Diesel owners Have you ever seen this warning?

"Module PCM update needed to correct issue"

So basically all they did was hook it up to a computer and update the diesel emissions control software. Well, good to know that it was an easy fix. I just wonder what that would have cost if it were out of warranty? Or is that on the longer powertrain warranty? When the DEF heater went on my diesel VW way back VW claimed it wasn't part of the powertrain.
In California it would be part of the emissions warranty, which is longer than the other warranties on the car.

Nice to know. I've had one diesel DEF related warning while on a long road trip and the possible outcomes were not good. Including needing parts with several week lead times. But it turned out to be a one-time glitch on my car.

Thanks for reporting the solution.
