Query: Don't Bother !

This review echoes the words of Cliff Hunt of Indiana. Unless you're trapped in the Arctic tundra and need to know how to change your oil, don't bother with this book. A common problem with MB diesels is smoke coming from the exhaust pipe and this book doesn't even mention that.I bought mine from an auto parts dealer, wrapped in plastic and unreturnable of course, and realized perusing it in the parking lot I had wasted my money.
