He said to check the angle sensor with the diagnostic tool and if it's not at 0 degrees when the steering is right, it must be reset/re-initialized. Steering Angle Sensor Calibration - Scroll down to the 'Lost Angles' section near the end, especially the last three paragraphs. #2 jerrymildred, May 14, 2018. But, most tools recommend that the calibration be performed on a level surface.Launch X431 Series tools are able to reset steering angle sensor for multi brand vehicle manufacturer.And some diagnostic tools are designed to specific vehicle brand.
This article shows methods of how to reset steering angle sensor.Two methods are introduced in this article.And you can read related article or video to get more detail information in this article.Hope it is helpful!
What is Steering Angle Sensor?
The steering angle sensor (SAS) is a critical part of the ESC system that measures the steering wheel position angle and rate of turn.
When you need to reset the Steering Angle Sensor?
The Steering Angle Sensor need to be reset or recalibrated after an alignment is per formed or parts in the steering system are replace.For example:steering wheel,airbag spring contact,steering column,etc…
How to reset or recalibrate Steering Angle Sensor(SAS)?
1) Self-Calibration:
Some newer vehicles can auto calibrate by having the wheel turned from lock to lock and then centered and cycling the key.
Step 1:Turn the steering wheel first as far as it will go anticlockwise and then as far as it will go clockwise
Step 2:Turn off the engine and remove the key from the ignition
Step 3:Remove driver side wheel, stop and pack vehicle
Step 4:Turn off ignition, remove key, wait 10 seconds
Step 5:Start engine, confirm normal Active Steering operation
Here show a case of how to remove steering angle sensor for Benz C230 (Video Guide)
And here show the video guide on resetting steering angle steering for Mercedes Benz GLK550.This procedure can be used on any Mercedes.
2) Scan Tool Steering Angle Sensor Reset
There are many options for OBD2 tools to reset SASs. Some tools can even configure the size of tires. But, most tools recommend that the calibration be performed on a level surface.Launch X431 Series tools are able to reset steering angle sensor for multi brand vehicle manufacturer.And some diagnostic tools are designed to specific vehicle brand.

What is steering angle sensor:
The steering angle sensor (SAS) is a critical part of the ESC system that measures the steering wheel position angle and rate of turn. A scan tool can be used to obtain this data in degrees. The SAS is located in a sensor cluster in the steering column.
Opel Tech 2 and Op-com, which is better for SAS reset:
With Tech2 you don’t need a PIN code.
Saab doesn’t have PIN code like Opel.

Here is the procedure with Tech2:
Calibrating the steering wheel angle sensor
Note
The wheel alignment must be correct before calibration is carried out.
1. Put the wheels straight ahead.
2. Connect the diagnostic tool.
3. Select Steering Angle Sensor Calibration. Follow the instructions displayed.
4. Read and clear diagnostic trouble codes.
5. Test drive the vehicle.
Op-com steering angle sensor calibration:

- 1. Disconnect the battery and the steering angle sensor lose its basic setting
2. Remove airbag and steering wheel following the usual precautions
3. Move the center rotor of the CIM to align the 2 triangles
4. Connect the op-com interface with computer via USB port than install the software
5. Plug the op-com unit into the vehicle USB port after succeeded installing software
6. Op-com will turn out the ESP light but not very first and second time
7. Turn on the vehicle ignition switch and start the vehicle.
8. Drive in a short distance straight line on a level surface at the speed not higher than 20 km/h.
9. When the steering wheel is straight, stop the vehicle with the wheels pointed straight. Make sure the vehicle is not move again.
10. Come to the op-com main function menu, select “Op-com Diagnostic”>> Vehicle year “2006”>>Vehicle model “Astra-H”>>Body>>CIM (Steering Column Module. >> Measuring block 3>>Steering Angle Sensor offset – set to 0.00 by slightly moving steering wheel
11. Back to the CIM screen, select “Programming”. Enter the security code if the system asks for it. Then click “Yes” when the system accepts the security code.
12. Go back to the programming screen, select “Steering angle calibration”, if the system still showed steering angle calibrated, choose “No, choose Activate and waited”. Otherwise, select “Yes” when the system displays steering angle calibrated.
13. The ESP light then came on with ignition as normal and went out after a few seconds
FAQs: steering angle sensors (SAS)
How long have steering angle sensors (SAS) been in use?
These sensors have been in use on certain vehicles since the early 1990s, but became commonplace by 1998.
Why does the SAS need to be calibrated or reset after a wheel alignment?
Because it is required by the OEM.
Improvisation advice exists in the form of note coloration, database of licks, and automatic lick generation from grammars. 
Grammars can be learned automatically from transcriptions.
When did OEMs begin requiring SAS reset with alignment?
Some as early as 2003, others as recently as 2008, though some 2008 models were specified as early as 2002. Hunter’s WinAlign software has always provided vehicle specific screens that advised technicians that special equipment and software would be required to complete the alignment.
Why am I just now hearing that SAS need service?
Because many newer on-board systems such as electronic stability control and electric power steering rely on accurate input of the driver’s intentions. This input is provided by the SAS)
Why do some OEMs require SAS reset in conjunction with alignment on only particular models or model year of vehicles?
Each OEM has their own specific selection criteria on which vehicles are affected.
Why don’t all OEMs require reset after alignment?
Each OEM has its own service requirement criteria. Most OEMs have only added the requirement in the last few years. Some as recently as 2008.
Does the SAS need to calibrated or reset if thrust angle is not changed during the wheel alignment?
Yes. Thrust angle is only one of many conditions causing the SAS to report a value other than zero when the front wheels are steered straight-ahead based on the thrust angle.
Why do some SAS reset procedures require the vehicle to be driven a given distance to complete the procedure?
Each vehicle manufacturer develops the SAS reset procedure based on the technology and design of the system. In some cases, a test drive is needed for the vehicle’s ECM to verify proper operation. CodeLink will indicate which specific vehicles require a test drive.
They quote hue, value, chroma values, and indicate they are from the 1905 Munsell description of color: The system of colour notation developed by A. Munsell in 1905 identifies colour in terms of three attributes: HUE, VALUE (Brightness) and CHROMA (saturation) [] HUE (H): Munsell defined hue as the quality by which we distinguish one colour from another.

Steering Angle Sensor Failure
Do SAS automatically calibrate themselves after the vehicle has been driven a given distance?
On some vehicles, SAS is automatically calibrated; on other vehicles, it is not. In either case, OEM mandates determine whether SAS reset is required after wheel alignment. Always follow the OEM’s recommended service procedures.
What may happen if the SAS requires calibration or reset and the process is ignored?
A variety of symptoms may result from a SAS reporting inaccurate information. Examples of such symptoms may be a shutdown of the electronic stability control system, untimely application of individual brakes, steering wheel vibration or a vehicle that drifts of pulls in one direction.
