I changed the headlights in my base mk7 1.6tdi from halogen to aftermarket mk7.5 style LED lights with dynamic indicators. I now have this vehicle report that says check right daytime running light/ side light. There is also a light on my dash of a yellow triangle with a “!” mark inside it. Is there a way of removing this error and light from dash. Thanks

More info needed!!
- What specific headlights were fitted?
- did you install a cross wiring harness? If so, which harness did you use?
- what coding changes were made?
- what is the specific error message on the scan report?
- what were the manufacturer's instructions about the DRLs?

VLAND headlights were fitted. No coding changes were made. No extra wiring harness was used it was a direct plug and play unit. There is no fault code just the error on the dashboard saying “check right side light/ running light. Manufacturer gave no extra coding instructions.

hmm....... VW never made a system for retrofitting LED based headlights onto a car that was factory fitted with incandescent headlights! These VLAND assemblies are therefore non-OEM and it's anyone's guess how they are designed. And dispite the manufacturer's marketing claim for "plug-and-play"- my experience with non-OEM equipment is that they rarely are plug-and-play !! So, how to proceed? Well....... if this was my car, I would first determine if this problem is either a wiring issue, or if it is a coding issue. On RoW model mk7/mk7.5 Golfs, the headlight connector on the wiring loom for a car that is factory built with incandescent headlights has a total of 10 x pins (not all pins are populated with wires). On both car-side connectors, the DRL signal on the VW wire-loom is terminated on pin #4. First-check is to eyeball pin #4 on the 10 x pin headlight connector. Notice that on the car-loom side of the 10 x pin connector, pin #4 is terminated with a wire. Does the connector on the VLAND connector have a wire terminated on the mating pin #4?
- If not - then this is your problem. You will either need to ask the manufacturer/seller for information about which VLAND pin is used for the DRL function on their headlights. Or, you could search the VLAND side connector for a pin that doesn't have a mating wire that is terminated on the car-side connector and assume that this is the VLAND DRL wire. Then de-pin this wire and re-position onto pin #4.
- If so - then turn-on the DRLs and using a multi-meter, check that volts appear on pin #4 on the VLAND side of the headlight connector
If the 2nd test above is OK - then let's discuss a possible coding solution in response to your confirmation in another post
