Unfortunately you can't solder aluminum like copper. I replaced the aluminum with a small copper wire. I'm afraid that you pretty much have totaled the board from the sound of things. I only compromised one via and used silver conductive epoxy to repair. http://www.ecstuning.com/ This is a company that sells vw and passat modules only. You have to match the number stamped on the top of the valve body with their models. They sell the module only for about $500 depending on the model. If my unit fails again, I won't even bother to open it: I will go right to this place.
