Front Level Went Down
Good Day Everyone,
Just replaced the front upper control arms for my W221, the car front went down and the vehicle is grounded almost 3cm (both sides) !! While the back is still ok as before, and vehicle rise button works fine too.
No errors, I checked the compressor and I made a quick check but it's showing everything is ok !!
Any idea what's the reason behind that ???
Is it ok to raise it using MB Start or DAS software or it's not recommended ???

I had a similar problem when I removed and replaced my front passenger Upper Control Arm.
That corner was about an inch lower, and had a terrible pull to the right.
The problem was - it is very easy to incorrectly mount the height sensor.
It took me a while to figure it out.
The sensor bracket is attached to the car with one of the upper control arm bolts.
But there is a tab on the bracket that needs to be located in the square hole.
If the tab is outside the hole... the suspension is lowered about an inch.
These pictures are my drivers side...
Here's what you normally see:
But if you look a little closer, you can see the square hole and tab:
