EA898 or Audi V8 TDI engines

Diesel engines of the EA898 or Audi V8 TDI range were first introduced in 1999 and have since been installed on the flagship models of the German concern, such as the A8 sedans. This family also usually includes a 12-cylinder diesel engine, which was installed on the Q7 crossover.

Diesel engine 3.3 TDI

In 2000, a V-shaped 8-cylinder diesel unit appeared on the restyled A8 D2. This engine had a cast iron block, two aluminum DOHC cylinder heads with hydraulic lifters, a timing belt drive and a pair of Garrett variable geometry turbochargers with an intercooler. Also, this engine was equipped with a Common Rail fuel system manufactured by Bosch.

In the first line there was one power unit with a volume of 3.3 liters and it was produced for only two years.

3.3 TDI:

• AKF (225 hp / 480 Nm) for Audi A8 D2.

Diesel engines 4.0 and 4.2 TDI

In 2003, a 4.0-liter V-shaped 8-cylinder diesel debuted on the Audi A8 D3. Its main difference was the timing chain drive and intake manifold with swirl flaps. However, this engine was produced for only two years and gave way to an updated 4.2-liter engine. In addition to increasing the working volume, the manufacturer upgraded the problematic timing chain, installed a new Bosch Common Rail fuel system with piezo injectors and other turbines.

We know of one 4.0-liter engine and seven different 4.2-liter powertrains.

4.0 TDI:

• ASE (275 HP / 650 Nm) for the Audi A8 D3.

4.2 TDI:

• BMC (320 HP / 650 Nm) for Audi A8 D3;
• BVN (326 hp / 650 Nm) for Audi A8 D3;
• CDSB (351 hp / 800 Nm) for Audi A8 D4;
• CTEC (385 hp / 850 Nm) for Audi A8 D4;
• BTR (326 hp / 760 Nm) for Audi Q7 4L;
• CCFA (340 HP / 800 Nm) for Audi Q7 4L;
• CKDA (340 HP / 800 Nm) for VW Touareg 2.

In addition to the Volkswagen and Audi models, this engine was installed on the Porsche Cayenne under the MCU.DB index, and in a special modification with twin turbocharging, which developed 382 hp and 850 Nm.

Diesel engine V12 TDI

The 6.0-liter diesel engine was created for the Audi R10 TDI racing car for the 2006-2008 seasons, but after the end of its sports career, it was installed on the Audi Q7 crossover for several years. This motor has little in common with the V8 TDI, since it has a camber angle of 60° instead of 90°, however, in a number of sources, for some reason, it is referred to this particular line of power units. It also has an unusual timing chain drive with an intermediate shaft, a couple of powerful turbines and a particularly efficient Common Rail fuel system from Bosch with a pressure of up to 2000 bar.

There was only one modification of this engine with a capacity of 500 hp and 1000 Nm.

6.0 TDI:

• CCGA (500 HP / 1000 Nm) for Audi Q7 4L.
