From 2001 to 2006, the Volkswagen BCB 16v 1.6-liter injection engine was manufactured and fitted to the Golf 4 model as well as similar models like the Bora, Seat Toledo, or Leon. With an upgraded exhaust system, this power unit is basically an analog of the AZD engine.

ABU, AEE, AUS, AZD, BCB, BTS, CFNA, and CFNB are all part of the EA111-1.6 series.

Disadvantages of the VW BCB engine
The throttle or EGR valve is typically contaminated by floating engine speed.
Pipes, a thermostat, and the cooling system frequently have leaks.
Timing belt replacement is highly costly, and the valves always bend when it breaks.
Lambda probes, coolant temperature sensors, and ignition coils are also well-known for their poor dependability.
