Like the majority of cars on the road a Tesla is not that much different when it comes to windscreens, generally, most people will go through their insurance company to get the glass repaired or replaced, others will simply call a reputable glass repair/replacement company.

What should I do? What are the steps?

  1. Work out whether a repair or replacement is required (guide below to help you check), if a repair is possible speak with a repair company to have it fixed ASAP, this can normally be done on your driveway or by taking your car to their local facilities. It’s worth doing this as quickly as possible before a crack can form.
  2. If a repair doesn’t look possible, check with your insurance company, make contact with a reputable windscreen repair/replacement company &/or contact Tesla for some quotes
  3. Make a note of the part number of your windscreen – This is fairly small text on the windscreen but due to previous changes by Tesla could be important.
  4. Book your appointment to replace the glass, provide the part number (Failing that or as well tell them the year / VIN / AutoPilot version)
  5. The glass will be sourced (often directly from Tesla) and a date provided for when they will come to replace it
  6. They will come (if it’s a Model X in pairs) to replace the glass with specialist tools – Some may require the car to be taken to a specialist location for fitting
  7. After it’s replaced the car’s camera system located within the windscreen area may need to be realigned (how this can be done by the installer can be read below).
  8. Once the glass has been replaced you will most likely be told to wait at least half an hour minimum before driving and no washing of the car for 24 hours.

How to work out if a repair is possible?

Watch this guide but basically, if it’s in front of the driver a 1cm repair is possible, to the left of the driver (if standing in front of the car) 1.5cm repairs are possible, to the right between 1.5cm-2.5cm or if right at the top of the windscreen, on the furthest area away from the driver or anywhere else up to 4cm (as long as the damage is greater than 3cm away from the edge).

1cm = pinhead
2.5cm = 2p coin

 

What part number do I need?

It’s important to confirm the exact part number that’s on your car currently but the following are a rough guide:

Can anyone order these part from Tesla?

Yes it’s available over the counter without a VIN.

The repairer isn’t using official Tesla glass will that matter?

Companies such as Autoglass (or more likely the insurance company covering the costs) may use/request none official Tesla glass (primarily for AP1 cars), to effectively save money (it’s rumoured to be £200 extra to buy the glass from Tesla). It would appear there isn’t any noticeable difference but you should have the right to request a like for like replacement although that will depend on your agreement wording.

The repairer is saying I need to have the windscreen calibrated by Tesla, is this true?

No this is false. Here is the wording that Tesla sent to Autoglass:

Tesla update on camera calibration procedure

Tesla has recently updated its vehicle software to include clear calibration procedure. These options are now available in each vehicle’s touchscreen under the Service tab when running 2020.32 or later software.

What does this mean for your company?

The update will allow you to perform windshield replacements and camera calibrations without having to connect the vehicle to our diagnostics tool. The customer will have to drive until the system indicates calibration is complete. If the customer drives more than 100 miles or Km and the calibration hasn’t completed the vehicle will need a full calibration to inspect/adjust the camera pitch inspection.​

The customer will be shown the following alert if they attempt to activate features that require a fully calibrated camera “Continue driving to allow cameras to calibrate

What happens next?

Because the windshield is replaced by your company, the customer will have to return to your location for complete calibration. In order for this to be executed access to the Tesla Diagnostics tool is required, as well as the training on how to use the tool. Tesla service locations will not complete the calibration due to liability and warranty reasons. We strongly advise to inform the customer appropriately.

When is the calibration procedure unsuccessful?

The procedure might be unsuccessful if the camera has been moved too far out of position during the windshield replacement procedure or the windscreen bracket is misaligned. 

Why is it important to clear the camera calibration data?

Changes to camera pitch could influence the performance and behavior of the Autopilot features and cause unexpected behavior. Clearing the calibration data will force the camera to self-calibrate and make the system operate as designed.

What exceptions are there?

The Tesla vehicles equipped with 1st generation autopilot  (prior to 2015) will need, at all times, calibration via the Diagnostics tool.

How to obtain access to the Tesla Diagnostics system?

Access service.teslamotors.com and purchase one of the subscriptions including diagnostics. Questions on this process and how to obtain training can be sent to [email protected]tesla.com
