    Timing cam crank sensor correlation error, VCDS block 090 show "99"

    Guest-only advertisement. Register or Log In now!
    Built engine, new timing belt.
    AMU engine.

    First start, runs rough.

    Timing blocks in VCDS Vagcom (block 090 to 093) show "99 degrees" and error code "cam sensor and engine speed sensor correlation".

    Timing checked. Crank at TDC mark. Cams 'square' marks both line up with mark on bracket, exhaust cam timing belt sprocket mark lines up with valve cover mark.

    Timing chain has 15.5 links between marks (counting first link on mark, 16th link just past mark).

    Any suggestion what might be causing issue?

    Engine runs smooth, but 17748 code (cam/crank sensor incorrect correlation) remains.

    Checked timing again yesterday:
    - With crank pulley at TDC mark, and exhaust cam sprocket mark lined up with valve cover mark, the CAM marks (squares) are OFF.
    - Moved crank until CAM marks line up with triangles, then cam sprocket/belt is off by 3.5 teeth

    Do I have the wrong cam sprocket?

    Or is the cam sprocket installed the wrong way?

    There is a timing mark on the other face of the cam sprocket. The part number stamped (facing outside) is 027 101 111 H.

    4 hole cam sensor installed (and swapped/tested).

    Block is built AMU (TT225), head is AEB.

    Just looked up the part number on the sprocket: it is the AEB sprocket. Didn't think there is a difference, but apparently there IS.
    The TT225 sprocket shows up as 06B109111,

    So now: what is the easiest way to change out the cam sprocket with the engine installed? Any suggestions or tips?
