I found a PDF document. If anyone else needs this as a time saver :
Section 8.
-----------------------------------
VCDS settings.
Use vag-com and turn the key on. Go to 01-Engine and change the soft coding from
0001 to 0002. Keyswitch to the off position immediately after. Clear all the fault codes,
after running the engine, no faults should return.
Next for the 6 speed go to instrument and click on recode and change the last digit from
a 2 to a 4 to set the proper pulse rate for the 6 speed transmission. Save and Exit and
cycle the key. The purpose is to set the pulse rate properly for the speedometer and the 6 speed
transmission.
On MY 2001 and earlier, go to CAN-bus gateway>coding and change the 7 to a 6 to
remove the automatic transmission feature.
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. In my Golf, the coding was 7 so I changed it to 6 which
subtracted the automatic.
Not necessary on MY 2002 and later. However, It has been discovered that some 2002
and later cars are having TCU communications error codes even though the wiring and
coding was done correctly. If the 19-CAN Gateway is checked with these cars, the value
is 6 as it should be. What is interesting (thanks to “the*rogue” for this one) is that if the
value is changed to a 6, which it already is, and saved, it forces the ECU to rescan the
devices and finding no TCU, it is now happy and the codes do not reappear.
Make sure you cycle the key after each change and then check for fault codes.
Trouble shooting a rough running engine after recode.
Now start the engine. It might run rough but in vag-com, go to engine>login
(12233)>adaptation>block 1 and see what the IQ is. You will probably see something
like 0.5 +-. You will want to do the hammer mod (see tdiclub.com how to section) to
bring this number to something like 4-5 as it was before the recoding.
