Urgent Assistance :warning light issue due out of market windscreen fitted

I took my vehicle for a service at Land Rover The Glen, and everything was in order at the time. About a week later, warning lights began flickering on the dashboard. I contacted Land Rover The Glen and booked the vehicle in for inspection. I was informed that they could not resolve the issue, as it is being triggered partly by a windscreen fitted with a non-Land Rover part.

I then contacted ABSA Insurance and was advised to request a letter confirming that the issue was caused by the aftermarket glass. I submitted this request but have received no response to date, and the problem persists.

If I am unable to receive assistance with this matter, I would like to understand what I am paying insurance for.

Please could someone urgently look into this issue and assist.
