The only thing I can think of right off the top of my head is that the EGRVPS is more commonly referred to as EVP. Otherwise, quite an exhaustive list you've put together.

Actually, there seems to be new ones born every day...... toss in the special requirements for diesel and turbocarged applications, it can be hard to keep up.
