No one but VW will know this. I doubt they could tell anyway unless you grossly overdosed or used some non off the shelf "additive".I got the letter that specified 2012 Passats. I'm near 100K and will hit 120K easily within the next year...
The extension states that the fuel must be "uncontaminated" for warranty coverage, so does that include 'contamination' by additives?
