What is a post TDI settlement Volkswagen?

To get up to speed real quick, back in 2015, the EPA issued VW a notice of violation for cheating on emissions tests. Making headlines across the world, named ‘Dieselgate‘.  Volkswagen bought back all of those affected turbo diesel vehicles (TDI’s) from customers or provided restitution to owners. These are now called a post-emissions modified Volkswagen.

What happened to the vehicles and how are they are fixed?

After Volkswagen bought the vehicles back, they came up with a fix. The official term is AEM (Approved Emissions Modification). This fix approved by CARB (California Air Resource Board) and the EPA (Environmental Protection Agency). Modifications include engine and transmission software updates as well as a new emissions system.

Some of the vehicles even qualify as certified. 


What does certified mean?

If the vehicle meets certain requirements, it is classed as part of the Volkswagen Certified Pre-Owned Program. Meaning there is additional warranty.

Certified vehicles come with a 2-year unlimited mileage comprehensive limited warranty for models 2011 and up. Special financing deals for CPO vehicles start with rates as low as 2.99% (for well-qualified customers). This, you will need to check with your VW dealership on for the details.

How do the modifications affect the cars?

What are the pros and cons of the modification and do they affect fuel economy and performance?

  • Engine sound may differ
  • Automatic transmissions will shift sooner at low acceleration in ‘Sport Mode’
  • DEF (diesel exhaust fluid) usage may increase
  • Smoother acceleration
  • Improved throttle response
  • Golf models with auto transmissions, shift pattern will adapt to high altitude (higher revs).
  • OBD (diagnostic system) emissions threshold adjusted

Volkswagen no longer manufacturers new diesel vehicles, so this could be an opportunity to swipe up a commuter that gets over 30 mpg.
