So I read the TSB and such on the coolant compatbility for G12evo and was left wondering why G12evo is compatible with all G11/12/13 factory filled vehicles except for the 2015 TDI models? I know there are theories floating out around there but was curious if anyone had a technical explanation to this omission.
