Reliable

Reliability, common problems and owner reviews for the Peugeot 206 1.1 / 1.4 / 1.6 (TU petrol). Check this before you buy used.

The naturally-aspirated TU petrols (1.1/1.4 8v and the sweeter 1.6 16v NFU) are the simple, dependable heart of the 206 — belt-driven, port-injected, mechanically uncomplicated and very cheap to keep going, which is why so many survive. Cautions are minor and age-related: timing belt on schedule, the odd coil/lambda/ignition niggle, and rust around the car more than the engine. The 1.6 16v is the pick for a bit more life. An honest, low-cost runabout engine with decades of proven parts availability.

Same engine, other cars

This is the same physical engine (EP3) sold under different names across brands. Reliability is broadly shared — cross-check these:

Known Issues

Timing belt servicerecurring

Belt-driven; change on schedule (interference engine).

Fix / Workaround: Belt + tensioner per schedule.

Repair cost: €200–€400

Typically appears after: 100,000 km

Coils / lambda / age nigglesminor

Ignition, lambda and sensor items with age.

Fix / Workaround: Replace as needed; cheap parts.

Repair cost: €40–€250

Typically appears after: 120,000 km

Cylinder head gasket weep (TU3 1.4 especially)recurring

The old TU units, especially the 1.4 8v, are known for external head gasket weeps at the front corner — oil/coolant traces, rarely catastrophic but a bargaining point and eventually a repair.

Fix / Workaround: Look at the head-block joint under the exhaust manifold; a weep can be lived with if levels are watched, or fixed properly with a gasket.

Repair cost: €250–€500

Typically appears after: 150,000 km

Coil rail and ignition faultsminor

The one-piece coil rail fails with age causing multi-cylinder misfires — a very common and cheap TU fix.

Fix / Workaround: Replace the coil rail and plugs together.

Repair cost: €50–€130

Mileage Thresholds

After 220,000 km: Very durable, cheap to run.

After 200,000 km: Head gasket weep check and belt history are the whole story — the bottom end is effectively unkillable with oil in it.

Fault Codes to Scan

P0420Catalyst efficiency below threshold — cats age on these; check for oil use too.minor

Pre-Purchase Checklist
