I will say when you go to the dealer they will try to slime out of it, theyve tried to charge me and say it only pertains to in between oil changes. Quick argument and they usually remove the charge. I've used peak def probably 3 times, ended up with free ones from work and never had an issue until recently and it didn't even turn out to be the def but a nox sensor failing. Couple times I've used vw def and didn't have an issue at all but it's hard to quantify.
