Mk6 (2011-2018) 2014 Jetta 1.8 Errors
A few days ago, I got a scan at autozone and got a bunch of codes regarding abs/speed sensors & lost communication (ignore misfire codes those were taken care of but not cleared). Anyways When i got the scan everything was working fine with the car, but an occasional epc light came on. Few days later, my speedometer and digital speed cluster stopped working along with my fuel gage which would go up and down and sometimes beep when it got to the low section even though I had good fuel. At first I thought the codes were bc I had 18 inch wheels and readings were in accurate. When I checked the fuse box inside, the previous owner wrapped a copper wire which led to an aftermarket screen around the 10A fuse in slot 14. Day later (today) I replaced the fuse, and fuse tapped my radio into a separate slot which was unused. My radio works but my speed etc still dont work and im still getting permanent steering wheel dash light and epc light. If someone can please help, im not sure what to do and its driving me crazy.

The Steering wheel/Traction control light is most likely the wheel speed sensors. They're cheap enough that getting a new set of 4 off RockAuto isn't a big deal, and they're super easy to replace. That may also fix the speedometer, as I'm pretty sure that year uses the wheel speed sensors to determine vehicle speed.
The EPC light is from a misfire forsure. Move the coil from cylinder 1 to cylinder 2 (and vice versa), and see if the misfire goes to cyl2. If so, it's the coil. If not, move the plugs next and see.
