I too have seen mistakes in the Motor Book.
IE: the Motor Book says my 2005 Mini Cooper S has an
Air Pump, when the ECS label on my Mini does NOT list an Air Pump.
The vehicle ECS label over rules the book!!
I need to make a list of mistakes and let the folks at Motor
Manual and maybe the BAR cops know of the SNAFU.
To CYA document the service order with the page/s
and which book you used.
We are not required to figure out which book is right
