I have a CLK 320 W209 from 2003. Got this BAS, ABS, ESP errors. I found only one error code pointing to problem with (right rear speed sensor C1134). The multipole ring seems in super condition. The right rear sensor seems in nice condition. But when i look at the speed rotation info it says that all sensors has a speed of 0.49 km/h standing still. And its stuck on this value for them all.
Anyone have any idea how what this could point to? Could it be the Anti-Lock Brake ABS Pump?
I haven't found any broken fuses either. And the battery is in pretty good condition.
The steering sensor position seem ok as well and the break sensor.
I haven't found the relay for the ABS pump so i haven't tested if it runs
I ordered a new sensor. I will write info here if it helps. Also hope i can give info later on on how this was solved to help someone else with similar problem.
Hello! Well the outcome was this: The sensor data was stuck on some bad value but when i did live logging the sensors from my reader started working with different speeds. It was then clear the rear right sensor was faulty.
So i changed it.
I must however say it wasn't so easy since i didn't find any info on changing this on the rear on CLK. It turns out the sensor goes back to the middle of the rear so i had to jack the hole thing up etc.
When trying to remove the old error codes it didn't work initially but on the second try it finally worked so now it works nice again.

How were you able to do the live logging with the reader? Close the hood and just hope the cord didn't pinch? I've got a W208 and the same reader you do and need some live data, but with where the port is positioned, I can't figure out how folks are doing it.
My reader only needs connecting to the odb port no other power src. so no problem in having it on when test driving inside the car. maybe you use your ODB reader in a wrong maner?
The sensor: i just reattached with it's bolt before doing this test. Since i had already removed it from its sensor "hole".

Not typical BAS ABS ESP Error
