No ignition, flashing dash lights and beeping
2007 Peugeot 307 1.6 X Line Petrol

Recently a fault popped up saying (Braking system faulty) thought it was the ABS?. Car still drove normally. All of sudden, whilst driving, the car switched off everything, lights and engine. When I tried to turn the ignition, a whole bunch of lights started flickering and beeping noises went crazy plus wipers started moving without any buttons or switches used. There was also clicking noises under the bonnet by the fuse box which I think were the relays?

New faults popped up saying economy mode and anti pollution fault.

I tried the whole reset BSI thing which made the car act normal for a minute but moment I tried the ignition, it went back to its crazy flashing and beeping state.

I used a multi meter to test the Voltage on the battery terminals which read 12.5/12.8V? Is that enough?

I checked all the fuses inside the car and under the bonnet plus the maxis under the fuse box. All were fine and not blown. However, I did see a little oil residue inside one of the ports of one or 2 of the maxi fuse inlets?could that be shorting the electrics?

If it was the battery, surely it wouldn't be flashing and flickering. And surely it would just act dead in general and now allow me put lights on and open windows or even get some sort of life from the dash?

Fuse box concerns me with the slight oil residue which could be causing a short? But if its not that, what about the alternator?

Or maybe the BSI unit is fried?

Any suggestions would be greatly appreciated. Thanks.

As long as that is not when engine running and alternator charging . Check voltage , alternator charging rate when system loaded . Check all earths and especially any from engine / gearbox to body .

12.5v is a bit low....I'd try charging the battery and check connections. A fully charged battery would be anywhere between 13.5v and 14.4v

You are talking rubbish re a fully charged battery and misleading members of the forum with wrong information

12.6V volts
12.6V volts or above
- Your battery is healthy and fully charged. No further action is required. 12.5 volts - Your battery is at a healthy state of charge, but we'd recommend re-checking it within a few days to ensure the voltage hasn't dropped any further.

Voltage Guide For 12v Batteries
A guide for 12v Car, Commercial, Leisure and Marine batteries

A 12 Volt battery contains 6 x 2 volt cells but 12v is the nominal voltage.
The actual open circuit voltage of a 100% charged battery is between 12.70v and 12.80v because each cell is approximately 2.13v
