How do you disable the DRL's?

[Westcoaster]

Ok, I don't seem to be getting to far with all of this. I am beginning to think that the DIY HID kit was a bad idea!

I would like to know how to disable the DRL circuit on a Canadian 987? Or at least where the DRL relay is?

Thanks

I don't see a relay. I'd say there is a good chance it is programmed into the Front End Control Unit and would need to be changed with a PIWIS tester.

I don't know the new cars, but I thought if you had PCM you could turn it off, and if you did not then the PIWIS could. There was a question here a few months ago I think, or on rennlist.

I don't know about the PCM opition, but it can be turned off using the PIWIS as Loren has stated.

It's probably another question whether a Porsche dealer in Canada can "legally" turn off DRLs.

[Westcoaster]

ahhh yes, the legality of it all, another aspect to be concerned with to be sure!

Too late tonight to flash up the car, but I thought that I remembered that the fog/driving lights were on during the day anyway?

BTW, my old RX-7 used the driving lights as the DRL's as it had pop up lights.

Maybe the best option other then abandoning the project would be to use relays triggered by the headlamps connections to drive the HID ballasts? The Bi-Xenon equiped Canadian cars run their HID's during the day.

Well, I talked to the dealer yesterday about the DRL's.

I asked if it was normal for all lights to be on for my 2006, he said the Canadian model comes from Germany with the headlights, fogs, markers and tailights on when the car is running, basically everything.

He also said that they didn't know if there was a way to turn off the headlights while the car was running.

I asked if modifying the lights with an aftermarket HID kit would void the warranty, he replied that if there was a problem on the car with an unrelated system then there should be no issue, however (as expected) if there is a problem with the headlights then I would be on my own. But, if I choose a factory Litronic kit and they did the install it would come with a 2 year warranty.

From all of this I think that the only option remaining for non factory HID's is connecting directly to the battery through relays...

Why not just change the vehicle coding for the country from Canada to the United States? This will turn off the DRL feature, yet you can just turn on the headlights to comply with the DRL laws when necessary. You just need to find a sympathetic dealer, which might be easier with a quick trip south. ;)
