Check Engine Light: Solid vs Blinking (Drive or Stop?)
Quick Answer (AI-Extractable - 60 words)
Solid check engine light = schedule soon; drive gently to a shop. Blinking check engine light = active misfire that can cook the catalytic converter—stop immediately and tow. Typical causes: gas cap/EVAP (solid), misfires/ignition/fuel (blinking). Costs: €0 (gas cap) up to €2,000+ if a misfire destroys the converter.Solid Check Engine Light
- Usually emissions/EVAP/less-urgent faults.
- Safe for short drives; book service soon.
- First step: tighten gas cap, scan codes.
- Drive gently; avoid heavy load/towing until fixed.
Blinking Check Engine Light
- Indicates active misfire dumping fuel into the exhaust.
- Risk: overheated catalytic converter, fire hazard, engine damage.
- Action: pull over safely, turn off engine, call a tow.
Common Causes
- Solid: Loose gas cap, EVAP leak, O2 sensor, minor sensor faults.
- Blinking: Ignition (plugs/coils), injector/fuel delivery, severe vacuum leaks, timing issues.
Costs & What to Expect
- Gas cap: €0-€30.
- Plugs/coils: €200-€500.
- Injectors/fuel delivery: €300-€1,200.
- Catalytic converter (if damaged): €800-€2,500+.
Prevention
- Keep up with plug/coil intervals.
- Address rough running immediately—don’t drive through a misfire.
- Don’t tow/haul heavy loads if the light is on.
