I have connected the interface... connected and everything, within in the kombi, I read and I read the memory, gives me pins and km in the framework precise.
to try and take off my 1000 km to the ones originally written, I press the key change, I see that tells me finish and the km framework are always the same, I reread and tells me that I have changed.
