VW Golf/Golf Plus (5K/52) Tweaks

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 Golf/Golf Plus (5K/52/AJ) 2010+ and the VW Jetta (5K/AJ) MY 2010 only.

• 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 Adaption Channel while connected to the vehicle.
  

• Enable Indirect TPMS using the documented Long Coding Helper information and the forum feedback here: How to: retrofit indirect Tire Pressure Monitoring in 5 minutes. (7K6)
  

[08] - Heating/Air Conditioning

Drivers heated seat memory

• 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, Long Coding Helper unless otherwise noted.

Daytime Running Lights - The lamp systems are different:

• Factory Xenon (or Halogen DRL's that are using the main low/dipped beam) – Byte 11
• Factory Halogen (generally when using a separate bulb or filament for DRL only) – Byte 15
  

Cornering Lights via Front Fog Lights active

Notes: The lights may work under the following conditions:

• The headlights must be turned on and the steering wheel must be in the turning direction.
• The headlights must be turned on and the turn signal must be on in the turning direction.
• Also see Byte 17, Adaptive Light/Cornering Light Variant. This seems to control the fogs as cornering lights with turn signal.
  

Fogs as Daytime Running Lights for Xenon equipped vehicles or Halogen equipped using the main low/dipped beam

• Byte 11 - Un-check "Daytime Running Lights (via Low Beam) active"
• Byte 14, Bit 1 - Manually modify the binary value from a "0" to a "1"
  • Also see: Using the Long Coding Helper when checkboxes are not present
    

Fogs and Xenon Headlights as DRLs (Both) for Xenon equipped vehicles or Halogen equipped using the main low/dipped beam

• Byte 11 - leave this alone (DRL's on)
• Byte 14, Bit 1 - Manually modify the binary value from a "0" to a "1"
  • Also see: Using the Long Coding Helper when checkboxes are not present
    

Fogs as Daytime Running Lights for Halogen equipped vehicles or using a separate bulb or filament for DRL only

• Disable Factory DRL's in Byte 15 - un-check "Daytime Running Lights (via separate lights) active"
• Byte 14, Bit 1 - Manually modify the binary value from a "0" to a "1"
  • Also see: Using the Long Coding Helper when checkboxes are not present
    

Notes: Depending on the Byte 18 coding, this may result in all of the parking lights illuminating.

Front and /or Rear Fog Light dimming behavior with High Beams
Depending on equipment level, two separate coding bits should be available.

Comfort Turn signals

• Found in Adaptation. From the drop down list, choose the number of flashes and Save.

Note: MY 2011 owners may want to see: Change comfort turn signals count in the VW Vortex

Emergency Brake Warning active This actually uses the 4 ways flashers, not a flashing of the brake lamps.

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

• Some additional notes can be found here: For those with Byte 18 issues... (MK6)

• RoW (non US spec) Byte 18 discussion here: DRL's - tail lights deactivation

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

Coming Home

• Several Bits may control CH options such as Manual or Automatic.
  • Note:If the vehicle is not equipped with an "Auto" headlight switch and a (RLS) light sensor, coming home activation will likely require you to pull the high beam stalk back briefly after shutting the vehicle off and before exiting. The description should be found in your owner's manual.
    

Leaving Home

• Leaving home will likely require the "Auto" switch and a light sensor. The description should be found in your owners manual.
  

Coming Home/Leaving Home via Fog-Lights and Parking lights

• Found in Coding, the Adaptation values for the duration of time are not affected.

Windows

Windows up via remote Comfort Operation (via Remote Control)

• Found in Adaptation. Channel 6, change the value to 1 (On) and Save.
  
  • Note, If this feature turns off after other coding modifications, see the Long Coding Helper for additional Coding enabling.
    

Auto Closing Sunroof & Windows via Rain Light Sensor Requires the (RLS) light sensor. Forum information found in these locations:

[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).
