Peugeot 206 MOT Failures

An analysis of 1,614,227 real DVSA MOT tests on the Peugeot 206 — what fails, how often, and how that compares to every other car on UK roads. Generations covered: 206 (1998–2012).

Where the Peugeot 206 fails its MOT

The single biggest MOT failure point on the Peugeot 206 is fuel tank, pipe or hose insecure — this model is 254 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 1,614,227 MOT tests, 0.51% of all Peugeot 206 tests recorded this as a failure.

Bodywork failures usually mean structural corrosion — not cosmetic rust, but rot that affects the car's structural integrity. Check sills, subframes, and chassis rails carefully, especially on older examples.

Other notable weak points include load sensing valve seized or inoperative and ab... (352x the fleet average), load sensing valve linkage defective (257x the fleet average), power steering fault (143x the fleet average), and emissions failure (106x the fleet average). These ratios compare the Peugeot 206'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 6 categories: Bodywork, Brakes, Steering, Exhaust & Emissions, Lights & Electrics and others. If you're inspecting a Peugeot 206 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 206'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 206 specifically, the DVSA data shows the most common failures at this mileage are load sensing valve seized or inoperative and ab... (234x the average) and power steering fault (143x). fuel tank, pipe or hose insecure (138x) and load sensing valve linkage defective (130x) 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 206 specifically, the DVSA data shows the most common failures at this mileage are fuel tank, pipe or hose insecure (94x the average) and load sensing valve seized or inoperative and ab... (93x). load sensing valve linkage defective (64x) and emissions failure (58x) 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 206 specifically, the DVSA data shows the most common failures at this mileage are emissions failure (49x the average) and fuel tank, pipe or hose insecure (47x). axle or kingpin wear (45x) and load sensing valve seized or inoperative and ab... (45x) also appear frequently.

The shift from load sensing valve seized or inoperative and ab... 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 206 specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.

Timing belt failure (interference engine) Dangerous

All petrol 206 engines use interference timing belt designs where piston and valve paths overlap. Affects All; typical independent garage repair cost is £250–£400.

AL4 automatic gearbox failure Major

The AL4 four-speed automatic gearbox is fitted across multiple Peugeot and Citroën models but has fundamental design weaknesses in the valve body and hydraulic control systems. Affects All; typical independent garage repair cost is £800–£1,500.

BSI (Body Systems Interface) module failure Major

The BSI module controls all body electrical systems including central locking, windows, wipers, indicators, and immobiliser. Affects All; typical independent garage repair cost is £200–£500.

Head gasket failure Major

The TU series engines are prone to head gasket failure, particularly the 1.4 8-valve TU3JP engine. Affects All; typical independent garage repair cost is £400–£700.

What to check before buying a Peugeot 206

Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Peugeot 206:

Bodywork — check for fuel tank, pipe or hose insecure, body panel damage. Brakes — check for load sensing valve seized or inoperative and ab..., load sensing valve linkage defective. Steering — check for power steering fault.

Beyond the MOT items, ask specifically about timing belt failure and al4 automatic gearbox failure. These won't show up on a standard MOT but can be expensive to fix — repairs start from £250. 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.
