VW CDAB engine

1.8-liter turbocharged Volkswagen CDAB 1.8 TSI engine was installed from 2009 to 2018 and was used exclusively in models of the German group intended for emerging markets. This powertrain differs from the analogous CDAA engine with different Euro 4 compliant software. The EA888 gen2 lineup also includes: CDAA, CDHA, and CDHB.

Engine Overview and Common Failures

According to the catalog, the weight of the CDAB engine is 144 kg. The CDAB engine number is located at the junction with the gearbox. The use of a lightweight connecting rod and piston assembly and poorly designed rings led to the engine consuming oil from the start, with increased consumption over time. The manufacturer constantly released new pistons: the AF series was replaced by BM, and then BN, but the high oil consumption issue could not be completely resolved until the end of production. Many people solved the problem by purchasing pistons from alternative manufacturers. High oil consumption results in rapid carbon buildup inside the engine. Carbon deposits particularly affect the valves and throttle in the intake system, causing unstable engine operation. Another common issue is the timing chain jumping due to its limited lifespan and tendency to stretch, often resulting in sixteen bent valves. The hydraulic tensioner is another weak point in the camshaft drive mechanism. The smell of gasoline on the dipstick is often an indication of a faulty expensive fuel injection pump (TNVD) in vehicles with this engine. Additionally, ignition coils, the oil pump, and the water pump have relatively low durability. The crankcase ventilation system tends to get clogged quickly, leading to oil leaks.
