ix35 Diesel Fuel Injection Issue

I'm having trouble with my 2013 Hyundai ix35 diesel. It's done about 76000 km. I'm seeing higher fuel consumption, less power, and it sometimes stalls. Plus, there's smoke from the exhaust when I accelerate. I checked for fuel leaks but found none. Could a bad cable or plug be the problem?

A 2013 Hyundai ix35 diesel is experiencing higher fuel consumption, reduced power, stalling, and exhaust smoke during acceleration. The engine management light is on, and a recent fuel filter change did not resolve the issue. A diagnostic scan at a workshop identified a faulty connection in the fuel injection system, which was fixed by replacing a cable and plug.

Did this summary help you solve your problem?

Those symptoms do point towards fuel injection problems. Is the engine management light on? Also, when did you last change the fuel filter? A clogged filter can cause similar issues.

Thanks. Yes, the engine light is on. The fuel filter was changed about 15000 km ago during a service. Could a bad sensor in the injection system cause this?

A defective sensor is possible, given the engine light and symptoms. But it's hard to know for sure without the right tools. I'd recommend a workshop does a diagnostic scan to find the problem. It'll save time and prevent further issues.

Thanks for the advice. I took it to a workshop, and the diagnostic scan found a faulty connection in the injection system, like I thought. Replacing the cable and plug cost 95€.
