Am I right in assuming VARDEF allows for an additional softcoding variant without throwing the "control module incorrectly coded" DTC?

I ask because I changed VARDEF in an L-box, and noticed anytime I softcoded to a previously good variation (06651) I'd get the above mentioned DTC. With VARDEF @ 06651, no such code.

VARDEF is the default coding that will be set with your new ecu. If you get the DTC then you have wrong coding. For example: you try to change gearbox from 5speed to 6speed. Would be simple to just change one bit, but in reality your bin has to support that. I would guess that setting vardef to incorrect setting would ignore dtc check, but that wouldn't mean that you have correct setting and car is behaving as you expect.

Are you sure about that? I ask because it's 6611 in the m-box, and to my knowledge m-box cars all had esp. Doesn't make sense that 0611 would be the default when that would make the coding incorrect out of the box. I figured variant was just that, a variant on the original softcoding.

Thanks!

(and I'm not saying you're wrong, just asking for clarification)

Might not apply to this case, but on many occasions out-of-the-box coding is incorrect, or zero.
