I am not sure, as when I replaced mine they were not throwing any codes. But I could tell that the engine rev quicker and it felt like she pulled hard after putting on the Bavauto. Whether it is from old coils or not I can not say. But I can say I did pick up more power from that mod. As hard as I run my X I noticed those things. But then again I should have boughten the 4.6 or 4.8. There is absolutely nothing wrong with the the OE coils, but if one wants to squeeze out every ounce of power these are the way to go. After I was done with all my bolt on mods I have Active Autowerkes tune my ECU for those mods and that yielded yet some more power.
Now all that being said I should have just bought a supercharger for my X and quit wasting all my money on those little extras that didn't really offer a whole lot of HP in return. But you live and learn. Now I just drive my M.
