U.S.A.: 2010-2013 MY Audi A3 2.0L TDI (Generation 1)
Check Campaigns/Actions screen in Elsa on the day of repair to verify that a VIN qualifies for repair under this
action. Elsa is the only valid campaign inquiry & verification source.


Campaign status must show “open.”



If Elsa shows other open action(s), inform your customer so that the work can also be completed at
the same time the vehicle is in the workshop for this campaign.

Problem Description

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.

Corrective Action

Install updated emissions control system parts and software, install a TDI Emissions
Modification – Proof of Completion Label and install a Supplemental Vehicle Emissions Control
Information Label.
At this time, affected new and used vehicles in dealer inventory are not included in this
emissions modification release.
If the vehicle has been modified by the customer prior to receiving the emissions modification
in a manner that may yield a non-compliant emissions system (for example, removal of a
catalyst, installation of parts that impact emissions or emissions-related parts, or modifications
to the ECU or computer software of the vehicle), Audi may not be able to perform the emissions
modification until the customer corrects such modification.
