A few solid routes for the Q4 e-tron, depending on whether you want an OEM-style glow or a more “show” setup:

1) OEM+/factory-style look (cleanest)

• Audi OEM ambient lighting retrofit parts (if your trim didn’t come with it)
  Best integration (brightness control, color themes, no random remotes), but it’s the most expensive and can require coding and dealer-level part matching by VIN/trim.

2) High-quality aftermarket “OEM-like” kits

• Kits built around Osram/HELLA-grade components (sold by VAG retrofit shops)
  These are typically the closest to factory diffusion/brightness with better reliability than generic kits. Look for Q4/ID.4-specific harnessing and CAN-safe dimming.

3) Feature-heavy RGB kits (most customizable)

• Govee RGBIC interior kits (value + app effects; best for footwells/under-dash accents)
• OPT7 Aura / similar (brighter “neon” look; more visible hotspots if not diffused)
  Good if you want lots of effects, but they won’t look factory unless you spend time hiding strips and diffusing them.

What I’d prioritize for a Q4 e-tron

• Q4-specific fitment (dash/door contours matter a lot for avoiding hotspots)
• Diffused light guides (not bare LED strips)
• Proper dimming (ideally tied to the car’s illumination circuit, not a cheap PWM box)
• No CAN-bus errors (use an add-a-fuse/illumination tap, not random OBD power)

Quick recommendation by goal

• Most OEM-looking: OEM retrofit (or a VAG retrofit shop kit designed for Q4/ID.4)
• Best bang-for-buck accent lighting: Govee RGBIC (footwell/console areas)
• Most intense/custom: OPT7-style kits, plus diffusers

Great info, saved!

sooo i did some digging into the market and honestly, it realy comes down to two options:

- **Generic Fiber:** Cheap but basically looks messy during the day.
- **Acrylic Integrated:** These mimic the OEM look by fitting flush into the trim gaps.

The integrated kits are definitely better for the Q4's geometric lines. I'm super happy with my setup; it looks totally premium and the app control is actually decent!

Seconding the recommendation above! Adding my two cents, but basically, I've tried many different setups over the years and honestly, cheap kits are a trap.

In my experience, you gotta be CAREFUL with the 12V power vs. tapping into the door wiring. Here's why:

- Tapping into the door panels looks cleaner, but if you mess up the harness, it's a massive headache to fix and might void parts of ur warranty.
- 12V is safer for DIY, but you'll have wires showing unless you're really good at tucking them under the trim.
- Budget-wise, $200-$400 is the sweet spot. Don't go cheaper or the app will be trash and the colors won't match the Audi MMI.

I'd say go with a specialized Audi-fit kit from a reputable site rather than a random Amazon brand. It'll save you from rattles later! gl!

yo, congrats on the Q4! i totally feel u on the interior... the base white LEDs are kinda boring for an audi. before u dive in, basically how these aftermarket kits work is by using ultra-thin acrylic strips that jam into the gaps of ur trim. i actually did a similar project on my car recently. honestly, the hardest part is the door wiring. i chose to tap into the window switch power cuz running wires through the door accordion boot to the main cabin is a HUGE pain. my current setup cost me about $250 and looks pretty OEM during the day since the strips are blacked out when off. i mean, it wont sync with the MMI (thats super rare for aftermarket), but the app control is actually decent for picking colors. just be careful with the floating console—it's got some tight angles so you gotta be patient. good luck!!
