# Service bulletin 23T4 Customer Le

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.

- Published by NHTSA: 2017\-10\-15

## NHTSA's summary

The Environmental Protection Agency and California Air Resources Board have determined that Audi A3 vehicles equipped with a 2.0L 4\-cylinder TDI engine do not comply with applicable emissions regulations. The emissions control systems on the vehicles will not control emissions under off\-cycle conditions as effectively as during the federal test procedure. The extent of the emissions increase under off\-cycle conditions depends upon how the vehicles are driven.
