Hi! I have had my 2016 Jetta for three years. Recently the EPC light came on. It would go on and off and then nothing after throttle was cleaned. Now the EPC light came back on and the engine light is on. Brought it to mechanic and he scanned it, nothing is showing up. Even though the light had been on for three days prior. Do I need to bring it to a dealership and get a better scan? Thank you.
