Peugeot 308 VANOS Fault Fuel Consumption

Hey, I'm having a head-scratcher with my 2019 Peugeot 308 diesel. The check engine light keeps popping on, and I've noticed my fuel consumption has gone up. I scanned it and it's showing a fault with the inlet VANOS mechanics. Mileage is at 127507 km. Anyone else run into this? I suspect a dodgy camshaft solenoid valve or a power supply issue to it, but I'm open to suggestions before I start tearing things apart.

I had something similar with my 308. Noticed the engine felt a bit sluggish too? I'm no mechanic, but it sounds like it could be variable timing related. Was it throwing any other codes, like maybe indicating an engine misfire?

Thanks for the reply. Sluggish is a good way to describe it, yeah. No other codes are showing up, just the VANOS one. Did yours also have increased fuel consumption? Any idea what fixed it for you?

Yeah, the fuel consumption definitely took a hit. I was putting more fuel than usual. Honestly, I didn't mess with it myself. Took it straight to a workshop. They sorted it out pretty quick. Sounds like a similar problem.

Appreciate the insight! Sounds like I'm on the right track, but I'll probably take it to a shop as well. Just got the repair bill: 250€. Thanks again!
