Battery and sensor issues

[Tilton 73194]

 

Hi all my f-pace has  a really strange issue so recently the engine management light came on I have a pal who works for a motoring organisation who connected his computer to the obd port which flagged up a faulty cam position sensor. He cleared the fault but we noticed that after locking the car the hazard triangle and the 2 front door lock lights stayed on resulting in a flat battery we’ve been monitoring this problem for a couple of weeks now. So in summary if I don’t clear the fault the battery is fine but as soon as we clear the fault the car won’t shut down after it’s locked resulting in a flat battery the following morning. I have bought a new battery and it has been in to a main dealer where they monitored it for 48 hours they used I believe it’s called a peakascope that basically said that everything was shutting down as it should..hoping someone can shead some light on this problem for me,thanks
