307 electrical problems

    Having only had this car for 2 days (I bought it privately), I've had a
    couple of niggly electrical problems which I wonder if anyone can shed light
    on. Previous owner denies any knowledge of these faults.

    I bought the car 2 days ago and all seemed fine. This morning I noticed that
    the clock and date had re-set themselves overnight. The date was showing
    01-01-01 and the time was showing 01.00

    I re-set this to the correct time / date and went shopping. On returning to
    the car the boot wouldn't open! I could hear the switch clicking as I tried
    to open but nothing! Eventually opened it with a screwdriver from inside.

    This evening I went to the car, time and date are wrong again, but now the
    boot opens!! I tried wiggling the cable loom next to the boot hinge in an
    attempt to make it fail again, but it just kept on working. Drove to the
    filling station, tried the boot, and yes it wouldn't open again.

    Can anyone suggest what's going on?

    Many thanks
    Chris

    The boot opening problem is normally a broken wire where the loom passes
    into the boot. But since you have checked that.....
    However there is an interlock on the boot (well on my SW of the same year
    anyway) where you can't open the boot if the engine is running unless you
    open a door first, or something like that.
    The other issue is likely to be a bad earth connection somewhere. It is
    possible that you could get the fault codes read which will give a hint.

    Yes, mine also has the interlock. - I think it goes that the boot won't open
    if car has driven over 4 mph unless a door is opened first. I've tried
    opening each door, and none allowed the boot to open. Car recognises that
    the doors were open though as the display on the dash indicated them as so.

    There are only 2 wires going to the boot "handle" switch, so how does it
    receive the pulse to open the catch? Is it from those little plastic
    "things" each side of the boot slam? If so I suppose it could be them at
    fault.

    More ideas please.. I'm not paying Peugeot to spend hours on this unless I
    have to!

    This morning clock and date is once again "re-set" to 0

    Come back my old 504 where everything worked so well :eek:(

  4. Clock sounds like you have no permanent feed to it, holding the memory up.
    You obviously have a switched live as you can reset the clock. Could be a
    fuse. Reset and then turn off the ignition and recheck the clock an hour
    later this should let any residual voltage die.
    There are often a pair of magnets in the side of the boot that operate reed
    relays to show the boot is open or closed. These could be the plastic things
    you describe. The interlock is a solenoid that operates with two wires if
    you can hear it operating you either have a mechanical fault or the battery
    voltage is low at the solenoid not allowing it to operate fully. Check with
    a meter when you operate the lock that it has full voltage at the solenoid.

    k and date is once again "re-set" to 0
    Hi
    The clock reseting happened twice on my wifes 307 sw before refusing
    to start- turned out the battery was faulty.

    Thanks for all the above replies. I may have found the problem with the
    boot. One of the magnets (thanks Mike) was not in it's clip properly and
    was moving about when the lid was shut - perhaps this was enough for the
    solenoid to fail when trying to open??

    I'm going to get a new battery fitted as this one is sometimes reluctant to
    turn the engine over with any great enthusiasm.

    I don't have the code for the radio - does anyone know if these 307s need a
    code to be entered if the battery is removed??

    Thanks

    Wire a 12 volt supply via the cigar lighter before you disconnect the
    battery.

    I'm not really sure, but I don't think you need a code to reactivate the
    radio.
    I have read somewhere that the radio is programmed to work only in your car.

    No you don't need a code for this, the radio is matched to the car VIN.
    However, be very careful when changing the battery, there is a fixed routine
    to follow, if you don't you can end up with all sorts of problems like the
    immobiliser no longer working, and having to pay both arms and at least one
    leg to Peugeot to get the keys reprogrammed.
    The routing goes like this as far as I remember. Open driver window. Leave
    car with doors closed (bonnet open) for at least 5 to 10 minutes for the BSI
    to go to sleep. Then change battery. Leave again for at least 10 minutes,
    then lean in open window and switch on lights. This should be enough to wake
    up the BSI and then all should be OK.
    I have had a problem in disconnecting the battery in that it wouldn't start
    afterwards (before I discovered the above) but waiting 10 mins or so did
    restore everything.
    Of course you could just hang a small 12v battery across the terminals so
    that you keep a constant 12v supply to all the computer gubbins.

    Thanks to everyone for your help! Car now sorted with new battery, clock and
    calendar which don't re-set and working boot latch.
