My 02 Jetta TDI alarm quit working. It says the hood is open all the time and the wiring checks good.

I think it's the BCM and I have another Jetta BCM but the last letter is different. Does the letter make much difference? MIne ends in an L and I think the spare that I have ends in a C or M.

Did you search the part# on line to see what cars each fit?
Many parts the letter is the revision.
