In this video, we see the engine light on an Iveco Daily: this light can indicate various issues: problems with the DPF that has become clogged, a faulty NOx sensor or catalytic converter; low AdBlue level; dirty injectors; malfunctioning fuel pump or fuel contaminated with water.

Other reasons could be a lambda sensor not performing well, or a dirty MAF, a damaged MAP sensor; oxidized wiring or a temporary error in the control unit (which sometimes resolves with a reset).

The most common errors are related to the DPF and EGR, especially in urban driving; for Euro 6 models, the most frequent problem concerns AdBlue, while for older models, the most widespread error is oxidation.
