Hello everyone I am asking for any insight on some of the issues I have been having with my vehicle. I have a 2013 Prestige A4 S-Line and manual transmission, 63,500 miles. I have been in and out of the dealership multiple times with either the check engine light on, or the EPC light illuminated. With that being said, They have had to replace the engine coil to the affected cylinder every time this has occurred, with the last time just replacing every single coil rather than just the one that was malfunctioning. I have asked if they are just fixing the problem at the present time and not fixing the problem that is causing this. Has anyone had any similar issues like this before with the EPC light being illuminated and the car shaking while driving?

Next I have had a problem more recently with my steering being hard to turn, and having to use a decent amount of force to get it back in the straight position. Has anyone encountered this same problem, and is there a solution to fixing it?

Any sort of insight would be greatly appreciated, and thanks in advance for your time.
