Top issues to watch for

The most serious Peugeot 307 problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.

Dangerous
Brake hose deterioration
T5, T5FL2001–200820k–150k miles
The 307 exhibits exceptionally high brake hose failure rates, with MOT data showing failures up to 110 times the national fleet average. The flexible brake hoses connecting the brake lines to the calipers are prone to deterioration, cracking, and bulging under pressure. This affects the structural integrity of the brake system and represents a serious safety risk.
What happens if ignoredBrake hose failure can cause sudden total loss of braking ability, creating an extreme safety hazard. Even minor deterioration affects brake performance and will cause MOT failure. Complete brake system inspection and hose replacement typically costs £200-400. A catastrophic hose failure while driving could result in a serious accident. The vehicle should not be driven if brake hose integrity is in doubt.

Major
Excessive diesel smoke emissions (HDi)
T5, T5FL2001–200840k–150k miles
The 307 diesel variants suffer from significantly higher smoke opacity levels than the national fleet average, with MOT data showing failure rates up to 140 times higher than typical cars. This indicates problems with the diesel particulate filter system, EGR valve carbon build-up, or injection system wear. The issue affects all diesel engine variants and becomes more prevalent with higher mileage as carbon deposits accumulate.
What happens if ignoredFailed MOT test is likely if smoke levels are excessive. DPF regeneration or cleaning typically costs £200-400, but a blocked DPF requiring replacement can cost £800-1500. Continued driving with a blocked DPF can damage the turbocharger and engine. The car remains driveable but will fail its annual test.

Major
Premature steering ball joint wear
T5, T5FL2001–200820k–150k miles
The 307 shows exceptionally high failure rates for steering ball joints, with MOT data indicating failures up to 111 times the national average. This affects the track rod ends which connect the steering rack to the front wheels. The design appears prone to premature wear of the ball joint seals and internal components, leading to excessive play that creates safety concerns and MOT failure.
What happens if ignoredWorn ball joints create dangerous steering unpredictability and will cause MOT failure. If a ball joint separates completely, the wheel can fold inward causing total loss of steering control and potential accident. Replacement of both track rod ends typically costs £150-300 plus wheel alignment. The car should not be driven with severely worn ball joints.

Minor
Suspension component bush wear
T5, T5FL2001–200820k–150k miles
MOT data shows the 307 suffers from suspension bush and joint wear at rates up to 60 times the national average. This typically affects the front suspension drop links, rear beam bushes, and subframe mounting points. The rubber components deteriorate prematurely, causing knocking noises, poor handling, and uneven tire wear.
What happens if ignoredWorn suspension bushes cause poor handling, increased tire wear, and knocking noises. The car remains safe to drive but handling deteriorates and MOT failure is likely. Replacement of drop links typically costs £80-150, while rear beam bushes can cost £200-400. Multiple worn components can result in repair bills of £300-600.
