Without the right to repair the deere john letter forces you to purchase and use only factory air filters (technicalities considered), it’s only a regulation away.Welcome to any conversation with Zig. Most of us are equally lost.
We obviously have very different systems in our respective countries. What I've seen owners and DIY'ers do makes me very happy we have a thorough inspection system.we oversee the quality of the repair as owners and or diyers i dont want anyone inspecting my cars their mine.
seen the inspection guys in ny hitting the cats with hammers to "make sure they are not gutted"
i left luckily it was not my car they do more damage than good.
my inspection stickers now come from Facebook market place
Define ‘emissions’ system?The regulations have ZERO to doing filters. I have a lot of experience with John Deere which is why I use them as an example. Majority of their software is “proprietary”. Even the minor updates. Majority download automatically when you start the engine. But if theres an issue while working, you’re not allowed to dl it yourself. It’s only about nickel and dimeing.
