Battery drain still happening... Completely stumped :( **UPDATE**
marko:
So what value of amps is being drawn from the battery when the car is locked ???
In my opinion the battery is not really the issue..something is draining the storage in the battery regardless of weather it's the right size battery or not.
Lock the car with bonnet open and put amp clamp across the cables on the battery and get the reading after about 5 minutes.
What version can gateway is fitted??
Aftermarket radio??

If eddie did it correctly all current drains have been checked... so in theory its not a parasitic current draw problem.
MJ:
I'd make sure that everything on the canbus network is 100% in sleep mode.
Any single wire faults indicate a can bus system error and will potentially mean certain control units remain in an awake state, which will flatten the battery pretty quickly.

Yea Eddie did check every single fuse and then waited until everything was sleeping and every single time he did it they all went to sleep. He must have checked them about 5 times over.
This is so frustrating as I just wanna get it sorted. I can't keep coming back to my car to find it not working :/
MJ:
So he did a current drain test from the battery terminal?
