Customer Only (Retail Sold) USA ONLY - 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 extent of the emissions increase under off-cycle conditions depends upon how the vehicles are driven. Updated work instructions.
