E-tron Steering Issues Signal Sensor Malfunction

Having experienced similar symptoms on my 2020 Audi e-tron GT, I can confirm this likely relates to the steering angle sensor. When my vehicle showed these symptoms, the traction control system was affected even before warning lights appeared. The steering angle sensor plays a crucial role in electronic stability control and requires precise calibration. In my case, the heavy steering and vibration stemmed from the sensor sending incorrect data to the power steering system. The wheel alignment also appeared off as a direct result. The repair involved: Complete diagnostic scan of steering sensors, Recalibration of the steering angle sensor, System reset of the electronic stability control, Verification of wheel alignment settings While not immediately dangerous, this issue needs attention soon as it can affect multiple safety systems. The sensor failure eventually impacts traction control and stability management if left unchecked. A certified shop with proper diagnostic equipment should handle this, as generic scan tools often miss the specific calibration requirements for electric vehicles. The repair itself was straightforward once properly diagnosed, taking about 3 hours to complete. The symptoms match exactly what you describe, suggesting your Q4 likely has the same sensor calibration issue my e-tron GT experienced.

Thanks for sharing that experience. Having dealt with nearly identical steering issues on my Q4 e-tron last month, I appreciate your detailed breakdown. The steering column symptoms you described match what I encountered perfectly. Did the repair cost include a full sensor replacement or just recalibration? My steering angle sensor needed complete replacement along with recalibration to resolve the alignment problems. Also curious if youve had any recurring issues since the fix?

Good news to report on the repair cost front. In my case, no full sensor replacement was needed, the issue was resolved through recalibration and coding of the faulty steering angle sensor, which came to 195 Euro. The alignment problems and heavy steering completely cleared up after the fix. The sensor failure was diagnosed during a thorough electronic scan, and proper coding resolved the traction control and steering response issues. Its been running perfectly for the past 6 months without any recurring problems. A proper diagnosis made all the difference, turns out the steering sensor only needed recalibration rather than replacement. This saved significant costs compared to a full sensor swap. The electronic stability system has worked flawlessly since the repair, with no more alignment problems or steering vibrations. If your replacement sensor was properly calibrated during installation, you shouldnt experience any further issues. The steering angle sensor is quite reliable once correctly set up and coded to the vehicle systems.

Thank you all for the input. I wanted to share how my repair experience went. After visiting a certified EV shop last month, they diagnosed the faulty steering angle sensor through their diagnostic equipment. The total repair included a complete sensor replacement plus recalibration, costing 580 Euro. The mechanic showed me how the old sensor was sending incorrect signals, affecting both the traction control and power steering systems. The alignment problems were definitely connected to the failing sensor. The full repair took about 4 hours, including thorough testing of all electronic stability functions. The steering feels perfect now, no more heaviness or vibrations. The mechanic was able to show me the before and after readings from the steering sensor, confirming the fix. Been driving for about 3 weeks since the repair with zero issues. The alignment is spot-on and all electronic systems are working as they should. Really glad I got this fixed before any major problems developed. The peace of mind was worth the investment.
