battery

Gadgetz · Mar 14, 2013

my battery keeps going flat when not used for 4 to 5 days. had it tested at the local auto shop and he said it was ok? Obviously it isn't so want to test it off the car before buying a new one. Will leaving the car without a battery connected cause me problems, ie with things needing resetting etc? cheers in advance. oh its a 99 2.5dse auto.

The signal from the remote control button on the key is picked up through an aerial built into the rear right window then is passed to the locking / alarm system. The age of the system means that this will pick up all sorts of modern signals so the car doesn't get the chance to 'sleep' so it flattens the battery. Disconnecting this aerial usually stops it picking up the signals.

The problem is that the radio receiver for the remote key (RF receiver) is sensitive to the same frequencies as wifi/wireless doorbells etc, and so keeps the car computer (BeCM) awake, thus draining the battery. The solution I'm afraid is to spend a completely unreasonable £150 or so on an updated version which only responds to the key signals. However you can provide a temporary solution by disconnecting the aerial for the RF receiver so it doesn't pick up many signals. This does make unlocking the door with the remote a bit tedious but it's still possible, and at least the car still starts once you're in!
To disconnect, you need to remove the rear, right parcel shelf in the boot, and find the little black box. There's a single blue wire connected to it - the aerial. There is also a wire cluster - DO NOT disconnect that because that will freak out the BeCM, and nobody wants that

And don't be tempted to buy a "bargain" new RF receiver off a well known auction site - it will be an old one resold as the new type. Go to someone reputable like Island4x4 and cough up your £150 smackaroos.

I asked Island 4x4 how much it was as it now says POA on their website for it and its £175.

The price seems to be steadily rising, I wonder if Land Rover's stocks are running low?

Quite possibly, it says on their website "Please call so we can check availablity from our supplier before ordering ."
