The crankcase or cylinder block is made of gravity-die-cast AlSiCu3 alloy for weight reduction. The new material allowed reducing the weight by 11 kg compared the previous 1.2 l TDI engine. It also almost 27 kg lighter than the 1.6 TDI. The engine has balancing shaft, which driven by a single speed 1:1 gear in the opposite direction to the crankshaft.

The increased displacement was achieved by increasing the stroke from 80.5 mm up to 95.5 mm (the same as the 2.0-liter four-cylinder TDI engine). The cylinder head has the same design as 4-cylinder MDB engines: four valves per cylinder, double overhead camshafts (DOHC).

The engine also has the water-cooled intercooler, catalyst converter, DFP, dual-circuit exhaust gas recirculation (high-pressure and low-pressure EGR) and the injection system called DFS 1.20 produced by Delphi.
