      I’m not too experienced with modding cars, but I want to attempt to upgrade my AWD system in my S60 from a reactionary system (Haldex Gen 2) to a proactive system (Haldex Gen 3). The controllers look similar to me. Is it possible to just swap controllers? What else would I need to do in addition to swapping the controllers? Thank you!

      I don't have an exact answer for this scenario, but what I can tell you, is on these Volvo's, every piece of electronics is tied to every other piece, so if you swap from one car to another, it won't just work.

      Just if/because a part may bolt up, doesn't mean the plethora of computers is going to accept it or use it at all.

      There was a large topic somewhere on the subject - several pages. You may read on one page that everything works fine, then 3 pages later there appear to be problems and sometimes the updates stop short. I'd say, perhaps it's safe to simply try the swap and see what happens, if the parts aren't too expensive. But when I tried to follow that discussion, it wasn't that clear that it always works - may work with some parts (serial #) and not with others. So again, read ALL pages and try to find all posts from those who say it works https://forums.swedespeed.com/showth...t-Gen-3-Haldex

      The original poster comes to this conclusion (post #370) https://forums.swedespeed.com/showth...-Haldex/page11
