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.

There was a sudden loss of power and the engine light was blinking continuously. I was unable to reach 40 mph's and there was smoke coming out of the hood. Had to get the car towed to my mechanic to get #2 Coil Pack repaired, spark plugs and valve gasket cover replaced (oil was leaking). I called Audi corporate and notified that this is an issue and advised there was a nationwide recall. I made an appointment the following day at the Audi dealership and they replaced all 4 coil packs including the one I had replaced for free. I sent in my bill to Audi Corporate to get my repair bill from my local reimbursed. They said it will take about 90 days. Lets see if they pay me back but nothing can replace the fear of your car losing power driving on the highway during rush hour traffic.
I have a 99 A4 Quatro with the 6 cylinder engine. My check engine light went on and the car drove real roughly so I asked a local muffler/repair shop to scan the codes. They got a code incicating an ignition problem but electrical repairs are not their forte so they suggested I take it to the dealer or a specialty shop. I had them go ahead and replace the coil pack as I everything I read on the internet led me to believe this was a common problem. No go! $400 later, another shop found it was simply a spark plug wire. Lesson learned; start with the simpler, cheaper solutions.
Check engine light started blinking about a mile into the drive and the engine started vibrating. The mechanic looked at the fault codes and noted that it was an ignition coil failure and recommended to change it and the 4 spark plugs. He did not change all 4 ignition coils, the problem was soon corrected by my regular mechanic.
