Mercedes CLS55 AMG W219, How To Replace The TCU

When I searched for a step-by-step video for replacing the Transmission Control Unit (TCU), I could not find one for the CLS. Therefore I created one myself, to help out others who want/need to swap out this unit.

My tuned unit was stamped with:

Mini Cooper S R53 JCW – Injector Service

Cleaned & replaced the rubbers on the blue 380cc Siemens Deka injectors. The rubbers tend to get hard and brittle due to heat, so very important to replace these in time.

I will probably replace the injectors somewhere in the near future for peace of mind.
