Electronic Power Steering (EPS) Light on a Alfa Romeo 159

How Urgent Is the Electronic Power Steering (EPS) Light?
Urgency level for this indicator on the Alfa Romeo 159: high. Reading the colour is the fastest gut-check — a red symbol asks you to stop and investigate quickly, while amber or yellow means schedule a check soon rather than immediately. Green and blue symbols are simply telling you a system is active. Whatever the colour, the safest habit is to note when the Electronic Power Steering (EPS) Light appeared, how the Alfa Romeo 159 is behaving, and whether the light is steady or flashing, because a flashing warning almost always means act now.
