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.
Specific Modules:
01-Engine:
-- KWP-1281
VCDS works well with all engines available in the U.S. and most engines
that users have tested in overseas markets.
Idle Speed Adaptation (may not
work with APH engines, see your Repair Manual):
With engine warmed up, at idle:
[Select]
[01 engine]
[Adaptation - 10]
Enter channel 01 (Channel 02 for TDI engines)
Enter an adaptation value between 124 and 132
[Save]
The actual idle values and range of
adjustment will depend on the specific characteristics of the engine and
ECU.
Throttle Body Alignment:
See the Throttle Body Alignment page.
Activating Cruise Control on a new ECU (DBW):
Factory fresh ECU's often come with
cruise control de-activated. If this is the case, there will not be a letter
"G" in the Component field of VCDS when connected to the Engine.
[Select]
[01 - Engine]
[Login - 11]
Enter 11463 to activate cruise control
[Do It!]
After doing this procedure, there
should be a letter "G" in the Component field.
02-Auto Trans : --
KWP-1281
VCDS works fine
03-ABS Brakes:
-- KWP-1281 (earlier cars) or KWP-2000 (2001+ models)
VCDS works fine
08-HVAC: --
KWP-1281
VCDS works fine

Recode for warning lamps:
[Select]
[17 - Instruments]
[Recode - 07]
Write down the existing coding for future reference.
Enter 5-digit code from below
[Do It!]
Look at the first two digits in the
coding. Add the values for the options together to get the correct coding.
00 - No available equipment
+01 - Brakepad wear sensor warning active
+02 - Seatbelt warning active
+04 - Washer fluid level warning active
+08 = Seatbelt Warning active (NAR only)
+10 = Seatbelt Warning Driver & Passenger active (NAR only)
+16 = Secondary Display (Radio/Navigation) active
Look at the third digit in the
coding (Market version):
1 - "EU" 24 hour clock
(may result in odometer in km in 2002+ clusters)
2 - "USA" 12 hour clock
3 - "Canada" 12 hour clock (may result in odometer in km in 2002+
clusters)
"The third digit in the code is the country code. The codes are:
4 - "UK" 24 hour clock (should result in odometer in miles)
5 - Japan
6 - Saudi Arabia
7 - Australia
Look at the fourth digit in the
coding (Cylinders):
3 - No Service Interval (2002+
models)
4 - 4-cylinder (1999-2001 models)
6 - 6-cylinder (1999-2001 models)
Look at the fifth digit in the
coding (Distance impulse multiplier):
2 - 3538
4 - 3648 (some 2002+ models)
So, if you want to have Seatbelt
warning and washer fluid warning only in a 2001 Canadian 6-cylinder vehicle, (add
00+02+04 = 06),3,6,2 = 06362.
19 -
CAN Gateway:
-- KWP-1281
VCDS Works fine. This is physically located in the Instrument
Cluster, but functionally it controls communications on the CAN-BUS.
Look at the last digit in the
coding. Add the values for the options together to get the correct coding.
0 - No available equipment
+1 - Automatic Transmission
+2 - ABS Brakes
+4 - Airbags
So, if you want to support Automatic
Transmission, ABS Brakes, and Airbags, (add
1+2+4 = 7) = 00007. Note: 2002+ models do not need to be coded separately
for automatic transmission, so a 2002 with Automatic Transmission, ABS
Brakes, and Airbags, (add 2+4 = 6) = 00006.
22 - All Wheel Drive:
-- KWP-1281
VCDS Works fine. This is the Haldex system on some non-US models.
35 - Central
Locks:
-- KWP-1281
Only on vehicles with manual crank windows. VCDS Works fine.
37 -
Navigation:
-- KWP-1281
VCDS Works fine.
46 - Central Convenience:
-- KWP1281
Only on vehicles with power windows. VCDS fine.
There are numerous options/ features that can be set.
Selective Unlocking:
[Select]
[46 - Cent. Conv.] (35 - Cent. Locking for manual window cars)
[Recode - 07]
Write down the existing coding for future reference.
Enter 5-digit code from below
[Do It!]
Look at the existing Soft. Coding. If you have
selective unlocking (press the unlock button on the remote once to open the
driver's door, twice to open all the doors) the last digit of your coding
should be an even number. To make all doors unlock, add 1 to the coding.
So, if you have a 2-door 2002 GTI that is coded for
selective unlocking (00064) add one to make it 00065 so that all doors
unlock with one press of the unlock button.
Lock/Unlock Horn/Flash:
[Select]
[46 - Cent. Conv.] (35 - Cent. Locking for manual window cars)
[Adaptation - 10]
Channel (03..08)
Adaptation Value (1 = on, 0 = off)
[Save]
Channel 03 Auto Lock
Channel 04 Auto Unlock
Channel 05 Unlock, horn sounds
Channel 06 Lock, horn sounds
Channel 07 Unlock, turn signals flash
Channel 08 Lock, turn signals flash

VCDS appears to work fine. This is the OEM Xenon HID system on some
non-US models.
Headlamp Coding:
[Select]
[55 - H. Light Range]
[Recode - 07]
Write down the existing coding for future reference.
Enter 5-digit code from below
[Do It!]

00001 - Golf 2 wheel drive
00002 - Golf 4 wheel drive
00003 - Jetta/Bora 2 wheel drive
00004 - Jetta/Bora 4 wheel drive

[Done, Go Back]
56- Radio:
� KWP1281
VCDS appears to work fine.
Radio Recoding:
[Select]
[56 - Radio]
[Recode - 07]
Write down the existing coding for future reference.
Enter 5-digit code from below
[Do It!]
Look at the first two digits in the coding (sound
field tuning):
00 - All models with Premium VI w/o
Multifunction Steering Wheel
01 - Golf/GTI
02 - Jetta
03 - Jetta Wagon
04 - All models with Premium VI with Multifunction Steering Wheel
06 - New Beetle
Look at the third digit in the coding (radio/speaker
system):
0 - Premium V or Premium VI (Monsoon)
4 - Premium IV, Premium V, or Premium VI (non-Monsoon)
Look at the fourth digit in the coding
(sound correction):
0 - Premium IV, Premium V, or
Premium VI (non-Monsoon)
3 - Premium V (Monsoon) 2-door or Premium VI (Monsoon)
4 - Premium V (Monsoon) 4-door
Look at the fifth digit in the coding (CD
player/changer):
1 - Without CD Player/Changer
3 - With CD Player/Changer
So, if you have a 2-door GTI with
Monsoon and a CD changer, 01,0,3,3 = 01033.
