Top issues to watch for

The most serious Citroen Xsara problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.

Major
Diesel particulate filter blockage and emissions failures
Phase2, Phase32000–201040k–150k miles
HDi diesel engines from 2003 onwards are fitted with a diesel particulate filter (DPF) that captures soot particles during normal driving. The system requires regular high-temperature regeneration cycles to burn off accumulated soot, typically achieved during motorway driving. Urban driving patterns prevent proper regeneration, causing the DPF to become blocked with carbonised deposits. This leads to dramatic increases in exhaust smoke opacity, power loss, and eventually prevents the car from passing the MOT emissions test.
What happens if ignoredA completely blocked DPF requires professional forced regeneration (£150-250) or replacement (£800-1500 plus fitting). The car will fail the MOT emissions test and may enter limp mode with severely restricted performance. Continued driving with a blocked DPF can damage the turbocharger due to excessive back pressure.

Major
Power steering pump failure and hydraulic leaks
Phase1, Phase2, Phase31997–201020k–150k miles
The Xsara uses a belt-driven hydraulic power steering system with a high-pressure pump mounted on the engine. The pump develops internal seal failures that cause power steering fluid leaks and eventual complete loss of assistance. This is a well-documented weakness across all Xsara variants, with MOT data showing failure rates 133 times higher than the fleet average. The system uses LHM mineral hydraulic fluid which is corrosive to rubber seals over time.
What happens if ignoredComplete pump failure results in very heavy steering, making the car difficult to manoeuvre at low speeds and potentially dangerous in emergency situations. Replacement pumps cost £200-400, with 2-3 hours labour for fitting. Continued driving with low fluid levels will damage the steering rack, increasing repair costs significantly.

Major
Brake flexible hose deterioration
Phase1, Phase2, Phase31997–201080k–150k miles
The brake system uses flexible rubber hoses to connect the rigid brake lines to the brake calipers at each wheel. These hoses are subject to heat cycling from the brakes and exposure to road salt, causing the rubber to perish and crack over time. MOT data shows the Xsara fails at 282.9 times the fleet average for brake hose deterioration. Failed hoses can cause brake fluid leaks, loss of braking efficiency, or complete brake failure in extreme cases.
What happens if ignoredDeteriorated brake hoses represent a serious safety risk and will cause immediate MOT failure. In extreme cases, complete hose failure can result in total loss of braking at one or more wheels. Replacement involves fitting new hoses and bleeding the brake system, typically costing £150-300 depending on how many hoses need replacement.

Major
ABS system component failure
Phase1, Phase2, Phase31997–201060k–150k miles
The Xsara ABS system uses wheel speed sensors and an ABS pump/modulator unit to prevent wheel lockup during emergency braking. The wheel speed sensors are prone to failure due to corrosion of the sensor wiring and contamination of the sensor rings. The ABS pump can also develop internal faults, particularly on higher mileage examples.
What happens if ignoredABS failure means the car will not pass the MOT test and emergency braking performance is compromised, particularly on wet or slippery surfaces. Wheel speed sensor replacement typically costs £100-200 per sensor. ABS pump failure is more expensive, often requiring a replacement unit costing £300-800 plus labour and system bleeding.
