This is usually informational. Address it at your convenience.
What the Security / Anti-Theft Light Means on a Citroen Berlingo
On the Citroen Berlingo, this symbol relates to the anti-theft system. A slow blink when parked is normal deterrent behaviour; erratic flashing or a no-start suggests a fault with the key or alarm module.
How Urgent Is the Security / Anti-Theft Light?
In terms of priority, treat this as a low concern on your Citroen Berlingo. The single most useful thing you can observe is whether the Security / Anti-Theft Light is steady or blinking: a steady light generally allows a careful drive to a safe location or a workshop, whereas a flashing light signals an active fault that can cause damage if you continue. Pay attention to changes in how the Citroen Berlingo drives, sounds, or smells, since those symptoms sharpen the diagnosis considerably.

Frequently Asked Questions
Why is the Security / Anti-Theft Light on in my Citroen Berlingo?
On a Citroen Berlingo, the Security / Anti-Theft 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 Security / Anti-Theft Light on?
Short answer: sometimes, but not indefinitely. Given this indicator's low priority, respect the warning colour and the car's behaviour. When in doubt with your Citroen Berlingo, the safe choice is to stop and have it checked rather than risk further damage.
How much does it cost to fix the Security / Anti-Theft Light on a Citroen Berlingo?
Repair cost for the Security / Anti-Theft Light on your Citroen Berlingo 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 Security / Anti-Theft Light reset itself on a Citroen Berlingo?
If the trigger was temporary, a Citroen Berlingo may turn the Security / Anti-Theft 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.
