Not to confuse the matter but membership FYI: 4-Pin vs 5-Pin - originally manufactured with 5 electrical pins, the replacement part may have only 4 pins. The 5th pin was never used, and the 4-pin version is correct.
My car is a 2008 c63. I want to replace the tcm as I have a fault code Y3/8n4 which I believe is the processor fault.
How do I know if my existing tcm is 4 or 5 pin without removing it first ?
Thanks
