Honda Accord 2007 Battery Drain after 3 to 4 days, I couldn't find the problem so booked it in for a basic 1 hour diagnostic check at my local Honda.

Honda Dealer Technician located it to a faulty HFC Blue Tooth Control Module (RRP £2,000) so just disconnected the multi pin plug, to solve the Drain issue. But I was told by the Service Receptionist that another Tech with a 2003-2007 Accord had the same issue, so obviously a known problem.

Search the forum, parasitic battery drain is a known problem and always the Bluetooth module

Essy fix. I did mine in 5 mins. Think I found fix on YouTube. Very common fault.
