I've done some searching and reading, but nothing quite related to what my car is doing.

Just had a bunch of suspension work done (Euro springs FTW), and they noticed that when turning right, about ~30mph, or even sitting still and turning full right, that the ABS pump starts going crazy.

They hooked up their computer, and found readings that when this happened, the speed sensor was detecting one of the wheels going something like 5K rpm, while the other was not, or slower (if moving).

Now, there's NO warning lights on the dash, no BAS/ESP, nothing. They only noted it when they were scanning for codes.

I've read about issues with the steering angle sensor on the column, but wondering if I should start there or a ABS speed sensor? I still have yet to try the 5 times lock to lock to reset the sensor, but if that doesn't fix it, where would you recommend starting?

Logic dictates that the ABS pump reacts to a sensor reading, so that would be the logical place to start.

Any help appreciated, thank you!!

Sounds like the ABS Sensor is the fault. I have seen ABS modules give this sort off issue on BMW's but not on a MB. The sensor is cheap so I'd just replace it and see how it goes from there.

I need to replace my ABS wheel speed sensor as well - any idea if OEM is Bosch or Beck/Arnley or does it matter?

Bosch w0133-1717018
Beck/Arnley 0844166

Thanks!

I doubt if it would be anything other than Bosch

Either will work but I'd prefer the Bosch.
