VW submits 2.0L emissions refit proposal; Audi to handle 3.0L fix | LeftLaneNews

W met with the agencies last week to discuss the tentative plan to bring the 2.0-liter TDI engines into compliance with government emissions regulations, however the company is not yet publicly disclosing specific details, according to Edmunds.

The company is expected to implement expensive hardware modifications in some of the vehicles outfitted with the offending four-cylinder engine. Most lack a urea-injection system to help minimize nitrogen oxide output.


Audi believes the 3.0 sedans and SUVs can be fixed with new software.
