yes dealer only can only update if like U said they already did then no need to after actuator was replaced

 

the way it sounds, is the OP doesn't think the dealer did do the update even though they said that they did....




am I correct, that if they did a software flash, they have to put a sticker under the hood saying it was reflashed?

 

I had code P0306 with vacuum leak (at actuator shaft) so I tried the injector ring placement trick I saw on u-tube it failed so I changed the plenum, plugs and 6 coils, runs like new.
