It was too difficult to identify the source of the drain but when the battery was replaced the current drain dropped back to virtually normal for the various small items that had to remain live to some degree, central locking, radio, etc.

So it seems that if the battery is not fully up to the correct voltage some item in the car was not fully disconnecting when the ignition was turn off. With a fully charged battery the item turned off correctly. confused2 confused2 confused2

Peter would you like me to come around with my FLIR camera and see what is hot! It'll be the various instrumentation adaption modules along with the Immobilizer, you'll probably find a hot CANBUS or LINBUS chip or two.

Alternately remove the fuses and see when it stops then investigate what is hanging off the end of said feed.

Mark, that's a smart idea. May I ask what you are using for the FLIR ? Is it s bolt to a smart phone or some dedicated device.


Just time to burn a little more petrol before dinner.

Just the FLIR one add-on for my phone

Last thing I used it for was searching for a wasp nest at night in the hedge at the bottom of my garden!
