    I have never found "real state of tank" in some of these cars.

    It's almost like VW is trying to hide this, because then it would be easy to see that the car uses less than one might expect it...

    That would have been fine too. What we object to is opening two different threads with the same question(s). :)

    Wouldn't be the first time we've seen bugs that produce misleading results in a VW ECU. How long have you had TDIs? Remember how they used to number glow plugs improperly?

    Have you considered reverting your "commonly done VCDS tweaks"?

    Have you got an Auto-Scan from before you started those?

    I doubt that's possible. The T1's electronics were designed in the early 2000s before white LEDs were a thing, and before there was much flexibility to lighting configuration.

    Let's just say we aren't as trusting of that particular source as some of the other outfits in this industry are. That source is not "official" and none of us are privy to much of anything...
