Audi A4 Bulb Size By Years

This bulb size chart lists the common replacement bulbs for a 2011 Audi A4 and explains what each socket uses. Think of it as a baseline reference to avoid buying the wrong part. I write it from service experience, so it may highlight common fit issues and compatibility notes you won't see on generic lists. In some cases, trim levels and aftermarket kits change the required bulb or adapter. Check for variations like xenon modules, LED conversions, or optional parking lights. Detection is simple: compare your current bulb, part number, and harness before ordering. Mitigation can mean bringing a photo to the store or ordering a compatible adapter. Safe defaults are OEM-equivalent bulbs and checking polarity for LEDs. Quick checklist: confirm model year, inspect the old bulb, verify socket type, and keep the receipt.
