Def system failed- cel came on w def light stating xxx miles to no start, codes p204f & 18097, now unable to start or drive car safely, 18097 code may cause abs & steering to shut off while driving & p204f renders the car unusable. EPA mod was never performed on my car per dieselgate settlement rules- & now the manufacturer(vw) is refusing to fix their mistake car has been in shop repeatedly for 30+ days at a time since 2022 for the def system and not once was the epa mod mentioned to me VW refuses to fix the def system or do the epa required mod- meaning I was sold a stop sale car. Also claiming Im not entitled to warranty even though per their own warranty I am the first owner that I can see other then a dealership Am now told by other TDI owners that are still under warranty that vw is refusing to fix anything to do with the p204f code
