Hey Daniel,
Welcome to the club
I don't want to discourage you but it took me about 5 months to figure out the exact parts I needed and find them on ebay. I hope I can help you bring that time down, but you have to be patient. I still haven't had everything installed and running on my car so I can't say my search is over (but fingers crossed)
BMW doesn't make it easy to retrofit optional extras on their cars.
Step 1: Get/find the VIN for your car.
http://vehicleidentificationnumber.c...in-number.html
Step 2: Goto
http://bimmer.work and enter the last 5 digits of your VIN.
This will give you all the configuration options (familiarise yourself with the option codes they will useful in step 5)
Step 3: Goto to a BMW parts website, enter you VIN and search for the available parts. I use the following sites:
*
https://www.bmwautoparts.net/
*
https://www.etkbmw.com/bmw/ (This is my preferred option)
Step 4: Browse through the parts categories. You will find the Switch Cluster under "Vehicle Electrical Systems"
Step 5: This is where it can get confusing and frustrating. Based on the configuration options of your vehicle you will
need to find the right part. Factors to consider (multi-function steering, Auto-rain sensing wipers).
Step 6: Once you have the part number start searching on ebay as you might not find it readily available and it may
take a while for your specific part to come on sale.
Step 7: Find a garage retrofitting service to install the parts and code the car.
To summarise the part number will depend on the build options of your car and the above steps should help you figure out the correct part number.
I hope this helps. Let me know if you have any questions.
Cheers!
Umair
