Mercedes Clk 240 w209
There is no way of replacing the instrument cluster of CLK w209 to a digital instrument cluster. You can try to retrofit a W211 instrument cluster but that's it. I know this cause I have been working on this for about a year but haven't found a replacement. My cluster is working fine but it's dusty and obviously looks vintage. However there no solution to this. So to burst your bubble. 😊

W209 CLK
It's really not that simple. The biggest primary issue is that a lot of the sensors you would really want to make this work don't actually work on OBD2 they work on K-Line. There are off the shelf products such as Torque for Android that you can use to build a digital dash. Your problem is accessing all of the sensors that work on the K-Line bus which is pretty much everything beyond the obvious available to you. Speed, RPM, and water temperature work on CAN but oil temperature does not.
I've tested this with a basic ELM OBD sensor and Torque on an Android Head unit.
So yes you could build a digital dash, but at present it would only replicate the basic features on the CLK dash. To go beyond that you need somebody that can program the K-Line bus, and that's not me. I don't begin to understand the data that it spits out, and it's not in any familiar programing code anyway.
So where you hit a brick wall with this is not so much that you can't do it, it's the fact that all of the useful sensors you wil want to access are on the K-Line bus.
The only notable work around this if you don't want all the notable AMG related stuff is to install sensors yourself and have them recognised by PID on an app like Torque.
The only work around for that at present is finding an AMG dash and having someone with a Xentry program the dash for your car.
It's very possible to install anything that runs vanilla Android and build a dash using Torque... Unfortunately you live in a walled garden by Mercedes Benz where these cars are so old all the useful sensors you would otherwise want run on K-Line.
Knock yourself out build a dash running Vanilla Android on a Rapberry Pi, you're still going to run into this issue though unless you can magically find someone who can interpret the K-Line bus and that's not me.
