It’s my understanding that the cheat was in all TDI models, but the smaller Jetta was particularly bad because it didn’t have a urea system and the fix for that model was to retrofit one. My Passat may have needed a more robust urea injector and not just software, but I can’t remember now. Either way on my year/model the fix was barely noticeable.
How do you fill a urea tank on a passenger vehicle? I don’t see those pumps at the gas station, and doubt it’s as easy as peeing into a bottle…
It’s just like the DEF tanks on 18 wheelers. I buy a 10L jug of it from Walmart for something like $10. In my trunk there’s a panel you remove and under it there’s a small cap very similar to the gas cap. Remove that, hook up the DEF bottle hose (the bottles come with a 12-15" corrugated hose) and very slowly pour it in. You don’t want to spill that stuff, it’s nasty not because it’s urea, but because when it dries it kind of crystallizes and makes a real bloody awful mess.
Replace the cap, replace the panel cover, close the trunk and you’re done for another 9-15mos.
Huh, interesting. I knew about urea injection to reduce diesel emissions, but didn’t know it was a thing for passenger cars.
My car is a diesel. I believe catalytic converters are the usual fare for gasoline engines.
