I think most errors that can be explained have good descriptions. 8301: cannot download data. Any thing unclear here?
We have some errors may happen in different cases, example the very famous error 1019: this error may appear when you mount an unavailable ecu in the model list, or main server is down. How you want us to explain this?
Reference numbers are only for support and developers to indicate the possible cause of the problem.
Usually programming tools will have one global error: programming failed. ☺️
i had many cases where i was getting just error , some numbers without any words added to it.
and most of this happened when i was outside on customers site, trying to do something and it just stops with error.
in that cases, even have no clue where to dig what to change.
it is very stressful and i look very unprofessional in customers eye.
Whatever case it is, giving at least a clue with few words what caused this error would be very helpful in finding solution.
bmw standard tools give very clear indication what caused error, just for comparison.
so please, try to work on this, to add few words on descriptions, it would be very helpful.
in case of same error number in different types of error, well, add numbers for each type if it is possible
