VW/Audi 1.2 TDI CR EA189 Engine
There are many VW/Audi 2.0 TDI options available starting in 2003. The 2.0 TDI engine replaces the infamous 1.9 TDI engine. It is more reliable, but it is also considered to be more modern.
In 2003, the Volkswagen Group created the EA188 2.0 TDI PD (or “Pumpe Dause”) direct injection engine with a Garett turbo.
The engine produced 140hp up to 170hp and 236 lbft to 258 lb-ft torque. In late 2007, the Volkswagen Group introduced the EA189 2.0 TDI CR (or “Common Rail”) direct injection engine. It produced 140 HP and 236 lb. ft of torque.
The Volkswagen enthusiasts reading this will know that the EA189 engine was the heart of the notorious “VW Emissions Scandal.” Volkswagen allegedly installed “defeat mechanisms” in the EA189 to evade emissions testing.
Volkswagen had to inform all EA189 2.0 TDI vehicle owners about the buyback program as part of a $14.7 million settlement. The Volkswagen Group released the EA288 2.0 TDI after the scandal in 2015.
It is used in both VW and Audi vehicles. The EA288 can produce 74hp to 236hp and 166 lbft to 369lbft of torque.
