Hey there, just had an F55 here at my shop with the same issue. Remove the shift lever assembly, the whole thing, not just the lever.
Carefully open it up. Inside there is a white lever that has a magnet on the back side of it (rear most) and the shift interlock solenoid pushes this lever.
On the one here, we removed that while lever and found the spring broken so that interlock lever's magnet was no longer in range of the sensor. We unwound the spring to get the length we needed and it works.
Hope it helps
Troy

Hello Troy. Is this removal done all from the top? I don't need a complete walkthrough, but just a general idea of how you got that seperated out would be greatly appreciated. Got this message on my F55 and would like to check out that lever before spending on parts or service. Thx.

Here is a picture of the actual spring. I unbent one turn to allow it to do it's job again.

Uopu can see the end that broke, it's sharp

Ahh, I understand the problem completely. I was asking about the whole assembly itself. Does it all come off via the top in the cabin? Thank you so much for this.

Okay. Finally getting back to this. When did I first post - a year ago. Well, I guess that a "Secure Vehicle From Rolling" message wasn't enough to make me hurry. Anywho...

Finally did it. Let me thank everyone here and elsewhere for helping. I couldn't have done it this easily without all the participation in the string.

So here's what I got.

• Model F55 - 2016 Cooper S 4 door
• I bought the spring on Ebay. Between the good packaging, and the helpful diagram and that it definitely feels like an upgrade... I have no regrets in paying $25 for it.
• Followed instruction here for the sping itself.
• Followed this step by step for getting the shifter out (it's f56 instead of f55) but everything was the same. step by step Stop when they start taking the shifter apart in the car. You want to take the whole thing out and bench disassemble it.

My notes for anyone following in the footsteps.

• In the disassembly, it says to pull the shift knob before seperating the shift boot and disconnecting the wires. I say reverse those steps. When I pulled the shift knob it came flying off and pulled the boot and yanked the wiring connectors apart. I was lucky nothing was broken. But if you disconnect the 2 wiring connections first, then you have nothing to fear.
• Pay attention disassembling the shifter. Most so on the park release button connected to the 2 red wires. It was tough to figure out how that went back together.
• And have fun and enjoy the silence when you shut down and it's not beeping at you!

I have the same error code in my 2015 with F55 engine and 25K miles on vehicle. Dealer wants $1600 to repair. Car runs fine. What is the downside of not repairing? Can't you simply apply hand brake to prevent car from rolling while parked?

If it's the little spring sensor problem causing it, then it's really mechanically in park anyway. Will it roll on a grad when in park? I'm betting it wont. It's just an annoying error message. Won't look good for you when going to sell it. But otherwise no.
