Sprinter ABS and Traction Control Problems

My 2009 Mercedes Sprinter with a gasoline engine has an ABS light that keeps coming on, and I'm also experiencing traction problems. It feels like the ABS system is failing intermittently, mostly after driving for a while, especially on longer trips. The odometer reads 213414 km. A quick diagnostic points to a speed signal fault, possibly the ABS control unit. Has anyone else had similar issues? I'm trying to figure out if it's worth trying to fix myself or if I should just take it to a workshop. I've read that a defective ECM can cause these kinds of problems, but I'm not sure where to start looking. The estimated repair cost is around 1000€.

I have encountered similar ABS and traction control issues on my Sprinter. The speed signal fault you describe aligns with my experience. It is likely a defective control unit.

Thanks for the reply. Could you give me a bit more detail about the issue you had? Was it definitely the ABS control unit, and did you try any troubleshooting steps before replacing it? Any info would be helpful.

The diagnostic indicated a fault within the ABS module itself. Given the potential complexity and safety implications of the ABS system, I recommend professional diagnosis and repair.

Thanks for the advice. I decided to take it to a workshop. They confirmed it was the ABS control unit and replaced it. Everything seems to be working fine now, and the lights on the dashboard are gone.
