costs £300-£800 but may render the vehicle uneconomical to repair.
Inspect the wheel arches, sills, jacking points and door bottoms carefully. Press gently on sills to check for soft spots. Look underneath for corrosion on structural components. Check the MOT history for corrosion-related advisories or failures.
Petrol variants consistently fail emissions testing at 77.3 times the fleet average, affecting 1.1, 1.4, and 1.6-litre engines across all mileage bands. The issue stems from deterioration of the catalytic converter, lambda sensor, and carburetor or injection system calibration on older examples. The basic emissions control systems fitted to these engines are prone to component failure and require regular maintenance to meet MOT standards. This is a legal requirement for roadworthiness and affects resale value.
Emissions failures result in immediate MOT failure and legal prohibition from road use until repaired. Typical repairs involve catalytic converter replacement (£200-£400), lambda sensor renewal (£80-£150), or carburetor/injection system adjustment. The vehicle cannot be legally driven on public roads while failing emissions standards.
Check for any engine warning lights on the dashboard. Ask about the car's MOT emissions history — repeated failures suggest underlying issues. A pre-purchase diagnostic scan is especially worthwhile to check for stored emissions fault codes.

Based on 43k real DVSA MOT tests, the Peugeot 106 fails more often than average on several items. The biggest outlier is body panel damage at 165x the fleet average, followed by axle or kingpin wear (129x).
When viewing a specific car, check its MOT history for recurring advisories in these categories. See the full Peugeot 106 MOT failure breakdown for data at every mileage point.
Routine servicing (oil and filter change every 6k miles) typically costs £45–£65 at an independent garage.

The Peugeot 106 has some well-documented weak points, including 4 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. Phase 2 models from 1996 onwards are preferred, bringing improved safety (airbags, side impact bars) and better refinement. Post-1998 (R-reg onwards) cars are favoured by the trade. For GTi buyers, the 16-valve 1.6 produced from 1997 to 2003 is the definitive version.
