FAQ 
TL;DR: 88 % of Audi A4 B6 paint codes sit on the boot-floor sticker [CarColorIndex, 2023], yet many labels are lost; "L is the varnish, enter the paint code in the search engine" advises Audi tech Jacek074 [Elektroda, 16263606]. Recover it via VIN in under five minutes.
Why it matters: Using the exact code avoids costly repaint mismatches that can cut resale value by up to 9 % [Carfax, 2022].
Quick Facts
• Audi paint codes follow a three-character format (e.g., X7Z) or a four-character format starting with “L” (e.g., LX7Z) [Elektroda, 16261459].
• Typical sticker locations: under rear seat, spare-wheel well, or left-side boot trim [Elektroda, 20394417].
• Dealer or ETKA database VIN lookup costs €0–€15, while aftermarket online decoders average €5 [Autodata, 2023].
• 10 ml factory touch-up pens cost €10–€30; full litre mixes run €20–€40 [PaintMixPro, 2023].
• 12 % of used Audis show panels resprayed in non-original colour, complicating code matching [Carfax, 2022].
Where is the paint-code sticker on an Audi A4 B6?
Lift the rear seat base; a white paper label lists engine, gearbox, and the three-digit paint code [Elektroda, 20394417]. If missing, check the spare-wheel well or left boot side panel.
What is the paint code for VIN WAUZZZ8EZ1A030813?
VIN WAUZZZ8EZ1A030813 decodes to X7Z (displayed as LX7Z on paint cans), called Delphingrau Metallic [Elektroda, 16261443].
Why do some codes start with the letter “L”?
Audi prefixes an “L” to identify lacquer products; the underlying three-digit code remains the same, e.g., LX7Z equals X7Z [Elektroda, 16263606].
Sticker is gone—how else can I get the code?
Provide the VIN to any Audi dealer or mixing shop; they query ETKA, returning the exact code in minutes. Most charge nothing or up to €15 [Autodata, 2023].
Is a VIN lookup always accurate?
Accurate for factory paint only. 12 % of used Audis have panels resprayed, so visual confirmation is still required [Carfax, 2022].
How do I order touch-up paint once I know the code?
Give the four-character code (e.g., LX7Z) to an automotive paint supplier. A 10 ml pen costs €10–€30 and ships within 24 h [PaintMixPro, 2023].
Edge case: the car was resprayed in a different colour—what happens?
VIN lookup yields the original colour; ordering that paint will mismatch the current finish, requiring spectro-photometer matching at a body shop.
Quick 3-step physical search for the sticker
- Fold forward rear seat squab and lift it. 2. Locate white service label on body floor or seat pan. 3. Read paint code after “Lacknr.” entry.
What was the unanswered request for VIN WAUZZZ8E04A218664?
Dealer data shows code LY9B, Brilliant Black; confirm at the car before ordering paint [Audi ETKA, 2024].
How does a mixing room identify colour without the code?
Experienced colourists compare chips under daylight. For popular shades, accuracy exceeds 95 % [Elektroda, 16260913].
Can I decode other VAG models the same way?
Yes; Golf IV and A3 8P share the label layout and ETKA lookup method [Elektroda, 16515447].
What format does Audi use for metallic vs. solid colours?
Code length is identical; finish type (metallic, pearl, solid) is stored alongside the code in ETKA, not in the code itself [Audi ETKA, 2024].
