Loosing my mind here people! I have replaced all the spark plugs and the coils on my 2003 Beetle Turbo 1.8L at least 4 times, but the coils keep going out. I will replace one and it will work for like 30-45 days and then go out again, since I did not replace them all at the same time they go out randomly! This is killing me do you think there could be something causing this besides the coils themselves? They are aftermarket, and not the actual Volkswagen brand but I bought them at an auto parts store not online or anything. PLEASE HELP!!!!
