says it all, that does
it only means that p38's are a high tech bit of kit and need looking after,just like any thoroughbred does.

I suppose its fair to say that the flame that burns the brightest , doesn't last as long.

the flame has never flickered or died.it might have dimmed once but came back stronger and brighter than ever.

But that would defeat the purpose of it as the battery drain would still take place through the fuse!!

Have you checked which version of the RF Receiver you have? It could be you have an old one which is causing the BECM to be woken up continually by various wireless signals. It's a very common cause of battery drain.

if it is the rf,just disconnect the blue wire from it and see if that stops the batt drain.

RF reciever is located under the rear parcel shelf thing on the drivers side. It's a little black box with two wires (i think)
If you open it up you can compare it to the photos of the models that datatek posted and find out if yours is the newest version, although if you haven't replaced it yourself I'm going to guess it won't be.
As an alternative you can remove the aerial wire from it and then you'll only be able to unlock and lock the car from close to that rear window but it might stop your battery draining if it is the RF reciever that's the issue.

The BECM always has power, but it should go into sleep mode a short after after switching off. Normally it's a case of the RF receiver keeping it awake if the battery goes flat, in which care just the aerial wire should be disconnected not the power.

This was happening to mine when my boss owned it. If he parked next to a certain office block it would drain over 8 hours but if he parked it elsewhere in the car park it was okay.

this can also happen when parked under certain car park lights.my friend often gets called out to our local massive shopping centre to sort this problem out.he makes a fortune out of the centre management for doing this.
