You need to get a fault code to work out which part is playing up. No the haldex controller and pump do not get fixed.

There is info on the net about rebuilding the precharge pump and / or replacing it with a pump from a Volvo / Saab / Vauxhall / Mazda etc, which all use Haldex.

The pump is horrific money from VW, but Lucifer usually has a good stock of them!

If it's not the pump and ECU related, there isn't much you can do about it other than replace it.
