A flickering check engine light with a rough idle usually means an active misfire. Here’s what to check first — and when to stop driving.
What a flickering check engine light means on a Kodiaq I
If your Škoda Kodiaq I has a check engine light that flickers intermittently and the idle feels rough, treat it as an active misfire warning, not just a loose sensor. The ECU is detecting incomplete combustion in one or more cylinders. On many Kodiaq I engines — especially the 1.4/1.5 TSI and 2.0 TSI — the usual culprits are ignition coils, spark plugs, injectors, or a vacuum leak. On 2.0 TDI models, think fuel injectors, EGR, or fuel delivery. A flashing or flickering CEL can send unburned fuel into the catalytic converter and overheat it, so don't ignore it.
