So, my name is mihai i recently (last week)bought a 2005.5 b7 audi a4
Great looking car love it. Its my 2nd audi that im owning.
*drove the car 2 days ago and car started shaking and the check engine light was flashing. I stopped in a parking spot opened the hood and one of the coilpacks#2 was smoking.
There was a audi dealership within walking distance. went and bought 4 new coils and installed them. also bought 4 new sparkplugs and a new battery.
when i tried to start the car it wont start.
what could be the problem? could it be the wirring harness? fuelpump?
car is currently at the dealership getting a diagnostics.

please if anyone had something similar helpp!
