Faults:

The only problem the engine had was a turbo failure shortly after 200,000 km, easy to fix although expensive.

When it is very cold, the engine takes a long time to start due to problems with the spark plugs.

The check engine light comes on sporadically. The manual indicates that the engine is overheating in this case. No need to check anything because it will go off after a while. The engine remains running normally.

Suspension spheres must be checked periodically, as poor condition can lead to a loss of stability and reduced ride comfort.

General Comments:

The equipment and comfort are exceptional. The interior is spacious and comfortable, and this version features hydroactive suspension, which improves cornering.

It offers a level of comfort and stability superior to most cars of its time, with excellent road handling, especially in windy conditions.

It's a very good car for traveling long hours; the journey is pleasant, and its easy handling means you won't get tired while driving.

The HDi engine, aside from the minor issues I mentioned, is very robust, reliable and very smooth for a diesel from the early 2000s.

Fuel consumption is incredibly low on the highway, making it ideal for long journeys. It's also comfortable in the city, easy to drive even in heavy traffic, and it doesn't consume too much fuel either, with around 6/100 km in urban driving.

For personal reasons, I had to sell the car after 15 years of use, but I can assure that if I hadn't had such an obstacle, it probably would have still been in my possession today.

It was one of the most comfortable and reliable cars I've ever owned.

General Comments:

My first car was a 1993 bx diesel which I sold with 372000 (!) km on it, the motor was still perfect and needed 5 liter/100km, only for the rest... The biggest cost was everything in regard to the hydraulic suspension, think every part had been replaced in 3 years I had it. Now I bought a 1995 Xantia 19 Diesel with 265000km which has a much higher comfort level. The motor runs very smoothly and hardly makes any noise inside at speeds up to 100Km/h. Once the speed goes up to 120 the motor makes a bit too much noise which probably has to do with the fact that it's not a turbo diesel. It starts like a citroen starts... immediately, just like my BX, but that one had the same engine. Compared to my BX it runs much slower due to the extra weight and uses 1 liter extra diesel/100km, therefore my next one will be a turbo diesel for sure. A big difference is also that the suspension takes smaller bumps or bad road much better then my BX, you hardly notice it. In any way a very good car with an engine that easily can do 400000km, I'm a bit afraid that the suspension is not that maintenance friendly...
