I dont think the flash counter tdetermines the TD1 flag/chip tuning for vw or audi.Also professional chip tuner have already figured out how to reset the flash counter either way.Its more actual changes in the software that trigger the TD1 flag.On that note when a vehicle is brought in for service or any type of diagnosis the modules are read.At any time the vehicle is at a dealer lets say for a oil change.The odis software still checks the software of each module,in order to reset service light,a scan with odis must be made.Note this is only at the dealer level.However this is done in the background the technician does not see odis checking and verifying software.Just about all dealer level scantools have a dedicated online connection via wifi which then goes to the server in germany.Once the "log" is received it is then determined wether changes to software were made by the server.The td1 flag on vw audi will show up on the national report for the vehicles vin after about 15minutes.
Also a chip tuning/td1 flag only affects the drivetrain warranty so engine damage or transmission damage will not be covered.But everything else should still be without issues.However if the vehicle is flashed back to stock it should be a problem wether your reset the flash counter or not.
