Power Steering Warning Light on a BMW i3
Have this checked promptly. It is not an immediate stop, but do not ignore it for long.
What the Power Steering Warning Light Means on a BMW i3
On the BMW i3, this light indicates a problem with the power steering — hydraulic (low fluid) on older cars, or electronic on modern ones. You can still steer, but with noticeably more effort.
How Urgent Is the Power Steering Warning Light?
How worried should you be? For the Power Steering Warning Light on a BMW i3, the urgency is high. A good rule technicians rely on is 'colour plus behaviour': match the warning colour against how the car is actually performing. If the BMW i3 still drives normally and the light is steady, you usually have time to plan a proper diagnosis; if performance drops or the light flashes, err on the side of caution and stop safely.

Frequently Asked Questions
Why is the Power Steering Warning Light on in my BMW i3?
On a BMW i3, the Power Steering Warning Light comes on because a monitored value crossed a threshold the car considers abnormal. It could be a simple, inexpensive cause or a genuine fault — the only way to be sure is to scan the vehicle and interpret the codes rather than guess from the symbol alone.
Can I keep driving with the Power Steering Warning Light on?
Short answer: sometimes, but not indefinitely. Given this indicator's high priority, respect the warning colour and the car's behaviour. When in doubt with your BMW i3, the safe choice is to stop and have it checked rather than risk further damage.
How much does it cost to fix the Power Steering Warning Light on a BMW i3?
There is no single price for the Power Steering Warning Light on a BMW i3; it ranges from a no-cost adjustment to a component replacement. The honest way to control cost is to diagnose the exact code before authorising any repair, so you only pay to fix what is actually wrong.
Will the Power Steering Warning Light reset itself on a BMW i3?
If the trigger was temporary, a BMW i3 may turn the Power Steering Warning Light off automatically after a few drive cycles. If it remains lit, the vehicle is telling you the fault is still present, and the symbol will only go out for good once the cause is fixed.
