I recently bought an approved Honda and although its under warranty and it will go back for them to fix again. I thought it would be worth posting here in case someone else had the same issue and it may help diagnostics.
The fault is the boot open warning keeps popping up on the IMID even though the boot is shut. The first time it started happening it happened rapidly until the check engine light came on.
Went home noticed the battery was a bit flat charged it up when to work the next day fault persisted.
On the way home in addition to the boot warning popping on and off and the check engine, the power steering, tracktion control and TPS lights all came on.
Locked it up and later that night noticed the rear lights were really faintly lit and pressing the boot catch dimmed them.
Next day flat battery and AA to dealership. They cleared the codes, apparently the rear loom was loose and replaced the battery (with a non-EFB one)
Anyway the fault with the boot has returned 2 weeks later.....
I've seen issues with the boot and drivers door for the MK8 is it still a problem in the mk9? Where is the rear loom connected is this easy to check? I did take it back before for the battery showing low and stop start not working, I don't know if its just a low battery and its throwing these codes because it not charging properly?
The boot light is out when locked...
Any help appreciated I don't have time to keep taking it to the dealer, if they can't fix it next time I'll have to ask for my money back but I like the car
