2006 Peugeot 607 problems

• 2.2 HDi 128-138 (DW12 TED4, single turbo, 2000-2006)

  128–138 hp · DW12, DW12TED4

  Fiches-auto documents a recurring DPF clogging problem in this version (98 cases out of 277 reviews); check the maintenance history of the DPF and the additive system before buying.^[2]

  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.^[2][3]

Faults that affect 2006 cars

• High severityFrequency: CommonEmissions controlDPF clogging with additive, especially on the 128-138 hp versionThe particulate filter (DPF) with additive on the 2.2 HDi has a documented recurring problem in the 128-138 hp version (98 cases out of 277 reviews on fiches-auto); the more powerful twin-turbo versions show far fewer cases. The emissions fault warning light comes on and, if ignored, the car loses power.
• 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.

• 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.^[5][6]

Faults that affect 2006 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 16v 158-163 hp (EW12J4, 3FZ/3FY, 1999-2010)

  158–163 hp · 3FZ, 3FY

  Oil consumption is what comes up most in owner reviews of the 2.2 (10 of 56 according to the Fiches-auto.fr table, 5 of them in the 407 2.2, although in the 407 at least one testimony refers to the steering oil rather than the engine). It is a small sample with no independent second source, so it is worth measuring oil consumption and demanding proof of the last timing belt replacement.^{[8][9][10][11][12]}

Faults that affect 2006 cars

• Medium severityFrequency: OccasionalIgnitionFaulty ignition coilsIgnition coils are the fault reported by the press (gebrauchtwagenberater.de, CarsGuide) and by 16 of the 170 owner reviews of the 2.0 EW10; they also appear on the 2.2. A weak coil causes misfires, jerking and the engine warning light coming on.

• High severityFrequency: OccasionalGearbox and clutchWear of the dual-mass flywheel and clutchThe fiches-auto.fr page records 20 owner reports for the 607 about the dual-mass flywheel and 8 about the clutch, with failures between around 42,000 and 280,000 km, some at 120,000 km.
• Medium severityFrequency: CommonElectronics and infotainmentCentral screen and dashboard electronics faultsThe fiches-auto.fr page cites 81 owner reports for the 607 about electronics: the central display that becomes unreadable in the heat, false ESP/ASR/airbag warnings and radio or CD players that lock up.
• Medium severityFrequency: OccasionalElectrical systemStarter motor and alternator failureAccording to the fiches-auto.fr page, 22 owner reports for the 607 talk of a failed starter motor and 19 of the alternator, with failures between around 90,000 and 230,000 km; 13 more mention the battery.
• Low severityFrequency: CommonElectrical systemBreakage of the cable and guides of the electric window mechanismIt is the most cited fault on the fiches-auto.fr page for the 607: 112 of around 365 owner reports talk of broken cables, damaged plastic guides or failing motors, with windows stuck.
