I have a question has anyone successfully upgraded there rear end with a newer model rear end? I have a 2013 tiguan and I have a 2016 tiguan rear differential that I would like to use on my 2013. Is this possible? The difference I see right of the bat is the Haldex unit is different and there are extra wires in the connector that I have no idea what it is for or where it goes to.
Why am I doing this because of a bearing noise problem on the drivers side axle / diff side.
Does anyone have a electrical schematic for a 2016 tiguan Haldex? I'm also wondering if I'll have to do coding with that as well.
Any suggestion would be great.
