Dipped beam headlights always on, no DRL 2016 GTS

Recommended Posts

Hello all, we just purchased a 2016 GTS.  Superb vehicle.  I've sorted through all of the used car issues I have found except one.  The headlights stay on all day even in sunny weather.  The headlight dial does nothing and the red light above the auto position stays lit no matter where I move the dial.  The dipped beam headlight indicator on the speedo stays on also.  So of course DRLs are always off.


I looked through the PCM menus, the lights menu on the speedo, and the owners manual and see nothing that indicates the DRLs could be cut off or the car could have auto or the headlights permanently turned on.


I suspect the previous owner had the dealer alter the headlight function using PIWIS and I will need a dealer or indy with PIWIS to return it to the default mode.


The other thought is a bad rain sensor that keeps the headlights on.


Does anyone have any other input?  Just want to make sure I am not missing a simple solution before I take it into our trust indy next week.


Thanks all in advance!

quick follow up:  secured service records from previous owner, it was a faulty headlight switch.  dealer had quoted him $400 for the fix.  the part was $75, plug and play, replaced in literally 5 minutes and full headlight function has returned.

I believe I have the same issue. I couldn’t find any user settings to change this and I also believe, as you, PIWIS is required to turn off. I also own /drive BMWs and on my bemers it is a software controlled function, not a user setting, which I have turned off.


I have durametric and do not see an option to turn off DRLs.


I want DRLs off on my ‘13 GTS.
