2007 Citroën C6 problems
The 2007 Citroën C6 was sold with 2 engines that we have documented: the TDV6 / SDV6 and the 2.2 HDi. All of them have serious faults that affect the cars of that year. The safest option is the 2.2 HDi (verdict “With caution”). Outside the engine, 4 documented faults affect 2007 cars, such as jerking and hydraulic block faults in the Citroën C6 six-speed automatic gearbox.

What changes compared with the 2006 Citroën C6
The same engines and the same documented faults as in 2006.
TDV6 / SDV6 engine in the 2007 Citroën C6
Names: 2.7 HDi V6
- With caution
2.7 TDV6 (276DT/DT17, 2004-2010)
190–200 hp · 276DT, DT17
You need to verify that the belt and oil pump have been replaced with the improved part.[2][3]
Faults that affect 2007 cars
- Critical severityFrequency: OccasionalLubricationCrankshaft breakage and spinning main bearing shellsOn the TDV6/SDV6 in the Discovery 3 and 4, Range Rover and Range Rover Sport, crankshaft failures have been documented caused by main bearing shells that are badly seated or that spin; the engine can seize and needs replacing or rebuilding.
- Critical severityFrequency: OccasionalTimingBroken oil pump housing and timing belt jumping on the 2.7On the 2.7 TDV6 the belt tensioner is bolted to the oil pump housing; if that part gives way, the belt jumps and the engine, an interference design, can be destroyed. Specialists fit the improved pump along with the belt.
2.2 HDi engine in the 2007 Citroën C6
Names: 2.2 HDi 173
- With caution
2.2 HDi 170-175 twin-turbo (DW12 BTED4, 2005-2010)
170–175 hp · DW12, DW12BTED4, ZSD-422
The two-turbo system adds mechanical complexity; fiches-auto records a significant number of turbo cases in the twin-turbo versions, although, according to the same source, it does not amount to a chronic problem.[5][6]
Faults that affect 2007 cars
- High severityFrequency: OccasionalTurboTurbo faults, somewhat more frequent on the sequential twin-turbo versionsThe 2.2 HDi comes in single-turbo versions (128-156 hp) and twin-turbo versions with two turbochargers in sequence (170 hp and up). Fiches-auto does not consider it a chronic problem, but it does record a significant number of turbo cases across all power outputs, somewhat higher on the twin-turbos.
- High severityFrequency: OccasionalInjectionPiezo injector wear and failureThe 2.2 HDi uses third-generation common-rail injection with piezo injectors at up to 1,800-2,000 bar. Fiches-auto documents injector cases across several power outputs, without it being the most repeated fault, with symptoms of hard starting, jerking or higher fuel consumption.
- Medium severityFrequency: RareClutchDual-mass flywheel wear, less frequent than on other HDi enginesThe 2.2 HDi has a dual-mass flywheel but, unlike smaller HDi engines such as the 1.6 HDi, fiches-auto does not document a chronic problem: very few cases in the tables consulted. Even so, it is a wear part: vibration and knocking are the signs to watch for before buying.
Faults outside the engine in the 2007 Citroën C6
- High severityFrequency: OccasionalGearbox and clutchJerking and hydraulic block faults in the Citroën C6 six-speed automatic gearboxAccording to fiches-auto.fr, 23 of 151 C6 owner reports cite six-speed automatic gearbox faults: jerking, hesitation when changing gear and locking in P; one case puts the hydraulic block at around €2,200.
- Medium severityFrequency: OccasionalSuspensionHydractive suspension faults on the Citroën C6: leaks, height sensors and spheresAccording to the fiches-auto.fr owner reports, 16 of 151 C6 owners cite Hydractive suspension problems: leaks, faulty height sensors, incorrect ride height and excessive firmness; repairs of around €350 to €1,090 depending on the case.
- Medium severityFrequency: OccasionalElectrical systemAlternator failure and battery problems on the Citroën C6According to fiches-auto.fr, 12 of 151 C6 owner reports cite alternator failures, with repairs of around €600 to €800, and another 6 talk about battery problems.
- Low severityFrequency: RareBrakesABS sensor failure on the Citroën C6According to fiches-auto.fr, 9 of 151 C6 owner reports cite ABS sensor failures, with repairs of around €400 per case.
