Well, that's special case, situation when there is some problem
Unless that has happened, there is just one "problem" - some rather long distance with wires of average gauge - but that won't be problem for cars with moderate power NA engines, unlike, let's say, the same thing with headlights - because of that I even didn't bothered to upgrade something for pump wiring of my 2.0 8v mk2 golf, which in VW is even worse than in audi, as it uses main fusebox ground - while headlights have thick wires integrated in loom and pair of relays on top of fusebox, giving "oncoming truck" effect....
