After putting and exhaust and a chip on my car, I had the unfortunate occurence of a blown coilpack. I read a thread a few day ago that after putting on some mods the coilpacks are more susceptible of blowing. Im planning on putting a big turbo in my car within the next few weeks and was wondering if it would be good insurance to put on new coilpacks as well, since the dealer only changed the 3rd cylinder one.

just carry some spares.

A coil pack is made up of a coil and a small PC board with an IGBT and a few capacitors, diodes and resistors. All it does is fire a spark across the plugs....it has no idea if there are mods are not. The laws of physics are in effect here!

but it happened to me a couple weeks ago too. I had the car for 40K miles and no failure and when I put the chip back in it for the person who bought it from me the coilpack immediately blew. I replaced it right there since I have spares and no more problems. Odd, I agree. cheers! Mike

definitely. My dealer tried to tell me when I blew a coilpack that it was due to my using NGK coppers, and changing them every 5-6K.

maybe the coilpacks don't follow the laws of physics? =)

I carry all 4, faster than trying to sort out which failed on the side of the road.

I am bone stock and my coilpacks crapped out a while back. I don't drive the car too hard either.

If so, these coils can crack very easily if you don't use the Audi coil removing tool. Especially if you pry up one side at a time with say a screwdriver. I seriously doubt the chip increases the coil duty cycle(time to charge coil/time to fire)as there is no benefit in doing so. Coil supply voltage is a set voltage so the chip wouldn't modify that parameter. I would say there was minor cracking involved if you removed the coils and then they went south....
