Insignia Crankcase Ventilation Issue

I'm getting seriously frustrated with my 2014 Vauxhall Insignia (gasoline engine). The check engine light keeps popping on, and I've noticed a definite drop in power. To top it off, there's visible smoke puffing out when I accelerate hard. I've scanned the codes and it's pointing towards a crankcase ventilation valve malfunction. Anyone else experienced this?

A 2014 Vauxhall Insignia owner is experiencing a check engine light, reduced power, and smoke during acceleration, with diagnostic codes indicating a crankcase ventilation valve malfunction. The issue is likely due to a blocked or leaking PCV valve, which is part of the crankcase ventilation system responsible for relieving pressure. The suggested solution is to replace the faulty valve, with the recommendation to seek professional assistance if unsure about performing the repair independently.

Sounds familiar. I've got an Insignia too, and I had almost the same symptoms a while back. Smoke, loss of power... nightmare! It could be a blocked or leaking PCV valve. That valve is part of the crankcase ventilation system; it's there to relieve pressure in the crankcase. If it fails it can cause all sorts of issues.

So, if that valve is defective, it could cause smoke? And reduced engine power? Is it a hard thing to fix myself or is that a job for the workshop?

Yeah, a faulty PCV valve can definitely cause those symptoms. The positive crankcase ventilation is not working as it should. As for fixing it yourself, I'm no expert, but it depends on your skill level. It involves getting to the valve, removing it, replacing it, and hoping that fixes the problems. If you're not totally confident, I'd say get it to a workshop.

Thanks for the advice! I think I'll book it into a workshop. I'm not risking messing anything else up. The repair ended up costing me 360€, but at least the car is running smoothly again.
