Flashing Coil Light on Dashoard

[Thegirlparaglider]

Any ideas what is causing a flashing coil light on the dashboard??

 

I hit  a small deer last week so the car was at the dealership for a new bumper.  After 2 days I picked it up and after 10 seconds of driving the coil light was flashing on the dashboard.  I returned the car to the dealership and they kept it for 2 days and replaced a pump that supports the turbo.  So, happy to get my car back I pulled out of the garage and sure enough after 5 seconds the coil light was flashing again....

The service manager was truly shocked that it was still faulty after they had tested it before I picked it up...

 

So now the garage has had my 7 month old Q3 (with 7k miles) for a week and I still have no sign of when I will get it back...

Very annoying as it was perfect before my first trip to the garage...

 

Any ideas on what is causing the problem??
