I read a post here regarding how to resolve the E-Diff problem I have. Having tried all the ideas I am now left with replacement. Reading the article 2 part numbers were listed EX53-4C118-AD and HY32-4C117-AD

I bought a second hand HY32-4C117-AD and proceeded to replace mine today only to find I have EX53-4C118-AD which is mounted in the boot/trunk above the fuse box. I am sure my EX53-4C118-AD is burnt out judging by the smell.

My question here is where and what is HY32-4C117-AD? Do I need this also if so where is it mounted? Current: 2014 4.4 TDV8 Autobiography 110k miles......will it make the 200k like the Boss did1
