    Sounds like you've dropped a cylinder. Check your coil packs and see if one has failed.

    he has a 99, coilpacks are less common on AGU engines. I'd go for ignition module first. Thats what mine was.

    Phone your local Audi dealer's Servicing Dept and check if your car is on the recall list for free coilpack replacements!

    If it has an ignition module, i'd be swapping that out before the coils.

    When they fail they often drop cylinder 2 first.

    swap coils and see if the misfire follows the coil or the cylinder will confirm obviously

    A4/A6/Passat with an AEB/AJL motor also use the same coils and ignition modules as well

    I've got a spare you can try if your local.

    undo the coil pack connections one at a time, then you would know which one is at fault.

    My misfire was a duff HT lead. Remember to check these, as I changed the coil pack and plugs before realising this.

    Pull each coilpack out to test which one has failed, swap that coilpack with a working pack. If that coil doesn't work when swapped with the working one, it's the ICM.

    Does the BAM S3 have an ignition module? Mine dropped cylinder 3 tonight and I'm wondering if its coilpack or, if it has one, the ignition module. It's been idling a bit dodgy recently too.

    Sam, yours is most probably going to be a coilpack mate.

    Give Audi a call, they maybe able to swap it under the current recall that they have running.
