VW Beetle ABS Issue Points to Faulty G-Force Sensor

Having worked on cars for a few years, I faced almost identical issues with my 2013 VW Golf. The symptoms were exactly what you describe, persistent ABS light and system malfunction related to sensor readings. After running a diagnostic scan, my workshop found that the lateral sensor and yaw rate signals were inconsistent, which directly impacted vehicle stability control. Initially, they suspected just a sensor fault, but it turned out the control unit itself was defective and needed replacement. The complete repair involved: Full system diagnostic testing, Control unit replacement, Steering angle sensor recalibration, Final system verification Total cost was around 1000€, but it completely resolved the issue. The ABS and stability control systems have worked flawlessly since. To provide more specific guidance for your case, could you share: Have you noticed any stability control warnings? Does the issue occur more during tight turns? Have you had any recent suspension work done? What diagnostic trouble codes were shown in the scan? These details would help determine if your Beetle is experiencing the same root cause as my Golf did.

My Beetle has 82199km on the odometer now and I find your feedback very helpful. The electronic stability system warning light did actually come on during tight turns, which matches your experience. Vehicle stability seems most affected during low-speed cornering. The workshop ran a diagnostic scan last week showing error code G200, pointing to the lateral acceleration sensor. The traction control also cuts in unexpectedly sometimes, especially during normal driving conditions. I just had the 80000km service done last month, but no suspension work was included. I suspect I might be looking at a similar control unit replacement based on these matching symptoms.

Thanks for those additional details about your Beetle. The symptoms you describe align perfectly with what I experienced, especially the stability control activation during low-speed turns and the G200 error code. After dealing with this on my Golf, I learned that the lateral sensor issues often indicate a wider control unit problem. The unexpected traction control activation you mention is a classic sign that the yaw rate calculations are off, which affects the entire vehicle stability system. When my control unit was replaced, the workshop explained that the sensor and control unit work as an integrated system. They also performed a complete wheel alignment to ensure optimal electronic stability control function. Since you mention having the 80000km service recently, its worth noting that my issues started shortly after routine maintenance too. The timing suggests these problems typically emerge around this mileage point in VW models. Based on the matching error code and behavior, I suggest having them check: Control unit signal processing, Yaw rate sensor calibration, Complete stability system diagnostics Given the identical symptoms and error codes between our cars, preparing for a control unit replacement might be wise. The 1000€ repair cost I mentioned earlier should be similar for your Beetle.

Thank you for sharing your repair experience. The matching symptoms between your Golf repair case and my Beetle are quite telling. The stability control warnings during tight turns plus the G200 error code really point toward this being more than just a simple sensor issue. The traction control problems during normal driving conditions have been concerning me, so its good to know this fits the pattern you described. I will definitely have the workshop check the complete control unit and yaw rate calculations rather than just replacing the lateral sensor. Since my recent 80000km service didnt include any suspension work, I should probably get the wheel alignment checked too when they diagnose the control unit. Safety warning systems like ABS and stability control are too important to leave partially functioning. Knowing the repair cost was around 1000€ helps me budget properly for this fix. I will schedule the repair soon and make sure they perform all the steps you mentioned, especially the steering angle calibration after any component replacement. At least I now have a much clearer picture of what to expect at the workshop.
