Snapdragon,
I think I'll have a go at that. Just to clarify: Linking the sidelight to the DRL and coding the Sidelight as a LED makes the car think both are LEDs so no more error? The downside is that the DRL stays on with headlights but as you say it dims so no dazzle. Sounds like a fix Stew,

Looking on Audi-Resource site I see under Coding, Central Lecky
3 X X X X : Bi-xenon headlights with LED daylight driving lights and AFS Would re-coding to that make the car stop throwing an error on non LED DRLs? Just a thought..... PS What is AFS?

The outer lights are bi-xenon, the inners have 21W DRL + 5W sdelight. Between these is a side-facing 35W cornering light. Yes, I just put that small LED in the photo, in the sidelight holder (small W5W or T10 wedge) so it didn't shine yellow, as this will now always be on with the main DRL bulb. I didn't include a photo, but my new yellow wire is connected to the +ve on the DRL just as it is on the sidelight in the photo. I would do the coding first, as it is probably safer and I can vouch it has no ill effects. Also check it doesn't cause an error if you don't have cornering lights. |

Yes, I coded a 3 instead of 4 there. This coding immediatly turns off the 21W DRLs and cancels the broken bulb error on the dash - but it also makes the sidelight bulb on in the day and glows like a glow-worm at night, effectively you no longer have sidelights because they are so dim. That is why I ran a link wire from the sidelight to the DRL (now swapped for bright LED). The 1156 LED and W5W LED are now on in the day without an error code, and is dimmed to 9% at night or when parked. This is how cars that came from the factory with LED DRL work too. I shouldn't get any more MOT advisories about DRL error warning which may be an MOT failure now that they are supposed to check for any warning lights - not sure if the DRLs are included in this scope. A better but harder way would be to remove the headlight plug and swap the two pins around in the connector if you have a pin extraction tool. Note before I modified anything, coding for LED DRL did not cause any error messages on the dash or in VCDS, so if you code for that and get errors due to a different headlight, then it may not be worth proceeding.

if you do this bit as well , you get it controllable from the MMI
0 X: Daylight driving lights not selectable via MMI 1 X: Daylight driving lights selectable*** via MMI (default: Off) 2 X: Daylight driving lights selectable*** via MMI (default: On)
