Hello, any help is much appreciated, Thank you
Had a problem with YAW rate sensor so I turned dyno mode on until I found a part
on first position of the key I hold down reset button for 15s and in that menu I turn dyno mode on it automatically displays 3 faults ESP,BAS and ABS
witch usually disappears after I turn off dyno mode but after changing the YAW rate sensor the faults wont go away and ESP button doesn't work(usually doesn't when dyno mode is on)
I tried turning on dyno mode again and off, disconnecting battery, turning wheel full to the right and left than center, diagnostics cant read those faults,
recently had MB mechanic tell me that 'Road Test is active' witch is turned off performing a maneuver (picture best explains it) but it cant be done because ESP button doesn't work...

Try disconnecting the replacement ESP sensor and see what happens. I had a non-functional one in my car for years, and all it resulted in
was an ESP error. The sensor from Mercedes was like $700 but eventually I got one on Ebay for $40 and bam, problem solved, but yes, matching part number
or correct superceded part number as provided by a Mercedes dealer..
I had to get my sensor from Germany and yes its the exact same one, same part number, I will try disconnecting the sensor
any more suggestions, I thought I had to restart my car software somehow, is there an option for that with diagnostics?

No, you don't have to do any coding to change the Yaw sensor.
It was my mechanic who actually told me which one was bad and
that yes, pop a new one in from Ebay and be done with it.
Its in the trunk or thereabouts under the plastic panels in trunk of C coupe.
Plug and play. Turn the wheel lock to lock 3 times and be done wth it, if it's working correctly.
