2017-2026 Audi Q7/SQ7 Cowl / Firewall Cover Grille 4M1819154A

This used OEM Audi cowl / firewall cover grille (part number 4M1819154A) sits across the base of the windshield on Q7 and SQ7 models. Also called the cowl grille or firewall cover, it seals the area between the hood and windshield, directing air into the cabin intake while blocking debris from the wiper linkage and cowl drains. Fits vehicles with 2.0L turbo, 3.0L supercharged, 3.0L diesel, and 4.0L twin-turbo engines. A cracked or missing grille allows leaves and water into the ventilation system, potentially damaging the blower motor or cabin filter—this used piece restores that critical seal.
