As I said, the Audi A3 and a4 and a6 with Xenons/LED headlights have LED indicators and when the indicator is on, the DRL white LED dim, so that the orange LED can be seen.

They flash bright/dull 180 degrees out of phase with the indicators. This was standard from the factory behavior.

They dim while the indicators are on - not while the indicator is lit, so the off point of the indicator 'flash' is still indicator on, just lamp not. The DRL stays dim throughout the indication process. It is illegal to have flashing (which would include dim/bright/dim/bright) white lights at the front of the vehicle unless for emergency vehicle use.

DoT advice is as follows:

 

DRL placed close to direction indicators may also automatically dim when the direction indicator is active. This is to ensure that the direction indicator is not masked by the light from the DRL

 

Make of that what you wish ............ seeing as it doesn't define 'active' - does active include the unlit phase????? How can a light be masked by another if it is not currently lit?

 

Can of worms - make your own minds up, all at your own risk etc.

Hey,

 

sorry to unearth this thread... I recently got a conflict by activating the DRL blinking in phase with the indicators.

 

I had previously activated the fog lights as CH/LH, and it worked great until I activated the aforementioned tweak. Now the fog lights still light up, but so do the headlights...

 

Any idea on how to resolve this conflict ?

 

Thanks in advance !

 

PS: Car is a MY15 Octavia RS

Please post your adaptions map. That will help with diagnosis

I did the adaptation via OBD eleven, so no way to post it I guess :/

 

I double checked everything, and even tried to go back to the previous settings (so no more blinkers in phase with DRL). The headlights still light up with the fog lights for CH/LH....

i have mine out of sequence (indictors on the DRL is off) and i think that looks cool too. tho anyway apart from staying on all the time looks cool 

I managed to extract some backups I did with ODBeleven (one before, and one after the changes). I made an excel sheet to compare the values of the before and after, and nothing changes... (except the changes I made)

Any ideas ?

Okay my bad, I’m a new kind of stupid....

 

Completely forgot that I missed this part... Works now

Hi, just to confirm, this tweak will not work on a MY18 O3 (ie. Split headlights) as the indicator and drl is the same strobe. Correct?

Yes the facelift DRL switches off completely and allows the orange indicator to flash. It's quite satisfying to see it in the reflection of the car in front!
