Frequently Asked Questions
Why is the Electronic Power Steering (EPS) Light on in my Volvo EX90?
On a Volvo EX90, 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 EX90, 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 EX90?
Cost varies widely because the Electronic Power Steering (EPS) Light can stem from several causes on a Volvo EX90. Some fixes are almost free — tightening a cap or a connector — while others involve a sensor or component and its labour.

Will the Electronic Power Steering (EPS) Light reset itself on a Volvo EX90?
Occasionally, yes — a Volvo EX90 can extinguish the Electronic Power Steering (EPS) Light by itself when the monitored value returns to normal. But a light that keeps coming back is a clear sign of an unresolved issue that needs a proper diagnosis rather than repeated resets.
