Citroën SpaceTourer 1

Stronger BlueHDi variant of the 1.6-litre diesel (88 kW) with SCR catalytic converter and AdBlue. Punchy and economical, often paired with the EAT6 automatic. Shares the typical DV6 weak points: turbocharger oil feed line, injector seals and EGR coking. The AdBlue system (NOx sensor, pump, dosing valve) is an additional failure source compared to the predecessor. Timing belt replacement per manufacturer schedule is essential.

• !! AdBlue tank sender faulty — start lockout from 80,000 km

  Identical issue to the BlueHDi 100: the integrated level sensor in the urea tank fails and cannot be replaced individually. Without goodwill or warranty, tank replacement costs up to €1,200. Cold winters accelerate crystallisation problems.

  Symptoms: Warning message 'Check AdBlue', countdown on instrument cluster, start lockout after several cycles

• !! Turbocharger actuator faulty — boost pressure loss from 130,000 km

  The electric turbo actuator on the BlueHDi 120 can fail and lock the turbocharger in one position. This results in permanent boost loss or excessive boost pressure. Repair often requires replacing the complete turbocharger.

  Symptoms: Limp mode, weak acceleration, boost pressure faults P0234/P0299, turbo whistling noise

• !! EGR system: valve and cooler contaminated from 90,000 km

  On the BlueHDi-120, soot builds up intensively in the EGR valve and cooler. Technical reports list EGR damage among the five most common workshop jobs on this engine, alongside injector, FAP and turbo problems. Cleaning every 60,000 km prevents consequential damage.

  Symptoms: Engine warning light, limp mode, increased consumption, hesitation at part load

+ 3 more engine weaknesses + vehicle weaknesses

Top diesel (133 kW) with SCR catalytic converter and AdBlue for Euro 6 compliance. Very punchy with high torque, usually paired with the EAT8 automatic. Ideal for heavy SUVs and long-distance vehicles. Timing belt replacement with water pump should be planned every 160,000 km. Injectors, VGT turbocharger and AdBlue system (NOx sensor, pump) are the main wear items. Oil changes strictly per specification.

• !! AdBlue/SCR system — tank and pump failure from 80,000 km

  BlueHDi engines with SCR urea injection suffer from faulty AdBlue tanks and pumps, especially in winter. The faulty tank unit (pump and sensor integrated) cannot be replaced separately — cost €1,000–2,000. Engine will not start after failure.

  Symptoms: AdBlue warning light, engine warning light, start lockout after countdown warning, fault codes.

• !! Timing belt — interference engine requiring special tooling from 100,000 km

  The BlueHDi DW10F variant is an interference engine. Timing belt replacement requires specific PSA special tools (NTN-SNR kit). Incorrect installation leads to engine damage. Interval: 5 years or 100,000 km.

  Symptoms: Sudden engine stall, metallic noises, no restart on snap.

• !! DPF — regeneration failure and oil dilution from 100,000 km

  BlueHDi DPF regenerates actively via post-injection. With insufficient running time, unburnt fuel passes into the engine oil (oil dilution). Regular oil level checks and motorway drives for regeneration are mandatory.

  Symptoms: DPF warning light, oil level rising, engine warning light, strong diesel smell in oil.

+ 3 more engine weaknesses + vehicle weaknesses

Stronger 150 hp variant (110 kW) of the 2.0 HDi or BlueHDi. Punchy and strong on torque, ideal for heavier vehicles and long-distance driving. From 2014 onwards available as BlueHDi with SCR catalytic converter and AdBlue. Timing belt replacement with water pump should be planned every 160,000 km. Injectors and turbocharger are the main wear items. AdBlue system is an additional failure source on BlueHDi versions.

• !! Timing belt — interference engine from 100,000 km

  Interference engine: timing belt snap leads to piston-to-valve collision. Manufacturer recommends 80,000–120,000 km or 5 years. Used C5 II vehicles frequently lack complete service records. Having the kit on hand saves time at the workshop.

  Symptoms: Sudden engine stall, no restart, metallic rumbling.

• !! DPF/FAP — clogging from short-trip use from 120,000 km

  PSA FAP system with Eolys additive: the particulate filter only regenerates at sufficient temperature (motorway driving). Short-trip use prevents complete regeneration and the filter clogs. Failed regeneration attempts increase oil dilution.

  Symptoms: FAP warning light, power reduction, increased fuel consumption, limp mode.

• !! Turbocharger — bearing damage from carbon from 130,000 km

  The VNT turbo suffers from carbon build-up from the EGR system. Vanes lock up, bearings wear from insufficient oil supply with extended change intervals. Repair costs €500–1,500.

  Symptoms: Whistling noise under acceleration, power loss, blue exhaust, oil in the intake hose.
