Semi-Dynamic Light Install (Audi A3/S3 8V Saloon)

[WhooA3]

Hi,

I’ve just finished installing a semi-dynamic light kit on my Audi s3 8V which I bought from Ash at Audi Retrofits in the UK (@audi_retrofits). These are simply small modules that plug into the back of the existing lights. I was a little unsure how to remove the rear lights, so I thought I would put together an install guide for anyone that is interested. Install time 10-15 mins. Relatively Easy.

Here are the before and after videos

BEFORE


AFTER

Tools
· Standard Audi Toolkit (located in boot with spare wheel).
· From the above, the Torx screwdriver bit (located in the toolkit bag) and the screwdriver main body.
· A trim removal kit which I bought from Amazon – I recommend getting one of these kits. Note: the owners manual Page 268 says to use the plastic spatula from the standard Audi toolkit, but I found it a bit rubbish to be honest.
· Wide masking tape (to ensure paintwork around light isn’t damaged when removing light unit.

Method

1. Use the masking tape to mask around each light fitting. When masking, slip the masking tape in to the gap between the light unit and the chassis. This will help prevent the paintwork being damaged when removing the light.

2. Remove the light as per the instructions in Audi’s manual Page 268 (link here). In summary:

- Instead of using the spatula in the Audi tool kit, use one of the trim removal tools. This is much more effective and less likely to damage the paintwork.

- Remove the trim covering the screws (adjacent to the boot) using a small trim removal tool.

-Remove the two screws on one side of the light fitting (nearest the boot).

- On the other side of the light fitting, use a trip removal tool to pull the unit towards you. Gradually ease out the rear light by pulling alternatively with the trim removal tool in one hand and the side of the light fitting (where the screws were removed) with the other. Eventually the light will pop out.

3. Unplug the light.

4. Plug in the Audi-Retrofits Semi Dynamic Unit. One end into the light itself and the other into the wiring loom.

5. Loosely place the light back into the chassis. Test the hazards / indicators to ensure the light is working as required. Tuck the semi-dynamic light unit box into the cavity below the light. Fix in place using the sticky pad.

6. Removing masking tape and then replace the light properly, screwing in place.

7. Repeat process for the other light unit.

Looks good mate, glad you got them ok.

So all it does is add a delay to make the inner bit flash slightly before the outer bit?

Looking good! What a great in depth write up too! I'm sure you must be over the moon with the results

Looks well but whats the cost of the Modules since the site itself doesn't list any product prices. I was just going to put 2 time delay boards in my self but that looks cleaner for all you don't see it.

Do you get any noise of them, like a relay click when the module activates when the signals are on

I don't hear anything from mine, had them +6 months now. Cost me £150 delivered and they were fitted in about 10 mins (hatch)
