What is the 2000-2012 Peugeot 206 Head Gasket Failure?
The TU-series engines in the 206 are prone to head gasket failure, particularly when the cooling system is neglected. Overheating episodes accelerate gasket deterioration, leading to coolant-oil mixing and white exhaust smoke. Repairs typically run $600-$1,200. Severity: high.
What is the 2001-2012 Peugeot 206 BSI (Built-in Systems Interface) Body Control Unit Faults?
The 206's BSI body control computer, which governs central locking, wipers, lights, instrument functions and the immobiliser, is prone to corrupted software, dry solder joints and water ingress — water entering through the bonnet vent and poorly drained plenum chamber can drip on… Repairs typically run $150-$700. Severity: high.
What is the 1998-2012 Peugeot 206 Rear Axle Torsion Beam Trailing Arm Bearing Wear?
The 206's rear torsion-beam axle uses needle roller bearings on the trailing arm shafts that are poorly sealed against the elements; water ingress rusts the bearings away, and the failed rollers then chew up the arm shaft and the inside of the axle tube. The result is the classic… Repairs typically run $450-$1,100. Severity: high.
What is the 2000-2012 Peugeot 206 Power Steering Pump Leak?
The hydraulic power steering pump develops seal leaks over time, causing fluid loss and increasingly heavy steering. The pump housing seals harden with age and mileage exposure. Repairs typically run $200-$500. Severity: medium.
What is the 2001-2012 Peugeot 206 COM2000 Indicator/Wiper Stalk Unit Failure?
The COM2000 steering-column module — which combines the indicator and wiper stalks, horn contact and the multiplex electronics behind them — is a notorious 206 weak point, particularly on multiplexed cars built from July 2001. Worn or grease-fouled contacts cause indicators to se… Repairs typically run $180-$400. Severity: medium.
What is the 1998-2012 Peugeot 206 Ignition Coil Pack Failure (Petrol TU Engines)?
The wasted-spark coil pack on the 206's small petrol engines (1.1 KFV, 1.4 KFW and related TU units) is a frequent failure item: one of the two internal coils breaks down, dropping spark on a paired set of cylinders (1/4 or 2/3). Owners report intermittent misfire, rough running,… Repairs typically run $80-$250. Severity: medium.
What is the 2000-2012 Peugeot 206 'Anti-Pollution Fault' Warning — Emissions System Faults?
A very common 206 complaint on multiplexed cars is the 'Anti-pollution fault' message on the multifunction display, often accompanied by the engine management light, misfire, lost power or limp mode. It is a generic emissions-system alert triggered by a range of root causes docum… Repairs typically run $100-$900. Severity: medium.
What is the 2000-2012 Peugeot 206 Window Regulator Failure?
The electric window regulators on the 206 are a well-known weak point, with the cable-driven mechanism snapping or the motor failing. Front windows are most commonly affected, often dropping into the door. Repairs typically run $100-$300. Severity: low.
What is the 1998-2012 Peugeot 206 Fuel Gauge Sender Unit Failure?
The in-tank fuel level sender on the 206 commonly fails or misreads: the float arm sticks at certain levels, the resistive track wears, or the connector terminals on top of the pump/sender module corrode and lose contact. Owners see the gauge stuck on full or empty, wild fluctuat… Repairs typically run $100-$350. Severity: low.
