^^ that is whack, if it is a TSB, and your car is having that issue, they have to perform the TSB.
As for the ECU Recall, the DEALER SHOULD know!! but it doesn't mean they will do the service, I would go in and be sure to request they perform the ECU Software update, per VW Soft Recall.
If they don't call VWoA immediately explain to them your situation and how shitty the dealer has been to you, and get a CASE #..they will also ask for the dealer you would like to take your car too, and they should contact that dealer. Then next either go back to that dealer or better go to another DEALER and tell them you have an OPEN FILE/CASE with VW, give them your CASE #...and they can call VWoA and they should perform whatever RECALL is necessary and TSB's that your vehicle is experiencing.
