Audi A6 Bulb Size By Years
Finding the correct bulb sizes for a 2018 Audi A6 can feel tedious when service manuals disagree. This list is meant to remove that confusion by showing recommended bulb types and locations, with compact notes on fitment constraints and common trade-offs like brightness versus heat. Use it as a practical reference, not a substitute for physical validation at the vehicle.
Assumption: your A6 uses stock housings and OEM sockets unless noted otherwise. Follow the recommended sizes, check part numbers, and validate fit before installing extras that generate more heat. I compiled this from hands-on maintenance and parts checks to keep it useful and reliable.
