An ignition coil or spark plug may fail unexpectedly resulting in an engine misfire and possible illumination of the Check Engine Light. Vehicles equipped with spark plug wires may also develop a misfire caused by a failed spark plug wire.

    first one ignition coil failed and then after replacing it, in few months, the other 3 failed. after replacing them, few weeks later found out that it's on a recall and it's covered under warranty. I'll try to get money back from audi usa.

    Started when I was leaving work. Check engine light was blinking and car engine was misfiring. I drove it 25 miles to the dealer. It was ignition coil which cost me $280.00

    i had three out of four ignition coils go bad on me. Audi came out with a recall on this, so bring your car in to them and they will pay for it it this has happened to you.

    I inserted a spark plug into a pulled but live coil, grounded body of plug and observed spark on each coil seperately while engine was running on the other 3 cyl. Having found the bad coil I switched it with the feed wire from another cyl. to prove it was the coil and not the wiring. Two weeks later a second coil failed. A week later the remaining two coils showed a weak spark and were replaced. Probably best to replace all coils at one time.

    I've replaced two ignition coils already. The mechanic showed me how to do it myself, because the part is easy to replace and they apparently fail in succession (i.e.: replace one and the others are more likely to fail). You need to test each connection individually to see which coil has failed (the engine will rev with a different sound on the faulty one) and pop in the new coil. Done.
