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

The 1.9-liter Volkswagen AXB 1.9 TDI diesel engine was produced from 2003 to 2009 and was installed on the popular Caravelle and Transporter T5 minibuses. Such a diesel engine has become quite widespread.
The 1.9-liter 8-valve VW AXC 1.9 TDI diesel engine was assembled from 2003 to 2009 and installed on various modifications of the popular T5 Transporter minibus. This diesel engine was the weakest in the line and endowed the car with mediocre dynamics.
The 2.0-liter 8-valve Volkswagen BMM 2.0 TDI engine was produced from 2004 to 2010 and was installed on many models of the concern with a transverse power unit. This diesel engine is known for its whimsical piezoelectric unit injectors.
The 2.0-liter Volkswagen BMP 2.0 TDI diesel engine was produced from 2005 to 2010 and was installed on the sixth generation of the popular Passat model and the similar Skoda Superb 2. This diesel engine is known for a frequent problem with the rapid wear of the oil pump hexagon.
The 2.0-liter Audi BPW 2.0 TDI diesel engine was assembled by the company from 2004 to 2009 and was installed only on the very popular A4 model in the B7 body. The most famous problem with this motor was the rapid wear of the hexagon of the oil pump.

The 2.0-liter Volkswagen BKD 2.0 TDI diesel engine was produced from 2003 to 2011 and was installed on a number of models of the German company with a transverse power unit. Such a diesel engine did not have balance shafts and avoided problems with the hexagon of the oil pump.
The 2.0-liter Volkswagen BKP 2.0 TDI engine was produced by the concern from 2005 to 2008 and was installed on a rather popular Passat model in the B6 body. This diesel engine stood out among analogues with piezoelectric unit injectors.
The 2.0-liter Volkswagen BMR 2.0 TDI engine was produced by the company from 2005 to 2008 and was installed only on the sixth generation of the popular Passat model. This diesel engine is known for its whimsical piezoelectric unit injectors.
