Whats the latest IM version

I’ve been working on my (new to me) 2007 S8, it was noted on the Audi service records that the IM has failed on my car, but had not been replaced by Audi as the previous owner had gone and had the repair at an independent shop.

Below is the part fitted to me car part # 07L.133.185.M, with what looks like a Nov 16 build date.

Sorry for the side on photo, for some reason it auto rotates it.

Can anyone confirm if this is the latest greatest version?, anyone know if this version still have issues or not?

Cheers

Ross
