Citroën Xsara
Entry-level variant of the proven 2.0 HDi. Low consumption but very low on power. Mainly found in light commercial vehicles and vans.
Two-litre with 90 hp
90 hp from 2.0 litres — lots of displacement, little power; robust and long-lived in compensation.
Engine Weaknesses 6
Interference engine: if the timing belt snaps, valves strike pistons. PSA interval 80,000–120,000 km or 5 years. Many used vehicles have no documented history. Repair costs after snap: €2,000–6,000.
Symptoms: Engine suddenly won't start, metallic impact, engine oil with metal swarf.
Bosch injectors wear internally and develop excessive fuel return flow. Rail pressure drop leads to starting difficulties. Low-quality diesel significantly accelerates precision nozzle erosion.
Symptoms: Rough idle, starting difficulties, increased fuel consumption, black smoke.
Turbo bearings can fail from oil starvation or sludge. Early DW10 variants suffered from clogged oil galleries containing casting sand residue from cylinder head manufacturing. Incorrect oil spec accelerates failure.
Symptoms: Power loss, blue/white exhaust, whistling noises from the turbo.
The mechanically driven vacuum pump on the DW10-90 wears or loses sealing. The brake servo no longer receives sufficient vacuum. Braking force is severely reduced, brake pedal feels hard. Safety risk.
Symptoms: Hard brake pedal requiring significantly more effort, poor braking deceleration, whistling noise when braking. Brake pedal gives slightly after prolonged pressure.
The EGR valve clogs with soot from recirculated exhaust gases, especially with short-trip use. A sticky valve causes power loss, elevated emissions and engine warning light.
Symptoms: Hesitation under acceleration, engine warning light, increased fuel consumption, power loss.
The copper sealing washers on the DW10 common rail injectors wear and allow combustion gases to blow by the injector. High-pressure line connections become loose. Black deposits visible around the injectors.
Symptoms: Ticking noise at idle (combustion gases escaping), visible black deposits around injectors, slight burnt oil smell, unstable idle.
Vehicle Weaknesses 5
On the Xsara the electric thermal switch for the radiator, which should activate the cooling fan when water temperature rises, frequently fails. Without timely fan operation the engine risks overheating.
The Xsara's braking system receives poor marks at MOT inspections: wear and insufficient braking performance are frequently flagged. Handbrake and footbrake performance in particular stand out.
Oil loss at the engine block is a classic Citroën problem that was not resolved in the Xsara. Typical is oil seepage upper right on the engine block from a leaking head gasket — should be checked before purchase.
At 12.8% of all Xsara vehicles presented at the MOT, lighting defects are flagged — the single most common fault. Blown bulbs, corroded sockets, and failed headlight adjusters are typical causes.
The air conditioning on older Xsara models regularly loses refrigerant through aged seals. On vehicles over 10 years old annual top-ups are often necessary. Air conditioning compressors can also cause problems.
