Below is a table of the most common 1.8T 20v engine codes: If you prefer, you can also view a chart of engine codes here
The engine code can be found stamped on the front of the cylinder head close to the camshaft position sensor. Please note that the longitudinally mounted engines require many modifcations to fit and are generally best avoided for transverse applications. The only exception is the Mk1 see here
