Although admittedly biased in this regard....! I must agree with my esteemed co-author. The information on the web site is quite confused/ confusing. We stuck with Engelen as the gold standard.
One thing we have found quite confusing is trying to tie some changes to VIN. The engine type changes are among them. We hope to put something together on that in a future issue. There are just too many small changes on the engine, and it gets really confused when looking at USA versus rest-of-world.
