E220 SE ABS Fault & Traction Fault
I Have a 2015 E220 SE Bluetec Auto, with abs fault on front left, I have changed Wheel Bearing and ABS ring and also sensor but still have issues, the following fault codes come up
C04AE00 The signal from component 'L6/1 (Left front axle rpm sensor)' is faulty
U140900 An implausible left front wheel speed signal was recieved
U010100 Communication with Control unit 'Transmission' has a malfunction
U041600 Implausible data were recieved from control unit 'Traction Sytem'
U045A00 Implausible data was recieved from control unit 'Parking Sytem'
The last Three codes only clear on seconed attempt and once car reaches 20mph, all codes re apear.
559916 The battery of the tire pressure sensor has a malfunction. The limit value for electrical voltage has not been...
I presumed tyre pressure issue has nothing to do with this, tyre pressure still shows correct on dash
Any help or advice would be gratefully received, Thanks in advance.

Goood job with your fixing the ring and wheel sensor.
From here we can guess it may be something else causing this issue. It does seem like a few modules getting upset. It's only normal here for tranny to complain about missing wheel speed.
Can you have a look at ESP wheel speed data to confirm where info gets lost.

Today had another computer conected and following code was shown
C04AE00 The signal from component L6/1 (Left front axle sensor) is Faulty
On live data speed will go the same as other three wheels upto around 15-25mph then fault comes on and speed will show 40723mph and will stay like that until codes are cleared

almost fixed
All right... this fault seems pretty well defined as a bad ESP input.
Inspect ESP connector for crusties. Inspect harness for integrity all the way down to wheel. Scope Left vs. Right side wheel sensor input.
