Hi all a strange one not sure if it’s in the right place but hopefully.So we have a 2.0 TDI manual 6 speed that’s had a gearbox change.Ever since the change cruise shuts off and the gear numbers disappear in 5 and 6 fine in 3-4 etc.It’s a EDC17C46 ecu and it seems the 5-6th gear ratio might be different in the replacement box and the RPM to Speed ratio is confusing the ecu.Also Kess master won’t allow OBD read on this ecu only write and I don’t have Ktag. I’m a little scared to just write a different ecu file without any backup.Any of you good fellows any ideas I wonder if the gearbox was from a higher powered vehicle.Any help would be greatly appreciated.Thanks
