Look at the coolant lines closely to see if you can see the 11 digit part nbrs written on the hose(s). Then see if they appear in the part databases if you do a search.
part nbrs should be in this format “
xx xx x xxx xxx”…there are no hyphens…so if you see a dash and extra numbers at the end…drop them in your search xx xx x xxx xxx
-xx
Sometimes only the last 7 digits are written on the part…in this case look for
x xxx xxx…and again, if there’s any additional numbers after a hypen or period…drop them and only use the front 7 digits.
EDIT…since the Alpina B7 is a take-off of the N63/N63TU…perhaps if you pull up the diagram for the charge air coolers using the N63/N63TU (not sure which engine knock off you have)…it could lead you to the correct hoses.
This diagram shows the lines connected to the charge air coolers…from this diagram…if you go to the charge air cooler diagrams for the N63 or N63TU diagrams in the F01…you can see the lines connected and the part nbrs in the database:
