Peugeot 406 ABS Power Steering Issue

I'm experiencing an issue with my 2004 Peugeot 406 diesel. I'm getting a low tire pressure warning, but that's not all. The ABS lamp lights up intermittently, the steering wheel vibrates, and it feels like the power steering is failing at times, requiring more effort to steer. I've checked the tire pressure manually with a tire gauge, and it seems fine. Could it be a faulty tire sensor?

Interesting. I had a similar issue on my 406. Tire pressure warning plus weird steering issues... Did you check the valve on the tire itself? It might be defective, leading to a slow pressure loss that your gauge isn't picking up immediately.

Thank you for the swift response. I haven't specifically checked the valve. Is a defective valve really capable of causing all these other symptoms – the ABS and power steering issues as well?

Well, the low tire pressure warning can mess with the ABS system, which in turn affects the power steering due to how the car's computer interprets the signals. If the valve is leaking, even slowly, it'll trigger the whole chain reaction. You could try tightening the valve core, but honestly, if it's old, I'd just get it replaced. Maybe best to visit a workshop.

Much appreciated. I followed your suggestion and took it to a workshop. Turns out, it was indeed a defective valve in one of the tires. Replaced all four for 280€ and the problem is solved. Thanks again for pointing me in the right direction!
