This post offers two solutions to the problem that Foxwell NT520 scanner unable to register (it states the s/n is not valid) and download the BMW software. I need the scanner to diagnose me electric water pump problems (separate thread).
Solution 1:
The website doesn’t want the SN on the back of the scanner; it wants the SN when you power on the scanner under settings.

Solution 2:
Some people prefer to get one foxwell nt520 loaded with BMW software .

For old BMW with 20pin port, you need one 20pin cable.
Feedback:
It is quick, slick and reliably.
I have used it on my e46 and my e90. The screens are intuitive and it feels well built. I don’t know if it is a shop quality tool in terms of endurance but it sure seems a perfect weekend warrior tool.
Added bonus, my seller was $159 free shipped. The scanner was registered to the vendor but he left a number to message to request it be reset. My account works and my scanner is registered in my name now.
I will likely add the Audi software next and use it on my B8 A4.
