What the Electronic Power Steering (EPS) Light Means on a Volvo C40
The EPS (electronic power steering) light on a Volvo C40 indicates a fault in the electric steering assist. Steering can become noticeably heavier, and the system may need a diagnostic reset or repair.
How Urgent Is the Electronic Power Steering (EPS) Light?

Sometimes a simple engine restart resets a one-off EPS glitch on a Volvo C40; if it keeps returning, get it scanned.
Frequently Asked Questions
Why is the Electronic Power Steering (EPS) Light on in my Volvo C40?
On a Volvo C40, the Electronic Power Steering (EPS) 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 Electronic Power Steering (EPS) Light on?
For a Volvo C40, a steady amber Electronic Power Steering (EPS) Light with normal driving generally allows a careful trip to a garage. A red or flashing light, or any change in performance, means you should stop and avoid further driving until the fault is identified.
How much does it cost to fix the Electronic Power Steering (EPS) Light on a Volvo C40?
Repair cost for the Electronic Power Steering (EPS) Light on your Volvo C40 depends entirely on the root cause. Because the same symbol covers cheap and expensive faults alike, a proper scan-based diagnosis is the best money you can spend — it turns a guess into a precise, fair quote.
Will the Electronic Power Steering (EPS) Light reset itself on a Volvo C40?
Sometimes the Electronic Power Steering (EPS) Light on a Volvo C40 clears on its own once the condition that triggered it no longer exists — for example after several good drive cycles. More often, though, the light stays on until the underlying fault is repaired and the code is cleared, so treat a self-clearing light as a reason to still investigate.
