Will the 1 of 2 ever-made Santorini blue 850CSi finally have working AHK? This ultra-rare V12 E31 features a marvel of '90s engineering: rear-wheel steering (AHK). BMW has long discounted any support or parts supply for this system. Over the last several videos, I've been trying to get this system working again, and this episode is the culmination of previous work.

We are rejuvenating this rare '90s BMW 850CSi finished in Santorini blue, and it's been a battle every step of the way. The rear wheel steering, aka AHK, for which the parts are obsolete, is broken, and we need to fix it, whichever way possible. We dive deeper into the AHK system, but more problems crop up along the way.

I faced a vicious '90s product on this rare V12 BMW E31 850CSi 6-speed. This car is a gem, and an ultra-rare find with only 2 examples made in this spec: Santorini blue exterior, black leather interior. It's neglected and broken, and I attempted to revive the '90s high tech called AHK, aka rear wheel steering.

We are rejuvenating 1 of 2 ever-made BMW E31 850CSi finished in individual Santorini blue over black leather interior, and run into an issue that appears impossible to solve. An obsolete part made by a company that no longer exists.

I found 1 of 2 ever made BMW E31 850CSi finished in individual Santorini blue over black leather interior. It's broken, it's neglected, it's beautiful! The CSi is powered by the S70 V12 engine built by BMW Motorsport, pumping out 380 hp. Despite its low mileage of 73k miles, this rare machine needs a lot of work, and in this episode, we go over the entire condition of the car and start wrenching!
