VW Suran ABS Warning Light Won't Turn Off, Urgent Fix

I had a similar situation with my 2009 VW CrossFox last winter. The ABS and stability control warnings appeared suddenly during normal driving. The initial diagnostic revealed multiple stored codes related to wheel speed sensors and the ABS control module. The root cause turned out to be more complex than just a faulty sensor. The ABS control unit was defective, affecting both the traction control and electronic stability systems. These components work together using yaw rate sensors and wheel speed data to maintain vehicle stability. The repair required: Complete testing of all wheel speed sensors, Verification of the ABS hydraulic unit, Replacement of the defective control module, Full system calibration, Road testing to confirm proper safety warning signals This was a serious safety concern since it disabled multiple critical driving assistance features. Given the similar symptoms in your Spacefox, I suggest having the mechanic specifically check: 1. The integrity of all wheel sensor wiring 2. The ABS control module functionality 3. The communication between stability control components 4. A full wheel alignment to rule out any sensor misreadings The symptoms point toward a control unit issue rather than just a lateral sensor problem.

I faced that exact issue on my Spacefox. Thanks for the detailed response. The ABS warning kept coming on and the traction control was acting up. Following your advice, got the electronic control unit tested and replaced. The diagnostic scan showed similar error codes to what you mentioned. The lateral sensor readings were actually fine, it was indeed the main control module causing all the trouble. The yaw rate sensors started working properly after the replacement. Quick question, do you remember roughly how much the repair ended up costing? Also, has everything stayed working properly since the fix? Want to get an idea if I should expect any related issues popping up later.

Just wanted to follow up, since having the mechanic look at it based on the diagnostics, I can confirm the lateral acceleration sensor fault was completely resolved. The total repair cost came to 1000€ mainly for replacing the affected control unit that was defective. Everything has been working flawlessly for the past 8 months. The electronic stability system is functioning exactly as it should, with no warning lights or error codes reappearing. The vehicle stability is back to factory specifications, and the steering angle sensors are all reporting correct values. The diagnostic scan we ran last week showed zero stored fault codes, confirming the fix was successful. Based on my experience, once the control unit is properly replaced and calibrated, you shouldnt expect any related issues to pop up again. The investment was worth it considering how critical these safety systems are. The repair shop did a thorough job testing all connected components to ensure the whole system works together properly.

After getting all this helpful advice, I finally got my car fixed last week. The mechanic ran a complete diagnostic scan which confirmed the control module was faulty. I ended up paying 950€ for the full repair, including parts and labor. The shop went through all the connected systems, checking the yaw rate measurements and vehicle stability components. They found some wiring issues near the wheel sensors too, which they fixed while the car was up on the lift. The safety warning lights are now completely off and the ABS works perfectly. The electronic stability control kicked in properly when I hit a slick spot the other day, definitely feels safer now. Glad I pushed to have them do a thorough check rather than just replacing sensors out of nowhere. The repair was expensive but worth every cent for the peace of mind. Thanks again for pointing me in the right direction with this.
