My car is going into the dealer next week anyway, and they just added this 93H3 recall to the job. When I asked what it was, it seems to be a new sticker on one of the charging cables. So I wouldn't make a special trip to get it done!
my car apparently had this recall done a few weeks ago when in for a DSG oil change. Both cables were in the car when it went in for the service, but I've just looked and neither have a shiny new sticker
