  • AAN, 3B and ABY, ADU wastegate difference?

    Hi,

    the part number of AAN/3B and ABY/ADU wastegate are differents.

    Anyone know why?

    3B/AAN : 034 145 705 B
    ABY/RS2 : 034 145 705 E

    Is this because of a different spring or is there any other reason?

    Thank for your help

    adjusting screw in the wastegate cap screwed a little deeper for more spring preload.

        Hi,

        I no longer have the possibility to measure it exactly, the adjusting screw from the ABY it just screwed a little deeper in the wastegate cap than on the 3B.
        maybe someone measured it here?
