Ross-Tech is not responsible for any damage or problems that may result from following these instructions. They are to be used at your own risk.

These instructions apply to the VW Passat (NMS/A3) MY 2012+

  • It is always recommended to perform a complete Auto-Scan and save it prior to coding changes. Please see the Online Manual: Auto Scan Screen
  • Never Copy coding from a different vehicle and Paste it to your module(s)!


The installed control modules vary by vendor, firmware level and equipment level, some of the noted tweaks may not be supported by all control modules/vehicles.


[03] - Brake Electronics

On Vehicles using the MK60EC1 ABS system it may be possible to:

  • Alter the HHA (Hill Hold Assist) using the documented [Adaptation -10] Channel while connected to the vehicle.



[08] - Heating/Air Conditioning

Drivers heated seat memory
The Driver side heated seat level (i.e. 1, 2 or 3) should resume the previous level upon restarting the car.

  • Found in Adaptation. From the drop down list, choose Storage of seat heater level driver. Change to On and Save.
    • This may not be supported on all control modules.



[09] - Central Electronics / Body Control Module (BCM)

Note: Make sure to have all Doors unlocked, otherwise this Control Module may not communicate with the Scan Tool / VCDS.


Lighting

All modifications are found in Found in [Coding - 07] > Long Coding Helper unless otherwise noted. Click on each of the Bytes and Bits for the documented options and check or un-check the appropriate boxes as shown in the example below:

[Select]
[09 - Cent. Elect.] Or the module you intend on tweaking as per the list below
[Coding - 07]
[Long Coding Helper]
Click on each of the Byte numbers in row 3) and you'll see the selectable options below. Check or Un-check the boxes for the desired results.

Close the Long Coding Helper by clicking the Windows X box on the top right of the screen or clicking the Exit button on the top left of the screen to send your altered Coding value back to the Coding screen.
[Do It!]
.

Comfort Turn signals Number of flashes and turning On/Off the feature

  • Number of flashes found in Adaptation. Select "Lights: Comfort Turn Signals (Cycles)" from the drop down list, choose the number of flashes and Save.
  • Coding or MFA / dash options may apply to this setting in some cases.

Note: MY 2011 Golf owners reported: Change comfort turn signals count in the VW Vortex

  • Turning On/Off the feature is found in Adaptation. Select "Lights: Comfort Turn Signals" from the drop down list, choose 0 = Comfort Turn Signals inactive -OR- 1 = Comfort Turn Signals active.


Byte 18 - Do Not alter this if you are not retrofitting rear lights !


Alarm, Locking and Coming Home

Options are primarily found in Coding, Long Coding helper. Some Adaptation Channels may be available after enabling coding options.

Alarm Confirmation via lights and horn

Auto-Lock

Auto-UnLock


Windows

Windows up via remote Comfort Operation (via Remote Control)

  • Unfortunately, no known tweaks allow remote windows in the NMS at the present time.


Auto Closing Sunroof & Windows via Rain Light Sensor
Requires the (RLS) light sensor. RLS may not be present on some 2013 models. This will require coding the master [09] - Central Electronics module and the Sub-System RLS.

  • [09] - Central Electronics module using Coding, Long Coding Helper
  1. Byte 4 Comfort Operation Windows/Sunroof via Rain Sensor must be enabled
  2. Byte 4 Comfort Operation Windows/Sunroof via Rain Sensor (Rain Closing) active must be enabled
  • Sub-System RLS (from the drop-down menu) using Coding, Long Coding Helper
  1. Rain Closing active must be enabled



[17] - Instrument Cluster

Seat Belt Light May remove the chime as well

  • Found in Coding, Long Coding helper.


Service Interval Reset

  • Found in Adaptation, Choose "WIV: Resetting ESI" from the drop-down menu.
  • Most North American vehicles with the UDS/ODX protocol instrument clusters have a "Reset" that can be accessed via the MFA, without a scan tool. Pictures here:
  1. Service Menu
  2. Service Reset
  3. Service Info


Modify Service Intervals Mileage and Time

  • Found in Adaptation, Choose "SID: maximum value of distance to service" or "SID: maximum value of time to service"


Fuel Gauge and Fuel Consumption Adaption

  • Found in Adaptation



[46] - Comfort System

Note: The Comfort System known from earlier Models has been integrated with the Central Electronics / Body Control Module (BCM) and is no longer available as a separate Address/Module. All related Diagnostics/Settings have to be performed via Central Electronics / Body Control Module (BCM).
