VW Polo ABS Warning + Heavy Steering Points to Danger

As a 2015 VW Golf TDI owner, I experienced similar symptoms last season. The combination of ABS warning, steering issues and tire pressure alerts typically points to a faulty tire pressure monitoring system valve, which can trigger multiple warning systems. The tire monitoring sensor in one wheel was sending incorrect signals, causing the ABS system to engage unnecessarily. A proper diagnosis revealed air leak around the valve stem where the pressure sensor connects. This created pressure loss that was gradual but consistent. When this happened, the first sign was a flat tire warning, followed by ABS warnings as the system detected irregular wheel speeds. The heavy steering feel occurred because the ABS system was partially engaging due to false readings. The fix required replacing the complete valve stem assembly with an integrated TPMS sensor. While not a serious mechanical issue affecting core vehicle systems, it needed immediate attention to prevent potential tire damage and ensure proper ABS function. Before garage visit, check if: All tires maintain correct pressure for 24 hours, Visible damage around valve stems, Consistent steering feel when driving straight, ABS warning appears at specific speeds Getting this diagnosed early prevents more severe tire wear and keeps safety systems functioning properly.

Thanks for the detailed response. Your experience sounds exactly like what I am dealing with. Quick question, can you remember roughly how much the valve stem assembly replacement cost you? Also, has everything been working fine since the repair, or have you noticed any other issues? I want to budget properly and make sure this fixes the root cause before heading to the shop. My VW Polo has been sitting in the driveway since the tire pressure warning first appeared, as I did not want to risk damaging the tire sensor or making things worse. Will get it checked out based on your advice about the valve stems, sounds like that might be where my air leak is coming from.

Had the exact same valve stem issue fixed last week, problem solved completely. The repair cost was 280€ for replacing the defective tire pressure monitoring valve assembly. Since the fix, the low tire pressure warning disappeared and has not returned. The steering now feels normal with no vibration, and the ABS warning light cleared up immediately after the repair. Worth noting that catching it early prevented any uneven tire wear or damage to the pressure sensor system. You made the right call parking it until getting it checked. Continuous pressure loss through a faulty valve can strain the tire sensor and create incorrect readings in the whole monitoring system. With the new valve stem assembly, the tire maintains proper inflation and all warning systems are working as they should. The fix was straightforward and the whole monitoring system is back to normal operation. No other issues have come up since the repair was done.

Thanks for the helpful advice. Just got back from the mechanic and wanted to share my experience. The valve stem assembly replacement was exactly what I needed, total cost came to 295€ including labor. The mechanic found significant air leak around the old valve stem and confirmed the faulty pressure sensor was triggering both the tire pressure warning and ABS alerts. Got it fixed in under 2 hours. Took it for a test drive right after, steering feels smooth again with no vibration. All warning lights are off and the tire gauge shows stable pressure readings. Really glad I caught this before any serious tire damage occurred. Best part is I wont need to keep refilling that leaking tire every few days. The whole tire pressure monitoring system is working perfectly now. Definitely worth getting it sorted quickly rather than risking bigger problems down the road.
