Captur ABS TPMS and Steering Issues

Renault Captur, 2022 hybrid. Low tire pressure warning. ABS lamp is on, steering wheel vibrates, increased steering effort. TPMS reports low pressure, but visually tire looks fine. Could it be a defective valve causing a slow air leak and screwing with the sensor?

That sounds concerning. ABS light combined with steering issues and low pressure suggests a serious problem. Is the pressure consistently low, or does it fluctuate? Have you checked the pressure manually with a tire gauge to confirm the sensor reading? Ignoring this could be risky.

Pressure drops slowly over a few days. Gauge matches the TPMS reading. Wouldn't a faulty TPMS sensor throw a different error code?

A faulty sensor can throw odd codes, but consistent pressure loss matching both the TPMS and a manual gauge does lean toward a physical leak as you suggested. The steering issues and ABS light might be related to the pressure imbalance affecting the car's stability systems. To be absolutely sure, a workshop can diagnose the TPMS and air leak issue reliably.

Thanks. Turns out you were spot on – defective tire valve was the culprit. Air leak messed up the TPMS reading, which then impacted the ABS and power steering. Valve replacement and TPMS recalibration cost 280€.
