Engine Number/Engine Characteristics

WARNING: This page is about a different car, the 2012 Audi Q5, 2011 Audi Q5, 2010 Audi Q5, and 2009 Audi Q5. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

The engine number is only visible if the front engine cover is removed.

The engine number ("engine code" and "serial number") is located at front on cylinder block at top -arrow 1-.
Engine codes beginning with "C" are four-digit.
The first three digits of the engine code stand for displacement and the mechanical structure of the engine. They are stamped in the cylinder block, including the serial number.
The 4th digit describes the engine output and torque and depends on the engine control module.

NOTE:

Ignore -arrow 2-.

The four digit engine code is on the type plate, vehicle data label and engine control module.
