Car will not start at a certain temperature, usually after being stopped once hot. Immobiliser is locked on.
Caused by the immobiliser unit slipping and touching the bottom of the fuse box. Heat soak once the car is stopped overheats it and causes it to malfunction. It will stary working again once car cools down again and heat in that area dissipated.
Cure is to put it back in place properly, and heat wrap it.
This took BHM a lot of experimentation over many hours, and I am very glad it was under warranty! No parts costs, a good 6 hours at least in labour to find the fault.
On the plus side, the electrical systems on my car were completely checked, and it had full diagnostics run several times - so now we know that those connections are all good and in the right places!
*fingers crossed, just because I don't want to jinx anything...
