LEFT DRL LED (UU) flickering on Parking Light function.

[pedroanno]

Update: I'm still waiting for the vcds cable that I got on the web to arrive at my home.

The shop that I installed the headlights made a series of testing, like double checking the cables and everything.

They did a curious test, which was to invert the sides of the headlight. Put the left on the right side of the car and the right one on left side. The result was: ONLY THE LEFT SIDE BLINKS in Parking light(position light), and the rest works just fine.

They put back the original lights and there was woking parking light on both sides, dispite of what I said some posts before(my bad).

And I got the manufacture name: Sonar

I'm very confused.

I changed the values of these channels and it is still flickering.

Any idea?

pedroqnno: good evening. I've been watching your posts with interest and I'm sorry to hear that you problem persists.
Not sure that I entirely understand your issue, but I suspect that more information is needed before suggesting a way forward.

Questions:

1. I assume that your car started with halogens and you installed the LED/HIDs as a retrofit. Is this correct?
2. I'm not familiar with the Sonar kits, but I assume that there was a wiring loom change made to transfer from the 10 x PIN halogen connector to the 14 x PIN LED/HID fittings. If so, what pin numbers from the incandescent 10 PIN connector did you use for the problem lamp (this determines which BCM PIN is involved and therefore which Leuchte-set is responsible for controlling the problem lamp)?
3. If you have read my paper on Leuchte programming, you will have understood that the setting in the "Lasttype" channel for each exterior light tells the BCM what type of lamp is installed. Originally, the "Lasttype" setting for the headlights would have specified incandescent fittings. When you changed to LEDs, did you alter any of the Lasttype settings to LED type for those lamps that were LEDs? The issue here is that incandescent lamps are a voltage device, but LEDs are a current device. When lamps are dimmed, it's important that the dimming process is compatible with the type of light that is installed. LEDs are particularly sensitive to the dimming process and the Lasttype setting establishes this dimming medium
4. A common problem with HID installations that sometimes cause flickering (particularly when LEDs are dimmed) is bad earth connections, loose pin connections and low battery voltage - have you discarded these as a possibility?
5. Have you completed an auto-scan on your car since the new headlight fittings were installed - If so, can you post-up a copy?
6. Have you undertaken an adaptation map for the BCM in your car yet? If so, can you post it on a third party hosting site (like dropbox) and post a link here to the CSV file?

cheers
Don

Hello, Don

Thanks in advance for your help.

Yes, my car originally came with halogen lights and I got this Sonar kit from the web, here in Brazil. The seller told me that was a plug and play device, and the connectors really matches...So there was no physical mods.

I didn't changed the lamp type on "Lasttype" channel. I've checked on your paper(good job) how to do this, and I will modify later today.
The cables and connectors was all double checked.

I'll post detailed photos of these connectors and a video showing the flickering. Also the auto scan and the adaptation map later today.

Kudos from Brazil!

Hi Don.

I have a golf mk7 match and have bought some aftermarket led DRL headlights (GTi style).

The drls work fine until the low beam bulbs are switched on - at this point on one lamp one of the DRL 'hoops' turns off and the other flickers. On the other lamp both 'hoops' turn off.

I'm guessing this is related to the issue you are trying to fix here.

The problem is I can't find the leutch settings on my VCDS, I have searched high and low and can find nothing to do with lighting.

Please help.

Cheers,

Rick
