## 1.6l TDI engine with 4-valve technology

The 1.6l TDI engine with 4-valve technology is based on the 2.0l 103kW TDI engine with common rail injection system. The engine comes in three power versions — 55kW, 66kW and 77kW. Thanks to continued further development of tried and tested technology and the new common rail injection system from Continental (PCR 2), these engines fulfil the EU5 emissions standard. The engine is used in the Polo, Golf and Passat.
