Well VW customer survey is suppose to cost them a fortune in money if they get a bad one according to EVO on here and also my friendly helpful local dealer. I just hope i get a phone call but i think its too late for them to call now or maybe there waiting till my case with VWcs is over 
Don't let them off the hook.
I think there is a certain time span for complaints to be resolved. Anyway, you waited 7 months for your car, so what's their hurry?
You have been too nice and patient with them from what I have read and seen.
