I'm trying to figure out exactly when my diesel gate warranty will expire. I know it's 10 years after what? Initial purchase date or mfg date? I checked the vin on the warranty info page on VW.com but it just shows my car received the repair oct2018. I purchased it second hand , nov 2018. Not sure what the original sale date is but think I got a Carfax that shows it from the used car lot I got it from.
