Decision: this bulb size chart exists to help you identify the correct replacement bulbs for a 2020 Audi A4 allroad, minimizing trial-and-error and warranty concerns. Constraints include model variations and trim-dependent options, which create ambiguity; the list therefore focuses on the most commonly documented configurations and notes limitations where applicable. Options presented show standard, high-performance, and LED equivalents so you can compare fitment, brightness, and compatibility before purchase.
