Hello new member here, My A6 2017 automatic won’t maintain power going up hill ( not a steep hill) rev 2500/3000 . Got full diagnostics done by Main Audi dealer with no positive results . Got ERG mapped out so could be hiding possible fault ? When I get to top of hill power resumes but not fully, goes through gears very quickly almost too quick as in 5th @ 45/50 kilometres per hour. Probably have to get EGR mapping reset to factory settings ? Any advice would be greatly appreciated.
