    I've owned both-

    1.8T sport quattro and now the TDI quattro both 8Ls

    I would have thought the Haldex controller doesn't need to know the engine variant, surely?

    It'll be working off traction from the abs sensors and torque information from somewhere... The coupling itself?

    Doesnt matter what fuel, only thing that matters is wether not the cars have esp or not as the controllers are not transferable from esp to non esp and vise versa
