Hi. Thanks for the quick reply. It seems to be in a reboot loop. About every five minutes. I went online and carried out the tests on my V6 box and it found nothing wrong. I've power cycled 3 times. The faultfinding algorithm does not allow for my problem so I never get to the opportunity to book an engineer.
Online chat says there is a 24hr wait time to chat. All very frustrating! I'll try the 150 tomorrow if nothing happens overnight. Cheers
