Peugeot Expert ABS and Steering Issues

I'm having a weird issue with my 2001 Peugeot Expert, gasoline engine. The tire pressure low warning keeps popping up, which I thought was just a slow leak at first. However, the ABS lamp lights up at the same time and the steering wheel vibrates. It feels like I need to put more effort into steering, almost as if the power steering has failed. I checked the tire pressures with my tire gauge and they seem okay, although one is a bit lower than the others. Could it be a faulty tire sensor or something more serious?

Summary of the thread

A 2001 Peugeot Expert is experiencing issues with a tire pressure warning, ABS light activation, and steering wheel vibration, suggesting a potential power steering failure. The tire pressure discrepancy was initially suspected to be a slow leak, possibly due to a defective valve. However, the combination of ABS and steering issues indicates a possible problem with the wheel speed sensor or ABS system. It is recommended to have the vehicle inspected at a workshop to diagnose and resolve the interconnected issues.

That's quite a combination of symptoms. When you say 'a bit lower', how much lower is the tire pressure compared to the others? Have you checked the tire itself carefully for any signs of damage, like a nail or a cut? It could still be a slow puncture even if it looks alright at first glance.

The tire is maybe 0.3 bar lower than the others. I did check for punctures, but I didn't see anything obvious. If it's not a simple puncture and the sensor's working, could a defective valve in the tire cause all these issues?

A defective valve causing a slow leak is plausible, especially in an older vehicle. However, the ABS and power steering issues suggest a potential link to a wheel speed sensor or the ABS system itself. Given everything, I'd recommend getting it checked at a workshop. They can properly diagnose the source of the warning lights and how it relates to the tire pressure issue.

I appreciate the advice. I'll take it to a workshop. You were spot on. Turns out that the tire pressure issue was indeed a defective valve in the tire and the cost for repair was 280€. I'll get that sorted and hopefully, the other systems will behave.
