Unless you have a known problem with your car or fuel, there is no reason to use an additive. I am now going strong at 430,000 miles on my diesel vehicles without a fuel related problem and no additives.
High pressure fuel pump failures have been reported in VW common rail engines but so far there is no proof any additive would have helped.
The oil companies already use additives that are specific to the base stock available.
