PSA/Ford 1.6 HDi, e-HDi, TDCi and BlueHDi (DV6)Urgency: Garage soon

Noise when accelerating in the 1.6 HDi engine: causes

In the 1.6 HDi engine, 1 documented fault may be the cause: turbo failure through lack of lubrication (carbon deposits and union filter).[1]

What to do now

Garage soon

Note when it happens (engine cold or warm, at what speed, in a straight line or turning) and do not ignore it: ask for an inspection at a garage before the noise gets worse.

What it means

A noise that appears or changes when you press the accelerator can come from the exhaust, the dual-mass flywheel, the engine mounts, the driveshafts or the turbo. The type of sound (whistle, roar, rattle, metallic knock) and when it appears point towards the cause, but do not confirm it.

Most serious fault among the possible causes: High severity

Other common causes: noise when accelerating

Besides the documented faults of the 1.6 HDi, these are the most common causes on any car according to the sources.

What to check first

  1. Pay attention to how it sounds (whistle, roar that changes pitch, rattle, metallic knock, shudder) and when it appears: with the engine cold or warm, at idle, when accelerating hard, above a certain speed or with the steering on full lock. Autodoc Club recommends not ignoring these noises and having the car checked.[9][10][16]
  2. With the car idling, press the clutch pedal: according to Diariomotor, if the vibrations reduce or disappear, the dual-mass flywheel is worn. RACE warns that the symptoms alone do not confirm it, because they can also come from the clutch, the engine or gearbox mounts, the injection or the ignition.[12][14]
  3. Have the exhaust inspected over a pit or on a lift: firm mountings, damp patches on the silencer and, if the floor of the cabin gets hot, burnt heat shields.[10]
  4. Look around the wheels: grease thrown outwards indicates that a CV joint boot has split.[16]
