Peugeot 205 MOT Failures
An analysis of 33,186 real DVSA MOT tests on the Peugeot 205 — what fails, how often, and how that compares to every other car on UK roads. Generations covered: 205 (1983–1998).
Where the Peugeot 205 fails its MOT
The single biggest MOT failure point on the Peugeot 205 is emissions failure — this model is 295 times more likely to fail on this item than the average car on UK roads. That makes it an extreme outlier for anyone buying or owning this model. Across 33,186 MOT tests, 6.97% of all Peugeot 205 tests recorded this as a failure.
Exhaust and emissions failures often point to catalytic converter degradation, lambda sensor faults, or — in diesel models — DPF problems. These can be expensive to fix and will cause an immediate MOT failure.
Other notable weak points include service brake efficiency below minimum requirement (98x the fleet average), electrical wiring fault (18x the fleet average), braking effort inadequate at a wheel (72x the fleet average), and headlight fault (20x the fleet average). These ratios compare the Peugeot 205's failure rate on each item against the national average for all cars tested — a ratio of 10x means this model fails ten times more often than a typical car.
The failures span 4 categories: Exhaust & Emissions, Brakes, Lights & Electrics, Suspension. If you're inspecting a Peugeot 205 before purchase, these are the areas to focus on — and if any have been flagged as advisories on a previous MOT, they're likely to become failures in the near future.
How failures change with mileage
The Peugeot 205's weak points shift as the car covers more miles. Understanding these patterns helps you know what to expect — and what to budget for — at each stage of ownership.
Under 60,000 miles
At this mileage, most failures are either design-related or caused by age rather than wear. Components like bushes and drop links may not have been replaced yet, and original-fit parts can deteriorate even on low-mileage cars that spend a lot of time sitting.
For the Peugeot 205 specifically, the DVSA data shows the most common failures at this mileage are brake hoses perished or damaged (118x the average) and service brake efficiency below minimum requirement (98x). wheel bearings worn (77x) and anti-roll bar links worn (37x) also appear frequently.
60,000 to 100,000 miles
This is where routine wear items start to show up. Brake components, tyres, and exhaust parts have done serious work by this point. Cars that have been well serviced will show fewer of these failures — this mileage band is where good maintenance really separates the well-kept from the neglected.
For the Peugeot 205 specifically, the DVSA data shows the most common failures at this mileage are emissions failure (295x the average) and light unit fault (146x). braking effort inadequate at a wheel (72x) and cable damaged or knotted (49x) also appear frequently.
Over 100,000 miles
High-mileage cars accumulate failures across multiple systems. The key question isn't whether things will need doing — they will — but whether the car has been maintained well enough to keep on top of them. Look for a consistent service history and recent MOT passes with minimal advisories.
For the Peugeot 205 specifically, the DVSA data shows the most common failures at this mileage are emissions failure (172x the average) and brake on any wheel grabbing severely (35x). body panel damage (34x) and braking effort inadequate at a wheel (29x) also appear frequently.
The shift from brake hoses perished or damaged at lower mileages to emissions failure at higher mileages is typical — early failures tend to be design or factory-related, while high-mileage failures reflect accumulated mechanical wear. A car that's been well maintained will usually dodge the worst of both.
Known issues beyond the MOT
An MOT only tests roadworthiness at a single point in time — it won't catch developing faults, intermittent problems, or issues that haven't yet reached the failure threshold. These are the issues that Peugeot 205 specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
Structural corrosion compromising vehicle rigidity Dangerous
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. Affects 205; typical independent garage repair cost is £500–£2,000.
Brake pipe corrosion and flexible hose deterioration Dangerous
The brake system uses steel pipes and rubber flexible hoses that deteriorate over the 30+ year age of these vehicles. Affects 205; typical independent garage repair cost is £150–£400.
CV joint boot deterioration and joint wear Major
The driveshaft constant velocity joints are protected by rubber boots that prevent dirt and water ingress while retaining lubricating grease. Affects 205; typical independent garage repair cost is £80–£150.
Emissions system deterioration (petrol variants) Major
The petrol engines in the 205 use basic emissions control systems that deteriorate with age and high mileage. Affects 205; typical independent garage repair cost is £200–£600.

What to check before buying a Peugeot 205
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Peugeot 205:
Exhaust & Emissions — check for emissions failure. Brakes — check for service brake efficiency below minimum requirement, braking effort inadequate at a wheel, brake hoses perished or damaged. Lights & Electrics — check for electrical wiring fault, headlight fault, light unit fault.
Beyond the MOT items, ask specifically about structural corrosion compromising vehicle rigidity and brake pipe corrosion and flexible hose deterioration. These won't show up on a standard MOT but can be expensive to fix — repairs start from £500. A specialist pre-purchase inspection is worth the investment on this model.
Always check the car's full MOT history for patterns — recurring advisories often become failures within 12 months. And verify the service history to confirm maintenance has been kept up to schedule. Enter any reg into our free car check to see the complete picture.

Peugeot 205 MOT FAQs
What are the most common MOT failures on a Peugeot 205?
Based on 33,186 DVSA MOT tests, the most common failure is emissions failure — at 295x the national fleet average. Other frequent failures include service brake efficiency below minimum requirement and electrical wiring fault.
Is the Peugeot 205 reliable based on MOT data?
The Peugeot 205 has 23 MOT failure categories above the fleet average. Specialists also flag structural corrosion compromising vehicle rigidity as a concern. A pre-purchase inspection and service history check are recommended.
What MOT failures should I expect at high mileage?
Above 100,000 miles, the Peugeot 205 most commonly fails on emissions failure and brake on any wheel grabbing severely. Under 60,000 miles, the main issues are brake hoses perished or damaged and service brake efficiency below minimum requirement.
