1985 525i......when it's hot it can crank over and over before spluttering to a start or not start at all......second try it fires immediately.

I've found that spraying silicon lube into the air flow metre cures this for a short time until it needs done again, i presume that this is the cause in this particular case.

I don't think I'd spay silicon into the AFM. That migh gum it up. I'd detatch the intake boot and clean the throttle plate and body with carb cleaner. I'd do the same with the AFM to get all that silicon out.
