1 Fault Found:

I've known the company for years and are very good so they won't mess me about with any problems. If somebody can point me in the right direction to resolve this i would really appreciate it!
My friend has cleared the fault off for now but i'm assuming it will return again at some point!
Thanks, hope you're all well
