VelSatis EGR Valve Issue

Whoa, sounds rough! I had similar symptoms with my old Opel Astra, a real nightmare. Check engine light, smoke... the works! Is it affecting your emissions? Mine failed the emissions test miserably, and that's how I figured it out.

Interesting! I fear it will affect emissions! How did you confirm it was the EGR valve? I don't want to just throw money at it, but it really does feel like a vacuum leak somewhere.

Well, with my Astra, the garage diagnosed it pretty quickly once I told them about the emissions fail and the other issues. I'd say, get it checked out by a workshop. They'll hook it up to a diagnostic tool and know for sure. Save yourself the headache!

Thanks for sharing your experience! I appreciate the advice. I brought it to the shop, and you were spot on – the EGR valve was indeed defective. 355€ later, she's running smoothly again!
