What about this

It seems all faults refer to front left.
Take the wheel off and you will see the sensor behind the disc in the hub.
It’s a simple job to replace, I used Febi and they were around £20.
I did a video when the wife’s B200 had issues.
But the low ash levels mean the soot produced, and then burnt, was very little so this engine is running clean ?
There will always be carbon on valves and crowns as your oil will always be black 20 miles after an oil change.
I still think £3 worth of additive every tankfull will stop that.
But wouldn’t a low soot and ash level show it’s running very clean anyway ?
Doubt Millers will quiet down the agricultural tunes of a cold 651.
I’ve just bought some Mannol 9955 Diesel additive just for educational purposes, off on a 200 mile round trip this weekend so expecting good results...
How can you tell if it stops carbon build up better than regular fuel that meets British Standards already with additives ?
This is my DPF last time I checked it, I’ve never used additional additives.
I wonder how thrashing a car can clean the internals?
Surely just higher revs does nothing and once the car is up to temperature it can’t get any hotter to sufficiently burn off carbon .
I think these diesel additives are a bit like ladies wrinkle cream, most who use them swear by them, but they are very subjective.
Does normal Diesel not contain lubricants and detergents ?
I've previously used Millers and Redex, never noticed any difference, but not used it on this latest Merc...
The wheel sensors are easy and cheap to replace, or it could be a reluctor ring/bearing.
As said you would need to have something like the iCarsoft MB2 to diagnose properly, but if it is that, it's a cheap fix.
Lots of videos on YouTube.
When mine went I had steering but it was heavier, still power assisted. Lost ABS and TC as well, turned out to be magnetic wheel bearing that generates the ABS pulses, not the sensor itself.
If possible swap the sensors to see if the fault stays on the same axle.

Had same issue with mine, Aircap not moving and no light in button. The problem was that during an earlier Software update of the car, they forgot to "tell the system" that the car was equippped with Aircap, witch is optional. Hence the function...
