Top issues to watch for
The most serious Peugeot 306 problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.
Dangerous
Brake hose deterioration and failure (306)
Flexible brake hoses on the 306 deteriorate at an exceptional rate compared to other vehicles of this era. The MOT data shows failure rates over 130 times the national fleet average on some variants. The rubber compounds used appear prone to cracking, chafing and internal breakdown, which can cause sudden brake fluid loss or restricted brake pressure. This affects all engine variants and becomes critical on higher mileage examples where hoses may be original.
What happens if ignoredA failed brake hose causes immediate and total brake failure on the affected circuit. On older brake systems this can mean loss of front or rear braking entirely. Complete brake hose replacement costs £200-400 but is essential safety work. The car is unsafe to drive with deteriorated brake hoses.

Steering rack gaiter and ball joint dust cover failure (306)
The rubber gaiters protecting the steering rack and ball joints fail at over 40 times the fleet average according to MOT data. Once these protective boots are torn or missing, dirt and moisture contaminate the steering components causing rapid wear of ball joints and steering rack internals. This is particularly problematic on the 306 due to the design and rubber compound used.
What happens if ignoredFailed gaiters allow rapid contamination and wear of steering components. Ball joint wear creates dangerous steering looseness and potential wheel detachment. Steering rack contamination causes progressive steering stiffness and eventual rack replacement. Individual ball joint replacement costs £80-150 per side, rack replacement £400-800.

Emissions system deterioration - petrol variants (306)
Petrol variants show emissions failures at up to This exceptionally high rate suggests systematic problems with the catalytic converter, lambda sensors, or engine management system on these engines. The 306 petrol engines use early emissions control technology that deteriorates more rapidly than modern equivalents.
What happens if ignoredEmissions failures result in automatic MOT failure and legal prohibition from driving on public roads. Catalytic converter replacement costs £300-800 depending on variant. Lambda sensor replacement costs £150-300. Multiple components may need replacement simultaneously, and diagnosis requires specialist equipment.

Brake caliper seizure (306)
MOT data shows brake imbalance failures at over 25 times the fleet average, indicating widespread brake caliper seizure problems. The 306 uses single-piston sliding calipers that are prone to corrosion of the slider pins and piston seals, causing uneven braking forces between wheels on the same axle. This creates dangerous braking imbalance and premature pad wear.
What happens if ignoredSeized calipers cause dangerous braking imbalance, automatic MOT failure, and accelerated brake component wear. The affected brake may not release properly causing constant drag, overheating, and potential brake fire. Caliper overhaul costs £80-150 per side, replacement £120-200 per side including labour.
