SOS Button flashing red

368 Views 5 Replies 4 Participants Last post by  perrye
Hi everyone. Have a 2012 508 SW 2.0 HDI.

It had some work done on it and the battery was disconnected for a period of time. I had to set the date and time and stuff but noticed that the Red SOS button on startup now does:

a) Briefly flashes green
b) Starts to flash red and off intermittently
c) After about 5 minutes goes of and remains blank.

Car shows 'no faults' when I press the check button.

Any idea what it could be? Everything else seems to work fine (apart from the hud is stuck but that's a different matter)

Many thanks

Is it possible SOS button uses 3G network and this network no longer works in your area?
I know G3 network in Slovenia will be shut down at 30.6.2023.
Just a thought... I don't know what network SOS button uses.

On page 268 of the 508 manual it says this:

If the orange LED flashes: there is a
system fault.

If the orange LeD is on continuously: the
backup battery must be replaced.
In either case, contact a PeugeOt

The location of the battery? Can't find anything on the interweb so maybe a secret known only to Peugeot (maybe). Hopefully it isn't the same as the location of the BWM emergency assistance systems (under the headliner at the back of the car)

Would a BSI reset possibly rectify it or is it possible the system is just being phased out and it will become just another useless button.

The best picture I could find is this, battery is 14. Hope this helps.

If your battery is
it seems to be quite expensive 115,22 € in Peugeot Servicebox
