Me and a buddy switched cars and went for a drive yesterday. He took my '13 A4 and I drove his '12 328i. He was following me and I noticed when we stopped at a traffic light that the LED switched off on the side where the turn signal was activated. I had never noticed that before. Looked carefuly for other A4s and noticed they were the same.

I struck me that someone who doesn't know this might think it's an issue with the car. Has anybody ever had problems with cops thinking your daytime runing lights had a problem and stopping you for a verification?

 

You can VAG COM the LED's to stay on. Check audizine for coding.

 

All B8"s do this and I've never heard of anyone being challenged by police about it. The idea is to enhance the visibility of the turn signal to oncoming drivers. I've changed mine so that the DRL wink is at 50% rather than full on or off.

 

I'm sorry, but being new to Audi's, I don't have a clue what the lingo is about!

 

How does one go about doing this?

 

Almost all new vehicles (regardless of make) have this feature. Regardless of LED DRL. It's meant to make the turn signal more noticeable to oncoming traffic during daylight hours.
But if you don't want this feature, it can be disabled with VAG COM software.

 

VAG COM is "Volkswagen Auto Group Communication". This a proprietary language that all VW Group cars use to communicate with "Smart" components throughout the vehicle. Not only the engine but all systems and sub-systems. In short it's the Laungauge the car uses to talk to itself. Ross-Tech makes software for the consumer that when installed on a PC laptop can plug into the car. From there a mechanic or owner can diagnose or reprogram or test virtually any component on your car. Including telling your car to leave the DRL on when the turn signal is activated! Pretty cool eh??

 

Ah!...many thanks for the clarification.

 

The LED's stay on when using the turn signals when your head lights are activated, noticed that last night.
