Bought all components brand new when flashing my ECU and transmission.
I went with bimmer-connect.com cable to ensure that my flashes always worked. Im sure the amazon stuff works too but I wanted to play it safe.
This combo works with your macbook and iphone - Everything you need for Bootmod3 and xHP flashtool.
$50 picked up
$60 shipped
Works only for an F30 or F series vehicle. Sold the F30 and no longer need this stuff.
