Hi everyone.
I have bought a 2003 S80, 62K on the clock, full history, 1 owner.
No alarm siren or LED light on dash.
I have read its good to replace the siren. Is this the best way to go?
I look forward to some help.
Thanks,
James

 

You may have car configuration without alarm siren. Just central lock.

 

Thanks for the reply, its much appreciated.
How can I check the car configuration as the guy hat sold it, 1 owner said it was alarmed and i get the alarm service message on the dash?
Thanks again.

 

Even if the car was not configured with a siren, shold the red LED on the dash flash. Also the internal sensor button on the dash doesn't work (turn off or on)
Thanks.

 

Usually that means you need to replace siren.
