i30 Diesel Rail Pressure Sensor Issue

My 2013 Hyundai i30 diesel is showing signs of a bad rail pressure sensor signal. Check engine light is on sometimes, engine stalls when idling, and power is down. It's only got 41814 km on it. Has anyone else had this?

A 2013 Hyundai i30 diesel is experiencing issues with a bad rail pressure sensor signal, indicated by a check engine light, engine stalling when idling, and reduced power.

Hey, that sounds familiar. I had almost the exact same thing happen with my old Opel Astra, although the engine was petrol. Check engine light, stalling... the whole shebang. Was it the pressure sensor for sure?

In your case with the Opel Astra, was the faulty pressure sensor confirmed with diagnostic testing, or was it identified through a process of elimination? And was the behavior identical, or were there any subtle differences in the symptoms exhibited?

No problem! It was definitely the pressure sensor – the workshop guys ran diagnostics and that's what came up. Symptoms were pretty much identical to what you described. I'd get it checked out properly at a workshop if I were you.

Thanks for the confirmation and advice. I replaced the rail pressure sensor and that fixed it. Total cost was 240€.
