[Uber Commuter]

Just a hair shy of 150,000 miles now - and I got the dreaded "improper exhaust fluid" error... It gave me 201 miles to no-start, and I drive 120 miles round trip to work...

Got it back home with 155 miles left; driving my Mini until I can fix it...

In your specific situation, if you have ISTA or similar, you can reset the SCR adaptations and it will go back to no countdown for a while, giving you time to drain and refill. It will come back as it reviews the adaptation measurements, but at least it gives you time.
Let me know if you need extra help.

Good to know but I only have Carly unfortunately. In reading up on this, it seems it could be the NOx sensors or the metering valve in addition to possibly being actual bad fluid; so I'm debating on where to start.

With how much I normally drive, the DEF is never in my tank longer than 3 months anyway so fluid going bad was never a concern. This year has been a bit different obviously...

Didn't mean to hit enter yet lol...

What requirements are there for ISTA? I am quite familiar with coding software and have VCDS for Volkswagens (as well as a CAN-USB cable), but I have no idea if ISTA needs a specific cable, or just software, etc?

Thanks!

This has happened to me after putting a more questionable fluid inside, so in my case I can confirm it wasn't the NOx sensors.

Send me a PM with your email or something and I can see if I can help a bit. You do not want it to get to zero.

Don't want to hijack this thread but what advantage is there to staggerered wheel setups. I would think the inconvenience of buying tires, not being able to rotate them easily, etc., would really make this not a great idea. What say you, FaRKle? P.S. I'm a fan of your YouTubes!
