Top issues to watch for

The most serious Peugeot 205 problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.

Dangerous
Structural corrosion compromising vehicle rigidity
2051983–199860k–200k miles
The 205 uses a galvanized body shell but critical structural areas including sills, rear beam mounting points, and suspension mounting areas were not fully protected. Over 30+ years, these areas corrode to the point where structural integrity is compromised. MOT data shows this model fails structural rigidity tests at 17.1x the fleet average. This is particularly severe on cars that have not been stored in dry conditions or have been exposed to road salt over many winters.
What happens if ignoredIf load-bearing structures fail, the car becomes unsafe to drive and may not protect occupants in an accident. MOT failure is mandatory for structural defects. Repair typically requires cutting out corroded sections and welding in new metal - often exceeding the car's value.

Dangerous
Brake pipe corrosion and flexible hose deterioration
2051983–199840k–200k miles
The brake system uses steel pipes and rubber flexible hoses that deteriorate over the 30+ year age of these vehicles. MOT data shows brake pipe corrosion failures at 16.6x the fleet average and flexible hose failures at 57.2x the fleet average. The flexible hoses connecting the calipers to the solid pipes are particularly vulnerable to cracking from age and exposure to road debris and brake fluid contamination.
What happens if ignoredBrake system failure creates immediate danger to occupants and other road users. Complete brake failure can occur without warning if pipes or hoses rupture. The car should not be driven if brake system integrity is compromised.

Major
CV joint boot deterioration and joint wear
2051983–199840k–150k miles
The driveshaft constant velocity joints are protected by rubber boots that prevent dirt and water ingress while retaining lubricating grease. These rubber boots deteriorate over time and mileage, allowing contamination to enter the joint. MOT data shows CV joint boot failures at 20.6x the fleet average. Once the boot splits, the joint rapidly wears and will eventually fail completely, leaving the car immobile.
What happens if ignoredSplit boots allow rapid CV joint wear. If the joint fails completely, the driveshaft separates and the car loses drive to that wheel. Early boot replacement is much cheaper than joint replacement once wear has occurred.

Major
Emissions system deterioration (petrol variants)
2051124cc, 1360cc, 1580cc1983–1998100k–200k miles
The petrol engines in the 205 use basic emissions control systems that deteriorate with age and high mileage. 6 and 1.9 litre variants at higher mileages. The catalytic converter, lambda sensor, and engine management components all contribute to emissions control and can fail independently.
What happens if ignoredEmissions failures result in automatic MOT failure and the car cannot be legally driven on public roads. Repair may require catalytic converter replacement, lambda sensor renewal, or engine management system work depending on the root cause.
