BlueOnBlue just make sure you have the most recent PSzData file for use with Esys. Here's how to VO code it without dealer finding out.
Note: just make sure the headlamp is switched off before proceeding — just as a precaution.
* Connect with Esys - Target Selector: choose the i-step that most closely matches your car version. For G20 that's S18A_xx_xx (select the most recent.) DO NOT select any of the options prefixed with "xx_DIRECT." Under Interface, select 'Connection by VIN.' If your VIN is not listed you have an issue.
* Hit Connect button
* Under 'Vehicle Order' click on Read
* Under 'Vehicle Order' right-click on FA and choose Activate FA if required
* Under 'SVT Actual', click on Read (ECU)
* If it's the first time you have coded, right-click on ECU under the SVT tree and choose 'Read Coding Data'. Use Windows File Explorer to backup your CAF directory which by default is C:\Data\CAF
* Save your FA and SVT
* Under Editors and Viewers - select 'FA Editor' and load your saved FA
* Click on SALAPA-Element find and remove 5AP from the list. Click on Apply Changes
* Click on File > Save As. Give it a name e.g "FA_no_5AP"
* Switch back to Expert Mode > Coding. Load the FA you just created with no 5AP and do Read (ECU) again.
* Select the following 5 ECU's in the SVT pane:
BDC_BODY3
HU_MGU
FML (both of them)
KAFAS4
* With the 5 ECUs selected, click on Code (not Code Default Values; doing so might require a trip to dealership.) Alternatively you can right click on each and "code"
* Check the report is Green for all 5 ECUs. Warnings are OK, but the text should be Green. Any red texts suggests you have a problem
* That's it! Congrats: anti-dazzle now works. Simply push the button on the left stalk to activate auto high beam.
