Hyundai ix20 VANOS Fault

My 2011 Hyundai ix20, diesel engine, with 157802 km is throwing a check engine light and fuel consumption has increased. Scanned the codes, and it points to the inlet VANOS mechanics being faulty. Could be a defect in one of the camshaft solenoid valves – maybe a dodgy connection starving it of power? I'm thinking of checking the wiring harness first, but has anyone wrestled with this before?

A 2011 Hyundai ix20 is experiencing a check engine light and increased fuel consumption, with diagnostic codes indicating a potential fault in the inlet VANOS mechanics. The issue may stem from a defect in the camshaft solenoid valves or a poor electrical connection. Initial steps include checking the wiring harness, but the problem is likely related to the VANOS solenoid, which is a common issue. It is recommended to have a professional mechanic diagnose and potentially replace the solenoid to resolve the problem.

VANOS issues, huh? I had something similar with my ix20. Check engine light and the fuel economy went down the drain. VANOS is basically variable valve timing; it adjusts when your engine valves open and close for better performance and efficiency. When it goes wrong, it throws everything off. First question: Does the engine sound rough at all, especially at idle? And have you noticed any loss of power?

Good shout on the rough idle, hadn't really focused on that. Now that you mention it, yes, it's not as smooth as it used to be, a bit 'lumpy' if you will. Power loss is subtle but yeah, feels like it’s not pulling as strongly as it should. What exactly went wrong with yours? Was it the VANOS solenoid itself or something else?

Sounds very familiar. With mine it was indeed the VANOS solenoid. I spent ages trying to diagnose it myself, but in the end, I just took it to a local shop. They confirmed it was the solenoid. Honestly, unless you've got the right diagnostic gear, you might be chasing shadows. Could also be timing chain related, but the solenoid is the most common culprit. Best get it checked out by a pro.

Thanks for sharing your experience! I think you're right; I’ll book it in with a local mechanic. Diagnosis points towards the VANOS solenoid and repair bill should be around 250€. Hopefully, that'll sort it out and bring the old girl back to her former glory.
