    Hi, I searched the forum and I found a couple of threads on the topic. So I thought it would be a good idea to put the info in one thread plus the questions regarding the relays.

    1. Bosch old number: 0 332 014 113 -> Bosch current number: 0 986 AH0 251
    2. Bosch old number: 0 332 204 101 -> Bosch current number: 0 332 209 151
    3. Bosch old number: 0 332 015 006 -> Bosch current number: 0 332 015 006 (???)
    Regarding 1) I found this thread https://www.ferrarichat.com/forum/threads/bosch-0-332-019-151.691303/#post-149816101. Does anyone have any interjections and would use a different Bosch relay instead of the 0 986 AH0 251? Even Bosch Classics in their product search https://www.bosch-classic.com/de/de/produkte/fahrzeug-und-produktsuche/produktsuche.html?query=0+332+014+113&prodKey=0332014113#produktsuche lists 0 986 AH0 251 as succession.

    Regarding 2) Is discussed in the same thread. Any interjections? Bosch Classic https://www.bosch-classic.com/de/de/produkte/fahrzeug-und-produktsuche/produktsuche.html?query=0+332+204+101&prodKey=0332204101 lists 0 332 209 151 as succession.

    Regarding 3) Here is where it gets confusing. Steve Magnusson in https://www.ferrarichat.com/forum/posts/149816817/ mentions that "Kind of surprised that Bosch would reuse that same 0 332 015 006 part number for a different construction relay."
    So is the new 0 332 015 006 a different relays now? Bosch Classic lists the part as still in production: https://www.bosch-classic.com/de/de/produkte/fahrzeug-und-produktsuche/produktsuche.html?query=0+332+015+006&prodKey=0332015006 and with Ferrari part numbers: 110354 and 40 28 39 05.
    Does anyone have the exact diagram from the old K relay? Then we could compare in this thread with the new one.

    Best, alexkay

    I'd change my comment here after seeing the actual markings on that relay in post #2. That V231... part number (and the plastic outer case construction) is the later Tyco brand part number nomenclature -- so it's more that Tyco (or whoever now owns the Bosch relay business now) just added the old Bosch part number for reference (rather than Bosch reused the old part number).

    @Steve Magnusson Do I understand you correctly that you would also say "Bosch old number: 0 332 015 006 -> Bosch current number: 0 332 015 006"?

    It's more "Bosch old number: 0 332 015 006 (metal case) printed on an equivalent relay (plastic case) made by a later company" (AFAIK, Bosch either sold, or licensed, their relay business to other companies. Bosch would have no reason to print a Tyco format part number on a relay that was truly made by "Bosch".)
