Come back? I haven't left yet!

Anyway, I have car back, and touching wood it's going to be ok. My VW dealership managed to put at least 7 quarts of oil into a car that only needs 4.4. One oil change later...

We did have a scare on the way back to Lauras - still stuttering, flashing CELs and pumping an extremely environmentally unfriendly amount of blue smoke out of the exhaust, to the point where we turned around and took it back to the dealer. As we got there, the car started to behave much better. I talked to the guy that had worked on the car and he gave me lots of reassurance that it would take a while for the oil to burn out, and that I could expect those issues until it did.

More importantly I asked him to categorically state that the headgasket, oil seals and turbo were all fine. Sure enough, on the way back to Laura's (finally) there was no smoking, and much reduced hesitation. So it looks like I'm about to go to Boston, and hopefully by the time I get there my car will be 100% again.
