I can't say for sure if it's normal for the 12 volt pin to not be active on a 2012 Amarok since they aren't marketed in the US, but I can tell you that most vehicles with a factory 7-way have 12 volt power.

I'd start by checking the fuses. Look at your owner's manual to find which one it is.

If the fuse isn't the problem you can bypass the problem and just run 10 gauge wire using part # 10-1-1 from the 12 volt pin at the rear of your VW to its battery. You want to put a 40 amp circuit breaker, part # 9510, inline with it close to the truck's battery.
