Did anyone have issues with the vehicle not going into complete hibernation /IBS(Intelligent Battery Sensor) issues / Battery Discharge Warning/ Stop/Start witch remaining on and pulsing into an off stae despite the vehicle being untouched for hours on end.....

Does the vehicle have a tracker unit?

When i encountered the problem i did some reading and there was a way to check/test if the IBS itself is faulty(bypassing or removing, i cannot remember right now).

Also theres a micro power module in the spare wheel well ( i think) of the Pre lci. It was moved in the lci, but they are prone to damage if any of the grommets in the spare wheel well are worn/damaged/lose/lost as dampness and water can get in.

Check the module for any signs or damage or wear, not sure how to test it though

Yes it does

Yes it does

They can be the cause of battery drain issues...

I have removed checked - There are no modules in the spare tyre well (even under the bottom cover).

I have checked the resistance across the fuses (after the vehicle went into hibernation). Readings show that the functions linked to the 'On' State of the Stop/Start switch are active.

The quesion is whether the it is the Stop/Start itself ? How do I test this ?
