Right chaps, got my cable as above and it works a treat, haven't come across anything yet that it can't do and I've been playing for many hours.
The point of this post really was to say that I have managed to illuminate the front DRL's (side lights, NOT fogs) without the rear lights coming on
If anyone is interested in doing it as I know it has been discussed many times on different forums, this is how I done it after many many trial and error attempts.
BTW - I am not responsible in any way if you **** up your coding, this is a
guide as to how I got mine working so take care.
This for VCDS 10.6.4.
Car - 2010 (October build) CR170 FR
Open VCDS and check the communication with CAN first.
Select Control Module
Select Module 09 - Central Electrics
Select - Coding 07
Click on Byte 15 (or Byte 00 and toggle along with up & down arrows) and tick bit 6 '
Daytime Running Lights (DRL) via seperate Lights active'
Click Exit or red cross or press Esc.
IMPORTANT - Copy the long coding in the original coding box and keep it safe, this will return the car to the original settings should you drop a bollock or this method does not work on your car.
Click Do It.
Click OK (if box says new coding is accepted)
Select - Coding 07
Click on Byte 24 and tick bit 07 at bottom '
Daytime Running Lights (DRL) as Position Lights active'
Check Byte 18 and see what your lights are set to in the drop down menu (forgot to take screenshot), mine were set to Standard set up...not Golf, Tiguan, Tuareg, Altea etc etc
Click Exit or red cross or Esc.
Click Do It
Click OK
Click Close Controller, Go Back
Click Go Back
Click Exit and Exit VCDS
Turn off ignition and unplug lead.
Now then, I have side lights as DRL's on the FRONT ONLY and no bulb warning messages, all other lights function as they should.
If you are in any way uncomfortable with this then DON'T DO IT.
I've also enabled the gauge sweep (very cool) and the alarm chirps when locking / unlocking but removed them after 1 day as they were getting on my tits. This VCDS is a great tool to have.
