Has anyone made or know where to find a DIY on ECU removal? I searched and found a few post here and other site about where and methods but no DIY videos or write ups.

your going to have a hard time if you have a c63. the new ones are not easy to remove. it either involves removing the coolant res and coming in from the top or the wheel and various other things and coming in from the bottom.

We do not have a PDF for the W205 C63s.

But we have a step by step guide.

1. Remove all three under trays
2. Unscrew the two E10 bolts holding the wiring harnesses to the top ECU bracket
3. Unclip the two coolant lines attached to the front of the ECU lower front bracket
4. Remove the single E10 bolt from the front of the lower front ECU bracket
5. Remove both electrical clips that are plugged into the ECU
6. Slide the ECU forward slightly approximately 1.5”
7. Remove the 4x T30 screws retaining the front and rear lower ECU brackets
8. Remove both brackets from the vehicle
9. Now slide the ECU forward almost into the fan
10. Start to push the ECU to make a 90 degree turn
11. Being careful not to damage the fan or the coolant reservoir while pulling the ECU out of the bottom center of the car

I wish the ECU was "visible in the center of the engine bay..."
