Trafic Tire Pressure and ABS Issues

My 2009 Renault Trafic with a gasoline engine has a low tire pressure warning and intermittent ABS light. The steering wheel vibrates and is harder to turn, like the power steering is failing. I've done 218021 km. I suspect a valve issue causing a slow leak.

I had similar symptoms in my Trafic, but no ABS light. Check your tires for punctures. It could be a nail or screw causing a slow leak.

Thanks. I checked the tires and didn't see any punctures. Could the valve be leaking even without tire damage? Could a faulty tire sensor cause this?

Yes, a valve can leak even if the tire looks fine. The valve stem seals degrade. The power steering issue might be related if the ECU uses tire pressure sensors. A workshop is probably best.

Thanks for the confirmation. I took it to a workshop, and the valve was defective, causing a slow leak. The repair was 280€.
