Awesome! Any pics?Just did this retrofit on a 2018 2.0t 8A Luxury. Works fine, no problems or issues (other than me being dumb and managing to lock myself out of the car in the process, with the coax cable connectors - apparently for the Antennae - disconnected from the body harness connector block. Then, after getting the drivers door open using the physical Key, having the alarm go off with no way to shut That off.. Lesson learned - disconnect the battery before doing this..). Thanks for all of those who posted instructions and photographs, it made the "figuring out" part of the job easy.
For anyone who is on the fence about doing this - it's easy, if you have ever turned any kind of a wrench, and simple enough to "undo" if there was ever a reason, such as a warranty issue. It is Not necessary to acquire the right terminal connector for the BCM harness block - simply tinning the end of a wire and inserting it works fine. Splicing the other end at the main body harness connector is not difficult either. I went ahead and Soldered mine, to be certain of the connection, but simply splicing it should be fine as well.
The physical process of installing the new Wheel (with paddles) is also not difficult. In fact, with no need for a wheel Puller, it's about as simple as you could ask for. Do be careful with the Torx bolt that holds the wheel on there, though - do Not strip out that torx. It's a fairly soft material that is used for that bolt - it Can be ruined if you are not paying attention, and then getting the wheel off will be Much more "challenging". I know, I did that to the new/used wheel that I bought, which came as part of a column assembly still all bolted together. I destroyed that bolt and then had to chisel it loose to get the wheel off the column. I was a Lot more careful when taking the wheel out of the Car, believe me
If not I guess need to take my wheel off
Yes, that is All the wiring that is needed to make shift paddles work, connecting those two terminals. The harness connectors up under the wheel itself already have the correct stuff in them, nothing else has to be changed.So to wire this, all you need to do is connect terminal 88 on the x275 to terminal 21 at the X3?
And if the terminals have wires in the connectors, just tap them to make terminal 88 and 21 connected?
Do you need a new clock spring if you want the heated feature?
Seems like the hardest part is accessing the wires.
(Mine is a 2017, if that makes any difference.)
