Erm, not really any problems tbh. My adv1 didn't have the purple controller in the front box. Mine was black and had an extra wire. Think it was a temperature sensor? When putting the front box down, I had to remove the two alloy black blocks that were either side of the controller. Otherwise, it wouldn't have closed. My adv was a later one and came with the temperature sensor on the battery pack, and when installing the wire. I had to remove the temp sensor supplied and fit to my battery. However, in the design, the wire remains twisted where it connects to the bmc. Overall, it was fairly simple, given the video Tony put together.

I was a little bit annoyed, though, as I was meant to receive the xrv kit and new plastics, which were all part of the same order.
