A flickering check engine light and rough idle in your Polo VI usually point to ignition or fuel issues. Here’s what to check first and whether it’s safe to drive.
If your Volkswagen Polo VI (the current generation) has started idling unevenly and the check engine light flickers intermittently, you're not alone. This combination usually points to a partial misfire or an air/fuel mixture problem rather than a sudden catastrophic failure. The flickering light tells me the engine computer is seeing a condition that comes and goes — typically something that upsets combustion at low speeds but clears itself under load.
