Since I fitted the refurbed wheels to the X5 last week I’ve been getting a Run Flat error. And the Run Flat Reset fails when I do it.

Does anyone have any ideas what it might be? Are the sensors on the wheels that might need to be checked?

One thought that occurs is that the car they came off had aftermarket wheels. Would the owner have had to take the sensors off the original wheels and put them on his new ones?

Thanks
