Curious did your invoice show the filters with a no charge, seems like it does based on some of the Audi folk- 2 filters, sku and $0.00. I understand different dealers have different invoicing/billing systemsI just had mine down this week and it passed no issues. I don’t think they changed the oil but was very happy to not need major surgery. Took about a hour for the full service to be completed. Dealership rep told me under 1% of cars recalled will required engine replacement. The impacted parts apparently were manufactured in Ukraine. My beast of a car is entering its second year of service with zero issues minus the 2 recalls.
