P38A '99 4.6 Vogue

Hi,
I've just bought a '99 p38 that was locked 3 years ago with superlock and the battery went flat. The car was towed back to previous owner's house where it has remained ever since. I can get into the car through the tailgate. As yet I haven't put a battery on it and want to have a clear plan before I do. I obviously don't know why the battery went flat in the first instance as I believe the car was only left for a short period. Is it possible that one of the superlock motors tried to continue to run?
As I've not had a Range Rover before, a step by step process would be really helpful.
Thanks in anticipation.

Hi Nick:
There's a sub-section on here all about the RR tech stuff. It's called RAVE and can be downloaded.
If you can pop the bonnet and get a battery on then I would try entering the EKA code for the vehicle which should cause it to unlock and re-enable the fobs etc.
Do you have good new batteries in the fobs, it will need them eventually. I attach an abridged set of instructions. Good Luck!

Battery drain is a common problem with the p38 there are a few causes but the main one is interface from wireless devices, get it unlocked and running then there is things to check for the battery drain.

A flat battery is unlikely to be due to the lock motors.
As Brian said RF interference is the most likely cause, MK 1 & MK 2 FOB receivers are not too good, they respond to all sorts of RF signals waking up the BECM and flattening the battery.
A faulty alternator is another possibility as is a failed battery.

Thanks for advice so far. Not likely to have time to play for a while due to work.

Do you know what battery is on vehicle currently?

I would advise same as I was told - sort as many electrical gremlins charging the dead one, then get a decent one first as last from battery megastore.
1000cca 120ah type 31. I have no regrets and it was a lot of money to me.

You can drop test your battery, check alternator Is throwing out good power and check your RF receiver in back panel see if it’s connected and what colour dot it is.
