Just to follow up on this thread, http://forums.swedespeed.com/zerothread?id=57344, here are the settings you can choose in VIDA for your DRLs (using an 05 S60 R). The settings are in VIDA under diagnostics->CEM->daytime running lamps. There are 3 different DRL status and 3 different DRL functions:
DRL status:
1) Always on
2) Activated by sensor
3) Off
DRL function:
1) Low beam in all switch positions except parking lamp position (Flex zero)
OFF postion: Parking and DRL or Bi-Xenon are activated based on signal from twilight sensor
Parking lamps: Only parking lamps
ON position: Parking and Bi-Xenon lamps on
2) Light switch works as follows: Off, Parking Lamps and Low Beam (Flexstd)
OFF position: DRLs activated, if twilight sensor reads insufficient light, all lighting is switched off
Parking lamps: Only parking lamps
ON position: Parking and Bi-Xenon lamps are activated
3) Low beam always on regardless of the position of the light switch (Flex low)
OFF position: Parking and DRLs or Bi-Xenons activated based on signal from twilight sensor
Parking lamps: Parking and Bi-Xenons are activated
ON: Parking and Bi-Xenons are activated
If that isn't confusing enough, not all functions will work with each lamp status. (ex. If you choose DRL status Off, you will not be able to select a DRL function).
Just wanted to show that the DRLs can be turned off in VIDA (did not require a software download), and you can choose different settings if you do choose to use them.
It also specifically states you cannot change the programming in the Canadian market.
