Hello,

 

I have a query..i did some changes on my map on AR 159 1,9jtdm but while loading and almost 100%  downloaded mistakes come up…and I can’t do nothing even start the engine..Once more time I connect to the unit to upload the old map what was already in the car and it works again .Dont you know where the problem could be? Someone before me already did some adjusting on the map and made there a chip..do you think it could make an influence on it?

Thank you for help.
