Unticked in Installation list but still in Auto Scan

1) Open bonnet
2) disconnect negative terminal and connect multimeter in series?
3) lock bonnet with screw driver
4) lock car

Essentially, does it matter if you lock the car and then disconnect the battery and reconnect it through the multimeter? Does this rewake all circuits?

So, the current draw should be 0.02Amps or 0.02mAH... as I am getting 0.03/4 at the moment after 5 minutes.

Thanks so much!

Yes, it matters. It will wake the car up again, and probably set the alarm off.

Even if it does wake up, you'll need to wait til it's asleep again. So 20 minutes or so.

I tested the batteries Voltage this morning and it was down at 12.28v from 12.57v yesterday at 4pm. So there is a drain happening - I might swap the gateways again today with the newer one to attempt to code it once again.

I did as instructed and the AMPS were between 0 > 0.02 after 35 minutes. I watched for 5 minutes and did not change.

I am not sure how this is possible since my gateway is a 1K0 907 530 E @ 0110.... It shouldn't be compatible, in addition the voltage dropped quite significantly overnight.. can anyone comment?

I wouldn't be too concerned about the overnight voltage drop — a battery just off charge will have a 'surface charge' that disappears in a fairly short time, and this drop will increase as the battery ages.
It's what I'd expect to happen.

The current drain doesn't look out of place either, the receptor for your locking system needs some flow to keep it awake, as do various other bits.

.02A is 50 hours for a drop of 1A — if your battery is, say, 60AH?

Thanks for the reply -

Well the battery is only 1 year old and has only ever been totally flat 1ce... so is it normal for it to lose charge that quickly?

What is the minimum required to start the car?

Could it be that it will spike again sometime after 35 minutes? I haven't left it connected for longer? I simply do not understand how my gateway 1K0-907-530-E from a 2005 GTI could in any way be compatible with the RCD510....

My battery is a original VW 12V 72Ah battery... it still does not make sense why after it is dead after 2 weeks...? Maybe there is a spike at a later time after 35 minutes? is that even possible... why would a module wake up again.

Why don't you take it to an independent VW workshop who has the right equipment and knowledge for testing?
To test the battery drain you need an equipment that will record min/max reading over the long period of time, like overnight. But, also they will be able to test the battery for you.

It wakes up because there's either a wiring fault in the CANbus network, or the gateway is faulty.

Re-test for spikes after 20 minutes with old gateway, but without the RCD510 connected.
