Coil light and Fault Codes

[nellymcl]

Hi All

I am a new member here so firstly thanks for the support.

I have a 2.0 TDi Auto Quattro Black Edition (2017). I love my car and have had it for over 3 years now. A few days ago I got a flashing coil light on the dashboard during part of a half hour journey. This did not come back on since then in the 2-3 other journeys I have done. I did manage to get the fault codes which are below

2 Faults Found:

There was also a little smell of what I think is diesel when driving, but only on the journey after this happened.

Any thoughts?

Thanks!

P2100 appears to be a common problem. Here's a thread on how to fix it:
