A series of Volkswagen EA189 1.6 and 2.0 TDI diesel engines was produced from 2007 to 2015 and was installed on almost the entire model range of the German company, including Audi cars. Formally, this family also included the 1.2 TDI engine.
EA189 diesels debuted in 2007, first with 2.0-litres, and two years later with 1.6-litres. These engines differed from the predecessors of the EA188 series primarily in the fuel system: pump injectors gave way to Continental's Common Rail with support for Euro 5 environmental standards. The intake manifold received swirl flaps, plus the exhaust cleaning system became more complicated.
In all other respects, the changes in these engines were more evolutionary than revolutionary, because these are almost the same diesel engines with an in-line 4-cylinder block made of cast iron, an aluminum 16-valve block head, a timing belt drive and hydraulic compensators. Supercharging is handled by a BorgWarner BV39F-0136 variable geometry turbocharger.
There were many modifications of 1.6-liter engines, we will list the most common of them:
The 2.0-liter engines did not differ much from the 1.6-liter ones, except for the displacement, of course. It used its own more efficient turbocharger, most often the BorgWarner BV43, as well as some especially powerful diesel modifications equipped with a block of balancer shafts.
Separately, it is worth talking about the updated diesel engines, sometimes they are called the second generation. They finally got rid of the constantly jamming intake manifold swirl flaps, and also replaced the capricious piezo injectors with more reliable and simple electromagnetic ones.
