Hi, can anyone tell me where i will find the engine serial number on Audi S5 3.0 TFSI?

The only place you will be able to see it is on the white plastic printed sticker on the front cover plate and it will start CAK (for CAKA) or CGW (for CGWC) and then there will be a six digit number. You can also find this on your registration document.
