M Driver's Package after the fact

So I really want to unlock that extra 35 KPH at the top end, but I didn't spec it from the factory.

Are dealers authorized to "update" the software package on my car to increase the limiter?

I've asked my dealership a couple of times and they have gone radio silent on me.

My understanding is you have to unlock and modify the ECU. So shipping it off to Fentmo is the only way. Of course doing that gets you more than 35 KPH.

It can be done but it is very cumbersome, at least in Spain. An acquaintance is doing it on his M4 and he has been trying for more than 9 months. Apparently the request has to be approved by BMW Spain that I imagine they will contact the headquarters in Germany. The car has to be 100% original and also has to bring the specifications that allow the M Driver's Package such as no sunroof, etc etc.
