Service campaign Circular 93PG_REV2

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

The document

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.

Vehicles listed
AUDI E-TRON2022, 2023
AUDI E-TRON2024
AUDI E-TRON SPORTBACK2022
AUDI E-TRON SPORTBACK2023 (the catalog's model; the bulletin names a series or trim of it)
AUDI E-TRON SPORTBACK2024

Listing a model year does not mean every vehicle of it is concerned: the document says which.
