Have you checked that the battery terminals are tight

Hi I did what you said still nothing left the live off the battery had a brew connected it still fault showing
I hit the panic button it said stop in red on the dash !!
So I drove it around the block came to a junction anchored on
Pressed the brakes a few times and weird it’s now off !!

Like I say was perfect until the bloody eBay tracker so I just like you said retraces me steps

Fingers crossed it’s ok

Thank you so much for all your help
