Vehicle-Specific Selection Notes
Fitment guidance for 4GD 807 521 A. Check production transitions carefully when the stated year sits near a facelift. Catalogue month ranges can be more reliable than a registration year alone. The completed check supports a traceable discussion between buyer and supplier.
The rear location on 2013-2015 AUDI A6L should be reviewed as follows: Review the application in the parts catalogue and then measure or photograph the removed panel. A facelift boundary or market-specific trim grade may require a different cover. The buyer can then connect the physical review to the supplier item record.
