Glad this adds more info on the auxiliary fan, since US cars had a/c we would not have known that it was used on all automatic coupes as well.
Fixing that little rust spot...

My 1970 2800CS appears to be a US model that never had a/c and no aux fan, but was, according to BMW, "delivered to a company named J.B.S. in Frankfurt/Main, probably for delivery to a US citizen temporarily living in Germany."
Did all US delivery cars have a/c?
I believe Hoffman ordered all with a/c but yours ordered in Germany would be different. Canada got the same VIN series as us and those cars could come without a/c and usually had vinyl seats.
Yes, my Chamonix car has blue vinyl seats as well. They are still in terrific condition.
Was busy with the subframe; it was covered in 40 years of wax oil and dirt, so started by scrapping it off as best I could.
While cleaning the remains with solvent, I noticed how annoying all the weldspatter bits are; there were about 100 little blobs scattered all over the part, from factory it seems.
But they are bloody annoying if I ever want to wipe-clean the subframe ever again. So I belt sanded them all off.
Not sure if it will ever earn those 3 hours back, ever....
Then I also noticed cracks, the famous ones nearbthe towhook, so I had it sandblasted to see if there were more. (None luckily!)
Drilled the endof the crack, grooved it, and welded them up, then checked with dye penetrant. My welds were good, but it's not easy to check as the dye just hides in the 1000 corners, dimples and ridges that are on and around the welds. Rest of the frame checked out fine.
But what a sh*t job did my new sandblast shop do! I was hoping it would be clean enough to send it out for rustpreventative coating, but still a cup full of grease and sand and stones were stuck in corners.
I'm sending it back for a rerun, let's see if the get the PINK clue...
