I know this has been beat to death....While I had my S80 @ the dealer to have a new remote and key programmed, I asked them to turn off the DRL's.. I was standing there when the Tech brought all the modules up on the Screen.. I got a Freebee ETM update, as it showed mine is Failing...@ 73%.. Well, when he went to disable the DRL's, that option was NOT highlighted..as in "Not Clickable" on the screen.. He was hooked into Vida/ Dice etc... 2 techs couldn't figure out why that option to click on DRL was not functional.. Any Ideas? Such a PITA to have lights on all the time.. I know about the safety and all that... but it doesn't matter if you have lights on or not around here...people still drive like dumb@sses...I have a need to be Stealth sometimes with rental houses and Thieves lurking around properties..so I like to catch'em at Gun Point and call the meat wagon to haul them in...kinda hard to do lit up like a landing airplane 24-7.
I'm at the point of connecting an inline switch to the fuse... I don't need lights on all the fricken time..ha haha.. I have HID's in the headlights and the Fogs.. Did the Shunt mod so that nagging Bulb warning is nonexistent now..So any Ideas why the option to turn off the DRL's thru Vida wan't operational?

Thanks

the adjustment for turning them off and on is on the light switch on the dash. I forgot if it was on the front or back, but it is in the owners manual on how to change the setting.

But still I have turned them off on several cars, and back on in some cases and never had a problem. Just had to go into the factory program module settings. I was using a Autologic, not Vida.

 

On the S80? My 96 850 R has that...but the S80 doesn't have the small screw to turn off the DRL's...

 

its on the back.
