Only took me about 5min to get full access to the cluster using my trim removal tools. No broken clips!
For VCDS, on top of copying over the adaptation settings for current mileage, etc, you will need to go into 17-Instrumentation and set it in Coding>Long Coding Helper as follows:
This will tell program the module for North America. Until I switched it from Great Britain and Passat/Wagon settings, it threw codes for airbag, ABS, traction control etc. It was NOT happy until I changed it to the proper coding.
Next, go into the adaptation section for 17 - Instrumentation, and set the following property:
Until I told it that the oil thermal sensor was NOT connected to the cluster, it thought the sensor was bad and caused an error. We don't have this sensor in our cars at all.
Finally, you can change the theme of the cluster:
Themes 1 and 3 are exactly the same and have the striped background with black buttons. Theme 2 matches with the RNS315 and has gradient backgrounds with silver buttons. I stuck with theme 1/3 since I like the black buttons.
Just make sure you copy down all your settings in your current cluster for mileage, service intervals, etc. These will all be in KM and must be reentered in KM when you go in and program the new cluster.
Good luck!
