Hi to all i try like a lot of other people for hours to figger this out but the only way to over come the problem is to replace the GEM / FUSEBOX if you are getting a second hand box then make sure that all the numbers match on the replacement one and that it comes from the same type of car and then it can be reprogramed by a garage with the right diagnostic equipment so it can control all the addons which the car as.
hope this helps !!
