The engine code is also stamped on the cylinder block behind the oil filter.

There is also a sticker glued to the timing chain cover with the "engine code" and "serial number".

The first three digits describe the mechanical structure of the engine and are stamped on the engine. The fourth letter describes the engine torque and output and is dependent on the engine control module. The four-digit engine code is located on the type label and the vehicle data label. It can also be read via the engine control module.
