Battery drain after Columbus firmware upgrade

[Tom Watson]

Hi All

I have upgraded the firmware on my 1T0 035 680A from the link in this forum to 3810 for the early A version. The
can-gateway is as below

Address 19: CAN Gateway Labels: 1K0-907-530.lbl
Part No SW: 1K0 907 530 Q HW: 1K0 907 951
Component: J533__Gateway H16 0202
Revision: H16 Serial number: 2700K087170117
Coding: ED807F0E4006021303
Shop #: WSC 73430 790 00000
VCID: 356BD69A25D1

I believe that this should not have a power drain issue that is covered in this and many other forums, but the battery flattened itself overnight. There is now a frequent 'click' from the passenger side of the car, I believe it to be a relay. There is also a fan noise that coincides with the fan running in the Columbus.

Has anyone else had this issue, or could it be something else?

I dont have a working copy of 2764 that was in it so can't downgrade back to it.

Any advise/help will be greatly appreciated.

Tom
