Ford Fiesta (VI) 1.4 / 1.5 / 1.6 TDCi common problems.

Engine / equipment

1.6 TDCi (DV6)

Period mentioned

Approx. 2004–2018

Symptoms

Hissing from the engine, diesel smell in the cabin, very dark oil between changes and, eventually, a failing turbo with smoke and loss of power.

Possible cause described

The injectors’ copper washers stop sealing; the gases form carbon that gets into the oil and blocks the mesh filter in the turbo oil-feed pipe, starving the turbo. The wrong oil and switching off with the turbo very hot make it worse.

Check for the garage

Check the injector washers and the turbo oil-feed filter. If the turbo is replaced, also clean the sump, intercooler and feed pipe, or the new turbo can fail again. Use low-SAPS oil.

Cost cited in the source
