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

Vince

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
dealer

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
6579KT
EMERGENCY CALL BATTERY
WITHOUT HYBRID TRACTION CHAININDEPENDENT TELEMATIC UNIT or until OPR 12900
it seems to be quite expensive 115,22 € in Peugeot Servicebox
