Mind, if the power distribution is not balanced there may be a minor effect
that the one at the end of the line gets less voltage.
The effect on battery voltage is minor, or should be, and in any case the
plugs are mean to be able to handle 12V.
There's also the point that on a TDi, 2 plugs are probably enough to make
sure that it starts...
Still good practice top replace the set though - it's like spark plugs, no
point in changing part of a set, except if one gets broken or something.
