Peugeot 206
Most widespread PSA diesel. Went through many evolution stages from Euro 4 to Euro 6. Economical and long-lived with regular servicing. Prone to DPF issues in short-trip operation.
Economical everyday runner
90 hp in the light 206 is more than adequate. Agile and economical, but the infamous turbo failure always lurks in the background.
Engine Weaknesses 6
The 1.6 HDi is notorious for repeated turbocharger failures. Soot particles in the oil alter viscosity, oil lines coke up and the turbocharger runs dry. A second failure after replacement without addressing the root cause is common.
Symptoms: Whistling from the turbocharger, severe power loss, blue or black exhaust smoke, oil leaking from turbo, engine enters limp mode
The copper sealing rings on the injectors wear out, allowing combustion gases and diesel to enter the cylinder head. Oil dilution by diesel can lead to engine damage. Affects all 1.6 HDi variants.
Symptoms: Diesel smell at the dipstick, rising oil level, black deposits around injectors, rough engine running, hissing noises at the cylinder head with engine running
The cam-to-cam timing chain between inlet and exhaust camshafts can stretch or snap. Hydraulic chain tensioners fail, causing valve timing shift and in extreme cases engine damage.
Symptoms: Rattling on cold start, rough engine running, engine management light, power loss, in extreme cases sudden engine shutdown from chain snap
The plastic impeller on the water pump breaks away early and can damage the timing belt or cause engine failure. Engine damage documented from as low as 70,000–88,000 km. Always replace the water pump at the same time as the timing belt.
Symptoms: Engine overheating, timing belt snaps without warning, fan noise, coolant loss
During short-trip use DPF regeneration fails regularly. Deposits in the EGR and throttle body additionally prevent correct regeneration. From 160,000 km complete replacement is frequently needed.
Symptoms: Warning 'particulate filter filling up', noticeable power loss, increased fuel consumption, engine judders under acceleration, limp mode
Leaks around the injector sealing area let exhaust gases into the cylinder head. A gel-like oil residue forms in the head chambers (especially pre-2006 build). Professional cleaning takes around 10 labour hours. Turbo damage threatened by oil contamination.
Symptoms: Turbo damage, power loss, black oil paste around injectors, engine oil contamination
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.
