What the Auto Start-Stop Light Means on a Seat Exeo

Frequently Asked Questions
Why is the Auto Start-Stop Light on in my Seat Exeo?
On a Seat Exeo, the Auto Start-Stop 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 Auto Start-Stop Light on?
It depends on the urgency (low) and how your Seat Exeo is behaving. If the light is red or flashing, or the car drives differently, stop safely and get help. If it is amber and everything feels normal, you can usually drive to a workshop soon — just do not put off the diagnosis.
How much does it cost to fix the Auto Start-Stop Light on a Seat Exeo?
There is no single price for the Auto Start-Stop Light on a Seat Exeo; 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 Auto Start-Stop Light reset itself on a Seat Exeo?
If the trigger was temporary, a Seat Exeo may turn the Auto Start-Stop 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.
