The 2.0-liter Volkswagen CBAB 2.0 TDI diesel engine was produced from 2007 to 2015 and was installed in many of the company’s popular models, such as the Tiguan, Golf 6 and Passat B6. This diesel is very popular.
In 2007, Volkswagen introduced a new family of Common Rail EA189 diesel engines, one of the representatives of which is a 2.0-liter power unit under the CBAB index. By design, there is a cast-iron block, an aluminum 16-valve cylinder head with hydraulic lifters, a timing belt, a fuel system with a Bosch CP4 single-plunger pump and piezo injectors. The KKK BV43 turbocharger with a variable geometry vacuum drive is responsible for supercharging.
In addition, this diesel engine is equipped with an intake manifold with swirl flaps, an electrically actuated EGR valve and a balancer block combined with an oil pump.
EA189 family: CAYC, CAAC, CAGA, CAHA, CBAB, CFCA, CFGB, CLCA, CLJA, CKTB, CFHC, CKUB, CDCA, CNEA, CNFA, CNFB, CSHA.

Disadvantages of the VW CBAB engine
- This power unit is equipped with a block of balancers, combined with an oil pump, which is driven by a hex key that is too short. It turns off up to 150,000 km, which turns off the oil pump and lowers the lubrication pressure in the system. In November 2009, the length of the ill-fated hexagon was increased and this problem was gone.
- The Bosch CP4 fuel system is considered very reliable, but it also has weaknesses: if not properly maintained, the fuel pump pusher roller turns across the cam and the pump starts to drive chips. Also, the fuel pressure regulator regularly wedges here, and the use of low-quality diesel fuel immediately affects the resource of the piezo injectors.
- The KKK BV43 turbine, also known as the BorgWarner, is not a problem, it is let down by a vacuum geometry change actuator in which the membrane cracks. Sometimes the turbine control valve itself fails or its vacuum tube bursts.
- As in any modern diesel engine, contamination of the EGR valve and intake manifold swirl flaps, which also have a not particularly reliable mechanism, cause a lot of trouble. You also have to regularly update the oil separator membrane in the valve cover.
