[Vwdiesel] Acc'y position on ign switch, A2s

[Tad]

Not to nitpick, but powering a radio from the ignition switch(especially a
"thin" wire) doesn't seem like a good idea.  One would be better off finding
the appropriate terminal in the fuse block and using that... which IIRC is
what I did in my A1.

Maybe my memory is failing in my old age, but I thought the A1s (and
definitely A4s, never owned an A2) would keep accessories powered after you
turned the key off until such time as you removed it.
