Cobb Tune

[Schurke]

Does the Cobb Tune (or for that matter any TUNE) software leave a trail when it is removed from the ECU? Can VW service dept easily determine if the car has had a tune?
I am a new owner of a 2019 R and still trying to educate myself about the car and what I can or cannot do.

Any flash tune is considered to be detectable by VW. A piggyback may not be detectable if its removed prior to bringing it in to dealer.

Search and you will find tons of info...and alot of disagreement

Yes your car has a flash counter which knows how many times your ECU has been flashed. It's not the dealer that knows it's VW when the VW dealer connects your car.

Wax on, wax off..... Counts each time

You can run a Power Module or Juice Box until you get comfortable with the idea of a flash, or until your warranty is a little closer to expired. Figure about 15 minutes a go for a clean job every time if you use ramps and wire tie to ensure nothing gets snagged. It takes longer the first and each if lighting in the working area is poor as the connectors are easy to plug/unplug once you actually see them. IIRC A pick was handy.

So are you going to tune it?

Probably not. I'm happy with the performance as it is. I have no plans to track the car....at present.
