    Thanks for the advice Mawey - appreciated. Unfortunately not that simple. Have tried a different battery and still have the same problem. Just going to have to take the time to pull each fuse when I get my hands on a multimeter. A pain but better than garage prices to find the problem

    Hey guys,
    Normal shutdown time for a BM is 16 mins,although E46 normally shut down within minutes.Best thing to do is open the doors,bonnet and boot,and roll the catches,and pad out the microswitches on the strikers as well,basically tell the car that its ready to sleep.Leave the glovebox light ON and leave a map reading light ON.If the car is an auto you have a built in indicator of when the car has gone to bo bo's....the gearposition light in the shiftgate(orange light).When this goes out the car is sleeping,also the glovebox and map reading lights should be out by now.Now check what your drain is.Watch the clock and the lights closely.They may go off (i.e they have been told to go asleep by the ZKE)and then come back on again,i.e the car has been woken.Best way to try and diagnose these drains is an inductive probe measuring current.This will enable you just clip the sensor over the wire and get a current reading,its also really quick for isolating circuits too.Try and stay away from disconnecting the ZKE,and fuses for the ZKE as this should be a last resort or the ZKE will wake up and then you may have to wait another full 16 mins which can be a real pain in the a$$.Good luck

    take the rechargable light out of the holder in the glove box, then check the current drawn, car is asleep after about 15 minutes, or when the light goes off near the gear stick.

    Hey

    I had a similar problem with my e46 compact.

    Turns out it was the hedgehog resistor that was totally shot. Replaced it and a new battery and the car has been spot on, from a battery point of view.

    I had the same problem with a 1999 528iSE E39. After much investigation it turned out that one of the main radiator cooling fans was U/S and draining the battery constantly. Some considebale ££ later it was all fixed and running OK.
