Afternoon!

So, as some of you may remember I've had a parasitic battery draw and I believe we've located the issue.

Spent a good part of 4 hours today with a mate going through everything, steps we took are below.

Multimeter set in series between the neg cable and neg battery post.

Car locked & bonnet sensor cable tied down so the car thinks it's closed.

Keys were 5+ meters away (it's keyless)

Car took say 5/10 mins to go to sleep and provide a 0.01 amp reading (meter was set to 10amp scale, believe I'm correct in saying that's 10mA?)

It sat like this for 15 minutes before it shot up to 0.70 / 700mA and stayed like this for no longer than a minute before dropping to 0.01.

Next time, 15 mins later it shot up again. Long story short, we traced it back to fuses 35 / 36 in the UEC. With these 2 removed the car was stable at 0.01 for well over 20 minutes. To verify, we replaced 35/36 and removed 34 (CIM) and within 15 mins it shot up to 0.70.

Again to verify, we replaced all the fuses and removed the HU only. After 15 mins it went up to 0.40. Then we removed the BID and it was stable for over 20 mins at 0.01

Therefore the fault sits with the HU & or BID. Based on this diagnosis, can anyone provide a wiring diagram for these 2 units so we can see if it can be traced to something else or if the actual fault sits with the BID / HU.

Car is an 09 VXR.
The HU is a 2008 build
The BID is a 2008 build

Thanks in advance!
