Seat Leon Hybrid Issues Tire Pressure ABS and Steering

Whoa, that sounds eerily familiar! I had almost the exact same thing happen with my Leon. My tire pressure kept dropping, triggering the warning, and then the steering started acting up. It felt like wrestling a bear just to turn the wheel! I'd check your tire gauge and see if the pressure loss is consistent and quick. Is it always the same tire that's losing pressure?

Quick pressure loss is definitely the case! It's like I fill it up, and the next day BAM, warning light. Makes me think air leak. You mentioned a similar experience... did yours also involve the ABS lamp going crazy and the steering getting super heavy? Was it just a slow leak, or something more dramatic?

Yep, that's exactly what happened to me! The ABS light, the heavy steering, the whole nine yards. It's like a domino effect. The tire monitoring system freaks out because of the pressure loss, which then messes with the ABS and power steering. In my case, it was a faulty valve causing a slow air leak. Get it checked out at a workshop, and tell them to pay attention to the valve!

Took your advice and got the car to my local garage. Turns out it was, as you suspected, a faulty valve in the tire. They replaced it, checked all the other tires, and recalibrated the tire monitoring system. All in, cost me about 280€. Steering is back to normal, no more scary vibrations, and the ABS light is gone. Thanks a million for your help!
