Seat Inca check engine light and power loss
Summary of the thread
A 2001 Seat Inca is experiencing issues with the check engine light, stalling at idle, and reduced engine power. The suspected cause is a defective high-pressure pump and fuel volume regulator, potentially affecting the fuel injection system. A similar case involved a faulty fuel pressure regulator sensor, which can disrupt the air-fuel ratio. It is recommended to have the vehicle diagnosed by a professional to accurately identify and resolve the issue.

Interesting. When you say 'sensor related to the fuel supply', do you remember which one specifically? And did you also experience engine misfire at any point?

Yep, exact same symptoms – check engine light, rough idling, the works. It turned out to be the fuel pressure regulator sensor. If that's gone bad, it can mess with the fuel injection and cause all sorts of problems with air fuel ratio. Honestly, I'd suggest getting it checked by a workshop with proper diagnostic tools. Saved me a lot of time and headache!

It was the fuel volume regulator as I thought. The high pressure pump was defective, so I had it replaced. It cost 1510€ total. Thanks for the help.

Sounds familiar! I had similar check engine issues, stalling and power loss with my Inca. Have you checked the fuel injection system? For me it was a faulty car sensor related to the fuel supply. Could be the culprit causing rough idling. Might be worth a look!
