Hi, i have an a6 c6 2007.
I am having trouble with my car i havent been able to use it since 3 months ago, one day it didnt turned on, the wheel and brakes were locked and the car will not respond to the key, so i took it to a shop. After checking it they made me get a Gateway, after replacing it the car still didnt turned on. The technician there told me he needed to check every cable to be sure there wasnt any short circuit. After two weeks, they now told me they found a burned cable and also need to replace this part: 4F0907279A.

This is the one my car had


I have been looking for it on Ebay but i dont know if i have to match the exact same number including the last letter.

For example can this one do the job ?
