Peugeot 107 Hazard lights flash intermittently draining battery

Probably something draining the battery overnight. Interior light left on? The regulator in the alternator could be bad and keeping the ignition energized draining the battery. If your jump start it drive to work get off work and it starts after 8-9 hrs you have a system voltage leak some where. If nothing is left on overnight have the voltage regulator tested in the alternator.

Economy mode usually comes on when the computer senses a low charge on the battery and conserves power to start the vehicle.
1. If you can start the car by jump starting from another vehicle with its engine running then you know your battery is the problem. In some cases when you completely drain a battery you have issues with them ever after until they fail completely.

2. If you cannot jump start from another vehicle then turn everything off and disconnect the negative and then the positive lead on the battery terminals and leave it for 10 minutes. Then connect it back up again (positive lead first and then negative lead last) and put the key in the ignition and turn on the ignition but do not start the car. Leave it there for 5 minutes and then turn the ignition it off. Then try starting again.

3. You have not mentioned if there are any other warning lights being displayed on the dash which you have not mentioned in your question. Please check this carefully because it is also relevant to this problem if there are other warning lights displayed.

have checked whether you have any fault with the ignition switch socket?

fault on a live connection,but check all your earths aswell

could be the battery or something draining power from the battery,
when you get home, disconnect the negative battery terminal from the battery, leave it over night in the morning connect it and try to start, if you do not start it means that your battery (although new) has a bad cell thats causing the charge to drain, take it back for warranty. Dont worry about the load test done to check the battery it'f based on the battery's current charge rate not after its left overnight.
If you did start it means something is draining power from the battery, could be,
1.) lights remain on check (hood light, door lights trunk lights) 2.) device remaining on , check radio, ac etc 3.) the cars CPU is draining too much power.
an easy way to check which one is to remove the fuses from the fuse box under the hood for each particular component to turn them off. or you can take the car to a gurage and have them go through all the harnesses for a short.

May be the battery of your car is got completely drained. sometimes by mistake any of the car lights or ac or any battery consuming accessory remains on.And due to this battery gets completely drained and due to no voltage in battery the car does not start.In some cases the car does not gets turned off.If there is a problem in ignition switch circuit and this also drains the battery.Get the car battery voltage checked.It should be 12 volt if the battery is properly charged.This will let you know what is the problem .Also check the battery connections if its got loose then this can happen.------------- Thanks.

This should be done with everything turned off and the door closed. with negative battery disconnected. place 12 v test light between the battery terminal and the cable end.(on neg. side) if the light lites up there is a drain. remove one fuse at a time until u see the lite go out. that is the sytem the drain is on. usually glove box light or trunk light or visor light left on or stuck on.

Check to see how old the battery is, also has it been run down prior to this problem? If it has one or more of the cells may have gone bad and will cause battery drain. If a new battery doesn't fix the problem, have your vehicle checked for a possible short or battery drain.

aftermarket stereo? dome lights? car alarm? Use a multimeter and see what fuse has power draw when car is off.
