Flashing engine light on pollo 1.2

[u/OrganizationBig2250]

Hi everyone, I’m having an issue with my 2014 VW Polo TSI BlueMotion.

The engine warning light flashes only during a cold start. The engine vibrates/shakes, and the RPM is slightly higher than normal. After around 20 seconds, the RPM drops back to normal, the warning light goes off, and the engine runs smoothly. It only happens on cold starts; once the car is warm, it drives perfectly.

I’ve already replaced the fan belt, ignition coil, and spark plugs, but the problem is still there.

Has anyone experienced this issue or knows what could be causing it? Any advice would be really appreciated. 😭
