    Audi A4 1.8T B7 Need to code the ECU For Manuel Transmission

    Hello all,

    I have an Audi A4 1.8T B7 shape and the vehicle used to be an automatic but someone converted into manual. Now the problem is i have to find a way to code the ECU so it has the information for Manuel Transmission.

    Current Software coding is 0004581 and i need to change it into 0004501 but it just keeps rejecting the coding. Could anyone tell me what i am doing wrong or tell me how am i supposed to sort this problem?

    Thanks

    We'll need you to post a FULL Auto-Scan to be able to suggest the correct coding - if it's possible.

    Many (but not all) ECUs have transmission-specific software in them and won't accept coding for a different transmission type.

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    That's what I was hinting at when I said "if it's possible"
