I have been having the check engine light come on and off…

Customer Question
Second opinion] Hello, I...

Second opinion] Hello, I have been having the check engine light come on and off since 2015( I own a 2013 VW Passat SE) when I purchased my vehicle, but it always resolved over time after re-tightening the fuel cap. I even had my fuel cap replaced by you guys last summer, which seem to help. Last week I experienced my vehicle having issues accelerating with the check engine light now doing a little different activity, flashing. I did a little research and replaced my purge valve solenoid (on 3/22/2018), which seem to have resolved the issue until today (3/27/2018). The engine began to run lean which caused the EPC light as well as the flashing check engine light come on. I got a diagnostic at a local auto parts store, which gave me 2 codes, P0456 & P0302. The P0456 is the same code I had seen previously but the P0302 had never occurred. I addressed that code by replacing the #2-cylinder coil as well as replacing the sparkplug with new. This seem to have stopped the engine from running rough as well as the EDC light went off however, I could still feel a little hesitation. I watched the gauges and saw it moved from the middle maker of 190 to slightly above (not staying just going back and forth).

Mechanic's Assistant: Does the light stay on, or does it blink?

It does both

Mechanic's Assistant: What is the model of your '15 VW?

I have 2013 VW Passat SE

Mechanic's Assistant: Are you fixing your Passat yourself? What have you tried so far?
