A flickering check engine light and rough idle on a Lynk & Co 01 usually points to a misfire or vacuum leak. Here’s which parts to inspect first and whether you can keep driving.
What a Flickering Check Engine Light and Rough Idle Usually Mean
When the check engine light flickers rather than staying steady, and the engine idles unevenly, the most likely culprit is an intermittent misfire. A misfire means one or more cylinders aren't burning fuel cleanly, which can be caused by worn spark plugs, a failing ignition coil, a weak fuel injector, or a vacuum leak that throws off the air-fuel mixture. On the Lynk & Co 01, which shares much of its drivetrain architecture with Volvo's T5 engines, these symptoms often trace back to the ignition system or a small air leak at the intake or PCV hoses.
