Good morning. I own a 2016/17 discovery sport. Recently had one of the headlights replaced as is was cracked. The new light side light does not work. It comes on when you turn the lights on then goes off after a second or two. Car has now failed the control technique so unable to drive it. Is this a software issue? The garage I use seems unable to find any information. And won’t use the land rover garage here as has bad experience in the past.
