I purchased my first E53 in December of 2021 just two months ago.

The car is a “low spec” 3.0 car as it has the smaller display for mileage and OBC menu items. I have been wanting to do a 4.6is cluster retrofit if I ever came across one. Thankfully, a friend of mine nabbed one and is sending it over to me!

I have a couple questions as to how much coding/ work is needed to convert, and who might be a good recommendation to send it to. Glancing through the forums I’m seeing there’s not a lot of information in this topic. I know there’s a lot of support for this type of thing in the E46 community, I assume the concept would be the same for E53/39 clusters

My main concern with this conversion is the OBC menu information and the fact that the “low spec” cars didn’t have a coolant level sensor.

Will I run into issues with the car not being able to display some OBC menu information as it is much more detailed in the full size display clusters (date, timer, etc.)?

Also, any recommendations as to where to send the cluster for VIN & mileage matching, along with getting the adjustable redline set up correctly?

For reference, my model is an 01 3.0 5 speed
