Vezel engine stalling power loss

Alright Vezel gurus, I've got a head-scratcher. My 2021 Honda Vezel with a gasoline engine is acting up. It's got 222764 km on the clock. The check engine light is on, the engine sometimes stalls when idling, and it feels like I'm missing some serious power. Now, I'm thinking it might be the fuel volume regulator acting up, possibly due to a high pressure pump issue. Anyone else experienced this? What do you reckon?

Summary of the thread

A 2021 Honda Vezel with 222,764 km is experiencing engine stalling, power loss, and a check engine light. The suspected cause is a faulty fuel volume regulator, potentially due to a high-pressure fuel pump issue. The problem was confirmed by a workshop, which identified both the high-pressure fuel pump and the fuel volume regulator as defective, leading to a successful repair.

A Vezel with similar issues, you say? Funny you should mention that. I had almost identical symptoms on my Vezel, though I can't recall the mileage exactly. Did you notice any changes in fuel economy recently, alongside the rough idling and power loss? Because if so, it strengthens the probability that your high-pressure fuel pump is faulty.

Fuel economy... hmm, now that you mention it, I have been filling up more often. How sure are you about the high-pressure fuel pump? What did you do to fix it? Was it expensive?

Given the symptoms and the fuel economy drop, it does sound like the high-pressure fuel pump. Now, I'm no mechanic, but from what you've described and what I experienced, it's highly probable. I strongly suggest taking it to a reputable workshop for a proper diagnosis. They can confirm the fault and give you a quote for the repair.

Thanks for the insight! I took it to the shop, and you were spot on. They confirmed it was the high-pressure fuel pump and a defective fuel volume regulator. Cost me 1510€ to get it all sorted, but at least it's running smoothly again. Appreciate the help!
