SensoDrive gearbox, VTS manifold and 1.4 HDi belt on the C2Known weak points

Engine / equipment: Citroën C2 (petrol and HDi)
Period mentioned: 2003–2009
Symptoms: A SensoDrive automated gearbox (1.4 and 1.6 petrol) that will not engage reverse; inlet-manifold bolts that fall out on the 1.6 VTS; whine on the 1.4 HDi from a failing timing-belt tensioner.
Possible cause described: Cases collected by Honest John. On the 1.4 HDi, the belt kit includes the tensioner and the belt-driven water pump should be changed at the same time.
Check for the garage: Test reverse on SensoDrive cars; listen for whine on the HDi; check the manifold bolts on the VTS.

Engines: 1.6 HDi (Diesel)

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.
