Credov's researched list of the 2 faults the Mazda Demio XD is known for (2014–2018), 2 of them serious or costly. Each one says what to look for when you check the car, so you can spot it before you buy. Not every car has these faults: they are the ones worth checking on this model.
What to look for: Pull the dipstick for oil above the full mark or smelling of diesel, and watch for a flashing DPF light.
Why it matters: Oil diluted by diesel is thin and wears the engine and turbo faster, and a DPF that cannot finish regenerating can need a forced regeneration, a professional clean or a new filter, so the dipstick and the DPF light are worth checking on any short-trip diesel of this family.
What to look for: Watch for the glow-plug light flashing, and listen at idle for one cylinder knocking louder than the others.
Why it matters: Driving on with a failed injector risks fuel further diluting the oil and damaging the engine, and a full set of injectors is a big bill, so the glow-light and idle-knock checks are worth doing on any diesel Demio or Mazda2 of this generation.
