Hello,
I'd left the Alarm lights on for 1 hour , then came back and car would not start. It doesnt even make any sound when i turn the ignition on.
All the electronics work inside the car and I get these two messages :

Anti-Skid - Service Required

and


Immobiliser - See Manual

Replaced battery and still nothing. Some engineers work on the issue, but they can't find anything.
Unfortunately there is no Volvo Service in my town.. It will cost me over 250euros to get it on the nearest Volvo dealer.
Any last ideas ?

 

Usually this is a sign of low voltage - but if you replaced the battery, you may have a cabling problem (ie ground strap etc?) or you may have accidently set the immobilizer.

Can you try locking/unlocking the doors with the fob a few times to see if that resets the immobilizer? Next is to measure voltage (say at the fuse box not the battery posts). Otherwise you may have a faulty SCU (start control unit)... Also make sure you have your car fully in park and other control buttons are not set.
