Peugeot 206
Powerful PSA diesel for mid-size and SUV applications. Common rail with turbo. Later versions as BlueHDi with SCR cat and AdBlue.
Big engine, small car
2.0 HDi with 90 hp in the 206: an unusual combination with lots of torque at low revs. Robust but heavy-footed.
Engine Weaknesses 7
The plastic impeller of the water pump can disintegrate from as early as 50,000 km. Fragments enter the timing belt drive and cause the belt to snap with subsequent total engine destruction.
Symptoms: Coolant temperature rises unusually, coolant loss without visible leak, faint grinding or squealing from the timing belt drive, sudden engine shutdown when belt snaps
The dual-mass flywheel wears prematurely, especially on the 107 hp variant. Oil dilution from DPF regeneration accelerates wear. The clutch should always be renewed at the same time.
Symptoms: Squealing or clattering when starting and stopping the engine, pronounced vibrations at idle, juddering when pulling away, knocking at low revs under load
Leaking injectors allow diesel into the engine oil, drastically reducing its lubricity. The rising oil level is often overlooked. This can cause piston and bearing damage.
Symptoms: Diesel smell at the dipstick, oil level rises above maximum, strong exhaust smell inside the car, engine judders or knocks more than usual, increased fuel consumption
After switching off a hot engine the oil lines to the turbocharger can coke up. On the next start the turbocharger briefly runs without lubrication. Mainly affects the more powerful DW10 variants.
Symptoms: Increasing whistling or whining from the turbocharger, oil spots under the car in the turbo area, gradual power loss, blue smoke after the engine has been standing
Internal EGR cooler failure routes coolant into the exhaust gases. Coolant disappears without visible external leak. Repair requires 13.2 hours of labour. Cost 800–2,000 €.
Symptoms: Coolant drops without visible leak, white smoke from exhaust, heater won't warm up
The PSA-proprietary additive (Eolys) is mixed into the fuel and enables regeneration at a lower temperature. A defective additive pump or empty reservoir prevents regeneration and clogs the FAP prematurely. Change interval 120,000–180,000 km.
Symptoms: Warning 'particulate filter will soon clog', increased fuel consumption, power loss, regeneration attempts visible as idle speed fluctuations
The EGR valve seizes with soot deposits or no longer closes fully. The result is warning messages, poor cold-start behaviour and increased particulate output into the filter, causing it to clog faster.
Symptoms: Warning 'exhaust aftertreatment system fault', poor cold-start behaviour, light smoke when accelerating, occasional judder under load
Vehicle Weaknesses 10
Sills and wheel arches rust through on older 206s. Vehicles built before 2002 are particularly affected. Rotten sills fail the MOT/TÜV and require extensive welding repairs.
The water pump on the petrol engines in the 206 starts leaking at 80,000–120,000 km, causing a slow coolant loss. Ignoring it risks overheating with consequential cylinder head damage. Regular coolant level checks are recommended.
The needle roller bearings in the torsion beam rear axle typically wear between 100,000 and 150,000 km. Moisture and dirt get in through failed seals and destroy the bearings. The right side is usually first.
Wishbone bushes on the front axle wear out on early build years (to 2002) sometimes after just 20,000 km. Later models last longer, but control arms are among the most common TÜV/MOT failures on the 206.
The manual gearbox tends to be stiff to shift and jump out of gear. Worn synchro rings and failed clutches are the most common causes. In severe cases the gearbox can fail completely.
The A/C compressor on the 206 loses cooling performance after 60,000–100,000 km through refrigerant loss or internal wear. Cars without regular A/C servicing are affected earlier.
The exhaust system on the 206 is particularly rust-prone. Rear silencer and flex pipes can rust through after just a few years. Short-trip use makes matters worse as condensed water accelerates internal corrosion.
Failed headlights, central locking failures and instrument cluster malfunctions are frequent. ADAC reports particularly on 1999 model years with persistent ECU fault codes and immobiliser problems.
The front brakes lack a dust shield, which was omitted for cost and cooling reasons. This allows more dirt and moisture to accumulate, leading to increased wear and corrosion on the brake discs.
Electric window regulators fail frequently, particularly at the front doors. Failed motors or worn cables are usually the cause. The problem is more common on vehicles built before 2001.
