3 known faults with sources

Turbo oil starvation from injector carbonTurbo / injection

Engine / equipment: 1.6 HDi DV6 (Peugeot 207/308/3008/Partner, Citroën C3/C4/Berlingo; same engine as the Ford 1.6 TDCi)
Period mentioned: Approx. 2004–2015
Symptoms: Loud turbo whistle, power loss, blue or black smoke, oil that gets dirty very quickly. Before the failure, often a puffing or ticking from the cylinder head and an exhaust smell from an injector.
Possible cause described: The injector clamp bolts work loose, the gas leak forms carbon that gets into the oil and clogs the mesh filter in the banjo bolt feeding the turbo. The turbo is starved of oil. Replacing only the turbo does not fix it.
Check for the garage: Check injector bolt torque and carbon at their base, the turbo banjo bolt and the sump strainer.
Cost cited in the source: Turbo + full oil system cleaning: approx. €900–2,000 (estimate)A rough figure from the original database, not an up-to-date quote.

Applies if: Only if fitted with the automatic gearbox described in the record.

EAT6/EAT8 jerking and torque converterAutomatic gearbox

Engine / equipment: Aisin EAT6 and EAT8 automatic gearboxes (308, 3008, 5008, 508, 2008, C4 Picasso, C5 Aircross, C4, DS 7, Grandland…)
Period mentioned: 2013–2026
Symptoms: Hesitation or a jolt between 1st and 2nd, torque converter shudder in traffic, harsh or delayed shifts and a gearbox fault warning, especially on 2017–2019 3008s.
Possible cause described: Torque converter wear or drift, valve deposits from degraded oil and software faults. Peugeot treats the oil as lifetime, but dirty or low oil causes harsh shifts.
Check for the garage: Check oil level and condition, update the gearbox software at the dealer and, after an oil change, record it with DiagBox and reset the adaptations.
Cost cited in the source: Oil change and update: the most common fix; torque converter or valve body: specialist garage repairA rough figure from the original database, not an up-to-date quote.

Applies if: Only cars built up to 20/6/2016.

Rear cross-member squeak on the Peugeot 308 IISuspension and steering

Engine / equipment: Peugeot 308 II built up to June 2016
Period mentioned: 2013–2016
Symptoms: Squeak from the rear axle on uneven roads or when the car's weight shifts in bends; it gets worse with mileage. A knock from the rear can also come from the silencer's rubber mount (cars built up to 9/10/2016).
Possible cause described: Rubbing between the pressed lower part and the rounded upper part of the rear cross-member. It affects cars built up to 10/12/2015 with a 25,000 Nm/rad anti-roll bar (the cross-member is replaced) and, according to a January 2017 note, those with a 30,000 Nm/rad bar built up to 20/6/2016 (some parts are replaced).
Check for the garage: Tell the garage when it squeaks (bumps, bends) and ask about the technical note on the cross-member; also have the silencer's rubber mount checked.
Cost cited in the source: No verified estimate; ask the garage for a quote.A rough figure from the original database, not an up-to-date quote.
