EA188 or VW 1.9/2.0 TDI engines

The family of Volkswagen EA188 1.9 and 2.0 TDI diesel engines was assembled from 1996 to 2010 and was installed both on the entire model range of the VW concern and on cars from other manufacturers. Formally, this family included diesel engines 1.2 TDI and 1.4 TDI.

Diesel engines EA188 1.9 TDI

Diesel engines with pump injectors appeared in 1996, but they began to be installed two years later. From the predecessors of the EA180 series, the new engines differed not only in the injection system, but also in the absence of an intermediate shaft, the oil pump rotated in a separate chain from the crankshaft. Other notable differences here were: a vertically located fuel filter, a vacuum pump drive from a camshaft, a cooling system pump built into the engine block.

1.9-liter power units existed only in an eight-valve version, where a single camshaft was rotated by a seriously reinforced timing belt with a hydraulic tensioner. According to the old tradition of the VW concern, there were hydraulic lifters in the aluminum cylinder head. Also, powerful modifications already had modern turbines with variable geometry.

In total, about 30 versions of such diesel engines are known, we list only the most popular of them:

• AJM (115 hp / 285 Nm);
• AWX (130 hp / 285 Nm);
• AVF (130 hp / 310 Nm);
• AUY (115 hp / 310 Nm);
• ASZ (130 hp / 310 Nm);
• AVB (101 hp / 250 Nm);
• BKC (105 hp / 250 Nm);
• BXE (105 hp / 250 Nm);
• BLS (105 hp / 250 Nm);
• AXB (105 hp / 250 Nm);
• AXC (86 hp / 200 Nm).

Diesel engines EA188 2.0 TDI

In 2003, the line of EA188 diesel engines expanded with 2.0-liter diesel engines, which, unlike younger brothers, existed in both 8 and 16-valve versions. Also, the two-liter unit received an easy start system in the form of glow plugs, a switchable intercooler and a rotation sensor built directly into the crankshaft oil seal housing.

It is worth recalling the updated engines of the last years of production, they are sometimes called EVO. The main difference was the latest pump injectors with a piezoelectric valve, but many servicemen advise avoiding these power units in the secondary market.

We know of 19 modifications of such diesel engines, but here we list only the most popular:

• BMM (140 hp / 320 Nm);
• BMP (140 hp / 320 Nm);
• BPW (140 hp / 320 Nm);
• BRT (140 hp / 310 Nm);
• BKD (140 hp / 320 Nm);
• BKP (140 hp / 320 Nm);
• BMR (170 hp / 350 Nm);
• BRE (140 hp / 320 Nm).

Since 2007, such diesel engines have begun to be replaced by EA189 series engines with a Common Rail system.
