Seat Altea engine light and stalling issue
Summary of the thread
A 2010 Seat Altea with a gasoline engine is experiencing a check engine light and stalling at idle, with an error indicating incorrect fuel composition. The initial suspicion was a bad cable or plug. The issue was identified as a faulty connector on the fuel composition sensor, which was resolved by repairing the connection, costing 95€.

Fuel composition sensor location? And yes, there's a slight engine knock sometimes, especially when it stalls.

That's what I had. The location varies, but it's inline with the fuel line. I'd take it to a workshop. Saved me a lot of trouble.

It was a faulty connector on the fuel composition sensor. 95€ fixed it. Thanks for the tip!

Sounds like what happened with my Altea. Check the fuel composition sensor, could be a bad connection. Does the engine knock?
