Hello everyone! I want to know if anyone has had this experience with his passat. At the beginning of the lockdown, I noticed a dashboard engine light. I checked it with an ELM OBD2 tool. So it gave a p0401 code. It says flow of exhaust gas recirculation is insufficient. Last week after driving for some time I noticed the check engine light disappear. But after diagnosis the message is still running. Why has the check engine light disappeared? Does this mean there's no problem left? Thanks. Screenshot_2020-07-02-14-17-05.png
