ABC..down at one corner.
 

My car sits down at the right front corner.

No matter what the setting the front sits low. When I press the height button it rises as the others do etc...but it is still lower than it should be.

My MB specialist had it for a day, I though to simply calibrate the system and level things up...but he says it will not level up, and therefore there must be a faulty sensor within that strut.

Does this sound plausible?

Thanks in advance...this being my first post in this sub forum.

The vertical acceleration sensors are not the problem here. Sounds like your tech is on the right track looking at the strut first.

How is the suspension calibrated? I have the same problem, except with my Driver's rear. It goes up and down as normal, but remains between 1/2" and 3/4" lower than the rest. I took the tire off and saw no visible signs of leakage from the ABC system, nor does it seem to lose height overnight.

Is the ground flat and level? ABC does funny things when you park.
