Just bought a 308 and the alarm randomly started going off. It wouldn't stop with key or wouldn't stop when I started ignition. Can anyone shed any light please. Tried to Google but nothing productive.
Wot he says, don't mess with it, go back to the vendor. Remember any fault appearing within the first 6 months is deemed to have been there at the point of sale unless the vendor can prove otherwise. So it is down to him to fix.
My alarm was going off every couple of minutes and central locking would stop working too on my Peugeot 308cc (Year 2009). i checked the bonnet switch and this looked fine. It was down to the Shunt Fuse being in the parking position (saving power if your going on a holiday for a week or 2) instead of the client position. Changed fuse to "Client" position. Also would lose the capability of unlocking the car via the remote after 10 mins as well as resetting the date back to 2007. I bought the car for repairs and this was one of the faults that was resolved.
