I bought a new X5 (F15) two months ago. The car is an "M" Sport with Dynamic Handling and Adaptive M suspension. The car was running fine until last week when the Idrive showed a "chassis function restricted" warning light. My understanding is the suspension in sport + driving mode is not working.
I took the car in to the dealer and they claim to have to order a module from Germany to replace a defective unit.
Has anyone had experience with this particular problem? I'm frustrated that I'm having problems with a car that was bought new two months ago, and equally worried that the mechanic will be chasing ghosts trying to figure out the real problem.
I love driving a BMW X5, but have had terrible experience with car reliability over the past 5 years. I traded in my 2010 X5 primarily because of maintenance issues. I got a brand new 2016 and it looks like I'm in for the same experience with getting my car to the shop.
