    Hi I know this has been covered before, and I spent a few days on forums reading around. but....

    I have an audi a4 b6 1.8t auto.

    Car wasn't a lot of money and has been ok for a while. 93 k 3rd owner with history

    PRNDS flashing and it appears to not select or drop out of gear.
    about 1 in 4 or 5 times its driven.

    box is smooth and car drives nice other than that

    I know these suffer with this issue.

    I fitted a new battery and had to unblock the drain holes as there was water there.

    basically, what the best resolution for this. Seen a guy advertising £155 on ebay and says lifetime guarantee with better parts fitted. and is the ecu near the battery or at back of gearbox.

    Also thought about doing oild and filter on auto box, but dont want to throw good money after bad.

    Thanks in advance for your time folks

    I thought the CVT TCU was embedded in the transmission itself.

    Thanks for your reply.
    Wasn’t sure if cvt and multritronic were the same.
    Any more input would be appreciated.
