Fiat Marea check engine light and stalling

Hi, I have a 2007 Fiat Marea with a gasoline engine. Recently, the check engine light came on, and the engine stalls at idle sometimes. Also, the engine power seems reduced. I've checked the fuel cap, but that's all. Any ideas?

A 2007 Fiat Marea is experiencing a check engine light, stalling at idle, and reduced engine power. The initial suggestion is a potential issue with the fuel volume regulator, which affects the fuel-air mixture. The recommended solution is to have the vehicle diagnosed by a professional workshop, which confirmed a defective fuel volume regulator and high pressure pump as the cause.

That sounds familiar! I had a similar issue with my Marea. The check engine light, stalling, and loss of power... It could be the fuel volume regulator. When that goes bad, it messes with the fuel-air mixture the engine needs, especially at lower speeds. Have you noticed any change in your fuel economy?

Fuel volume regulator, huh? Where is that located, and is it easy to check? I have not checked the fuel economy, but it feels like I'm visiting the gas station more often. Is this a complicated fix?

The fuel volume regulator is usually attached to the high pressure fuel pump. Honestly, it's not a simple check unless you have the right tools and know-how. Given the symptoms, especially the reduced power and stalling, and the likely expensive repair cost of a defective high pressure pump, I'd suggest taking it to a trusted workshop to get it properly diagnosed. Could save you money in the long run.

Thanks for the advice! I took it to a workshop, and they confirmed it was a defective fuel volume regulator, likely due to a defective high pressure pump. Repair cost is 1510€. Appreciate the help diagnosing the problem!
