This can't be the first person in 4 years that has replaced a windshield with ASG and a lift. Methinks there is some confusion here.

On a side note, if you leave your bypass cable connected, they can't do the calibration after they've installed the glass and it's not like they're gonna tank it out again. I would love to see some true tests between calibrated and uncalibrated though.

Interesting that OP hasn't returned to comment on all the confusion. What's up OP? You don't generally recalibrate glass, unless you move it around ever so slightly within the frame. That's almost an impossibility. You do recalibrate sensors or cameras or radar units etc...

Looking at the FSM, there is a procedure. Pretty basic, it does say to do it when a windsheild is replaced or Tire diameter has been changed.

There are two possible codes that would require it as well: Calibration not learned Diagnostic Trouble Code (DTC) (C008F-00) or Sensor Adjustment Required DTC (C14A4-00) are present

Basically, the process is to put an angle gauge on the fins of the module and get it at -1* by adjusting an alignment screw, then
1. After completing the vertical alignment, connect the diagnostic scan tool to the vehicle.
2. Select the “DASM ECU” and then select the “Miscellaneous Functions” tab.
3. Select and run the “DASM Auto Alignment” procedure and follow the on screen prompts to complete DASM calibration.

Awww, come on guys, it's so simple maybe you need a refresher course.

Hey! It's all ball bearings nowadays. Now you prepare that Fetzer valve with some 3-in-1 oil and some gauze pads, and I'm gonna need 'bout ten quarts of anti-freeze, preferably Prestone. No, no make that Quaker State.

Recalibrate the Camera's or sensors maybe? My tesla is going in for a windshield and will have to have this done by the installer, maybe she just interpreted the info wrong.

What is ADAS?
ADAS stands for “Advanced Driver(s) Assistance Systems”. These systems rely upon cameras, lasers, and radar – often with the camera mounting to the windshield. Any time a new windshield is installed, the camera must be calibrated to ensure proper functionality and to restore the camera to OEM specifications.

Examples of ADAS applications are:
  • Lane Departure Warning
  • Collision Warning
  • Blind Spot Monitoring
  • Park Assist
  • Automatic Cruise Control
  • Pedestrian Protection
  • Headlights Control

Easy peasy. Pull up perpendicular to a 6" curb and have them calibrate based on the top of the sidewalk.

Post author here to clarify: Satellite and Dealership service department used the word "recalibrate" to me... if it's the wrong word maybe they thought "a lil lady" wouldn't understand true vernacular?

Anyway, the official issue is "DASM Auto Alignment Procedure will not complete if vehicle is above stock ride height. ACC & FCM systems will not complete in WiTech after windshield has been replaced... DASM will report COO8F and/or C14A4 faults. This could be caused by aftermarket wheels, tires or lift kit."

So strange that a 2" lift and 35" wheels would cause problems to a vehicle the manufacturer assumes will be modified. I still haven't found an answer. Thank you to those working this out in their own jumbled brains, too!

To start from the beginning. Why did you have the dealer recalibrate? Was it because the windshield replacement threw the code?

If so, I'd think the sensor was knocked out of alignment during the replacement.

If not, why was it recalibrated?

If every vehicle on the road had a lift kit would the problem go away? Lift 'em all!
