EA288 or VW 1.6/2.0 TDI engines

The line of VW EA288 1.6 and 2.0 TDI diesel engines was first introduced in 2012 and at that moment almost completely replaced its predecessors on the group’s models. Formally, this family also included 1.4 TDI diesels.

Diesel engines EA288 1.6 TDI

In 2012, new diesel engines were introduced to replace the power units of the EA189 family. Structurally, they were very similar to their predecessors, here the same cast-iron block and a 16-valve aluminum cylinder head with hydraulic lifters, the same timing belt drive and a variable geometry turbine, which is here made integral with the exhaust manifold. There were again two main working volumes: engines of 1.6 liters or 2.0 liters were offered.

However, the new diesel powertrains received some rather serious differences. First of all, expensive capricious piezo injectors have given way to simple electromagnetic ones, and an oil pump with adjustable output is combined in one housing with a vacuum one. The rest of the innovations were mainly related to ecology, a number of versions already supported Euro 6.

There were a lot of engine modifications:

• CLHA (105 hp / 250 Nm) for Golf 7, Octavia 3;
• CLHB (90 hp / 230 Nm) for Golf 7, Octavia 3;
• CRKA (90 hp / 230 Nm) for Golf 7;
• CRKB (110 hp / 250 Nm) for Audi A3 8V, Golf 7;
• CXXB (110 hp / 250 Nm) for Seat Leon 3, Golf 7;
• DBKA (110 hp / 250 Nm) for Audi A3 8V, Octavia 3;
• DDYA (115 hp / 250 Nm) for Audi A3 8V, Octavia 3;
• DCXA (120 hp / 250 Nm) for Passat B8, Superb 3;

Diesel engines EA288 2.0 TDI

2-liter diesel engines did not differ from their younger counterparts in anything other than the working volume. The only thing is that their most powerful modifications were equipped with a block of balancing shafts.

There were a great many versions of them:

• CKFC (150 hp / 320 Nm) for Octavia 3;
• CRLB (150 hp / 340 Nm) for Audi A3 8V, Passat B8;
• CRMB (150 hp / 320 Nm) for Octavia 3, Golf 7;
• CUWA (184 hp / 380 Nm) for Audi Q3 8U;
• DEUA (150 hp / 320 Nm) for Audi A4 B9, A5 F5;
• DETA (190 hp / 400 Nm) for Audi A4 B9, Q5 FY;
• DBGC (150 hp / 340 Nm) for Tiguan 2, Kodiaq 1;
• DFGA (150 hp / 340 Nm) for Tiguan 2, Kodiaq 1;

Diesel engines EA288 EVO

In 2018, the company showed an updated line of diesel engines of the EA288 family. Firstly, the new units switched to an aluminum cylinder block with steel liners. Secondly, the vacuum and oil pumps were separated again, the experiment was declared unsuccessful. Thirdly, the turbocharger was placed closer to the first cylinder to improve the environment.

Also, the line of updated power units was divided into two different families: economical with small steel pistons, productive with large aluminum ones.

These motors have only recently begun to be installed:

• DEZB (136 hp / 320 Nm) for Audi A4 B9;
• DEZD (163 hp / 380 Nm) for Audi A6 C8;
• DFBA (204 hp / 400 Nm) for Audi A6 C8, A7 C8;
• DFHA (190 hp / 400 Nm) for Audi Q3 F3;
