In 2015 VW updated all their 4-cylinder TDIs with completely new engines. The new engines are part of the “EA288” family, but the specific engine codes may be different by model. The engine code will determine which fuel and air filters the car requires, though the oil filters are the same for all 2.0L EA288 family engine in the USA.
Here are the engine codes we know so far.
2015+ Golf TDI – CRUA
2015+ Golf Wagon TDI – CRUA
2015+ Jetta TDI – CVCA
2015+ Passat TDI – CVCA
2015+ Beetle TDI – CVCA
