DHG,

I've been thinking about your post some more and as well as not saying 'welcome to the forum' with your first post I should have really thought some more as 99% of owners wouldn't even know how to do a parasitic draw test; so I guess you have covered all the basic checks on battery and alternator.

Basic checks:

Parasitic draw checks, really drawn out by an American:

So am am wondering if you have a more obscure issue. A drain through the alternator is an example which can vary with temperature due to a breakdown in the diode pack leaking to earth. Another D3 specific issue is a fault with the EAS. The air suspension does wake up after a while to check and adjust the level of the car. It may be worth leaving your meter on for a few hours to see if the draw during self-leveling is excessive, which may indicate a wiring, connector or sensor issue. Other random faults can 'wake' the car too causing excessive current draw.

Disabling the meter time-out function and setting min/max mode is useful here (if the meter has such modes or if you can borrow one that does) as you can set it and forget it for a while.

Hope this helps.

I have issues is this video ok to follow Robbie ? I’ve seen some saying the vehicle needs to go to sleep to be able to see what’s staying live ? I presume by un hooking the terminals to apply the test in that video will awake the car ? Or is that ok ?
