Audi Engine ID Codes
 

I have been trying to sort out the bewildering array of engines codes for Audi's 4 cyl power plants. Let's see if I've got this right:

The 1.8T 180hp were ATC and AWP with the AWP getting the early VVT.
The 1.8T 225hp TT was an AMU, with later years getting the BEA or is it the BAM?.
The 1.8T 265hp TTS still has the EA113, so all TTS's still have a timing belt.
The 2.0T 200hp in 2008 & 09 was the CCZA and the first 4 cyl with a timing chain
The 2.0T 211hp the newest 4 cyl is the EA888 with Variable lift cam and timing chain.

Any corrections or other input?

The reason I wanted to sort this out is to determine which engines have the timing chain. It does however, also show a nice progression in engine development by Audi
