Peugeot Boxer VANOS Solenoid Fault
Summary of the thread
A 2020 Peugeot Boxer diesel with 210,302 km is experiencing a check engine light and increased fuel consumption, diagnosed as a fault in the inlet VANOS. The issue could stem from a defective camshaft solenoid valve or a power supply problem. A similar case confirmed the VANOS solenoid valve as the culprit, leading to a recommendation to have it professionally repaired. The problem was resolved by replacing the faulty valve at a workshop.

Thanks for the reply! Power does seem a bit reduced. Interesting you had the same issue. If you don't mind me asking, what exactly was the problem with yours? Also, did it throw any other codes besides the check engine light? Starting to think it's connected with the inlet camshaft...

With mine, it turned out to be the VANOS solenoid valve, exactly what you suspected. I was hoping it was something easy like that, but honestly I'm no mechanic. You could try fiddling with it yourself, but in the end, I bit the bullet and took it to a proper workshop. Saved myself a load of frustration, and a bigger bill later! I'd recommend you do the same

Thanks for your advice. After a bit more research and your experience, I decided to take it to a workshop as you suggested. Turns out it was indeed the inlet camshaft VANOS solenoid valve. Repair cost me around 250€ to replace the faulty valve and reset the error codes. Appreciate the help!

Your Peugeot Boxer sounds like it's playing up like mine did a few months back! Similar symptoms – check engine light and the fuel economy went through the floor! I was pulling my hair out trying to figure out what was going on. Was yours also feeling a bit down on power? I was starting to wonder if I should check the injectors!
