    Hello,

    While I'm driving along my dsg box is rocking so to speak, the revs will drop slightly and pick back up and make it rock, happens at steady throttle. Any ideas or fixes??


    Cheers

    Also when i just casually accelerate out of a junction or something as it picks up revs, it will stop building up for a millisecond like its losing boost

    Is this happening at low speeds...mine selects 2nd a bit early sometimes and the outcome is similar to the above

    If physically rocking then check mountings.

    If the revs are dropping sounds like an air leak to be honest, then the box is a consequence of that?

    Narrowed it down a bit an it does this violent jerking motion is when I'm in first and second accelerating slowly Like in traffic or what not, and also in 4th sometimes, it's as if it's trying to change up or down like it doesn't know what to do, could it be the mechatronic unit maybe?

    The mechatronic issues will show up in reverse gear backing up a hill. Same thing, jerky drive.

    Quick update, had the dsg serviced for £150 from audi and feels a million times smoother because the last time it was done according to paperwork I have was 08! but still have this slight rock mostly at light throttle. Need to fix the oring on the inter cooler and give the sticky vanes a sort out as I had an over boosting fault a while back
