04 TT igntion coil caught fire

[Mike Markota]

While driving my car about a hundred miles after doing lots of work on it I noticed smoke (and smelled) a classic electrical fire. I popped the hood and see the coil on the passenger side closest to the front was literally pouring out the densest, most acrid smoke I've ever seen. I extinguished the fire, ripped off the coil cover and saw the coil and connector were totally melted together.  I separated the coil and the connector, pulled the wires that melted together on the connector apart, and tried to start. Everything on the cluster powers up, but not even a click from the starter. I should note I did not touch the coils or any of the wiring besides to disconnect the battery and reinstall the alternator. The car ran like a top for a hundred miles so I'd like to think it is not related to my work.

 

I did some research and it appears suncoast sells the connector, which requires one to reuse existing pins and wirings..in my case that will be impossible. http://www.suncoastparts.com/product/955V8PLUG.html

 

Does anyone know what style pins or where to order them and the right wire? 

 

My research also seems to indicate a fuse is blown as a protection for the catalyst. Would this prevent the starter from even turning over? 

 

Does anyone know what else could be damaged? Or why this happened?

 

Thanks

Mike

Well it looks like 09+ Audi A3 use a similar looking coil connector , which dorman sells a connector kit for. Much, much cheaper. I'll let you guys know how it fits and functions!

I would first repair the coil problem and the fuse, probably an internal short in the coil itself, the starter could be related to the work you have done on the alternator, loading ok? connections ok?
