    a failed coil pack will make the car misfire
    and make the em light flash

    Log some values in VCDS, I had a similar issue when my MAF was problematic and not metering air correctly.

    Ive had it on a turbo car before where it was bad fuel. Made it feel like it was misfiring all the time. Put some fresh v power in and was perfect again.
