Replacing an EV windscreen? Confirm the camera calibration and cover

Before authorising the job, get two answers: who has approved the glass and costs, and who will complete the manufacturer-required camera calibration for your exact car. A fitted windscreen and a cleared warning message are different evidence from a completed calibration.

1. Confirm cover before booking outside the approved route

Open your own policy schedule and glass section. Write down the excess, any separate repair/replacement limit, approved repairer route and what needs prior authorisation. Do not assume every comprehensive policy, third-party policy or independently booked job has the same cover. Ask the insurer or authorised claim handler to confirm in writing the proposed glass specification, calibration cost, any separate specialist visit and what you must pay. If manufacturer-branded glass is important, obtain approval rather than assuming it will be funded.

If there is no glass cover, request an itemised self-pay quote that includes the required calibration or names who will do it and at what agreed cost. Do not compare a glass-only price with a complete replacement-and-calibration price.

2. Identify the car and the repair capability

Give the repairer the exact model, year and fitted camera/heated-screen/head-up-display equipment so the correct screen can be identified. Supply registration/VIN privately through its legitimate booking route when needed, not in public comments. Ask whether it can carry out the manufacturer’s procedure on that exact version. EV propulsion alone does not identify the glass or calibration method.

Autoglass explains that camera position can change when glass is replaced. A static calibration uses workshop equipment; a dynamic procedure involves driving. The manufacturer’s repair method determines the job. Do not ask to skip a required calibration because the camera was not unplugged or the dash looks normal.

3. Agree what completion evidence you will receive

Thatcham Research’s ADAS repair position calls for the fitted systems to be identified, the relevant repair method followed and auditable calibration results retained. Its record checklist includes vehicle identity, date, repairer/technician and equipment. Ask for a copy showing the affected system, outcome and any limitations or unfinished work, alongside the glass invoice/job sheet. A scan that merely clears fault codes does not, by itself, show a required calibration succeeded.

At handover, check the paperwork relates to your car and this visit. Ask the repairer to explain any failed/incomplete result and its safe-release advice. Retain the authorised quote, completion record and aftercare instructions together.

4. Warnings remain, or calibration could not be completed

Record the exact warning and when it appeared; do not deliberately provoke lane-departure or emergency-braking intervention to test it. Contact the repairer and insurer/claim handler with the job reference and ask who will arrange and authorise the outstanding diagnosis/calibration. If the provider lacks support for your version, require an agreed specialist route before paying for a second attempt. Keep a dated record of the response.

If visibility, steering or safe control is affected, stop safely and arrange assistance. Otherwise obtain explicit professional advice about whether the car may be driven and which assistance functions are unavailable; do not rely on those systems pending resolution. Do not enter service menus, move the camera or attempt a home calibration.

One Financial Ombudsman decision involved uncertainty over whether the correct calibration software had been used after a windscreen replacement. It illustrates why the actual result and repair capability matter; it is an individual decision, not a promise that another claim has the same remedy.

Copy this booking question: “Please confirm the approved glass, my total contribution, the manufacturer-required calibration for my exact car, who performs it, the completion record supplied, and the agreed route if it cannot be completed.”

Next: check repair and vehicle documents when buying used · understand static and dynamic calibration before booking.
