Pics and info on lowering W211 E55
Good news for W211 E55 owners. The car CAN be lowered through the ECU. This is a factory adjustment performed by an authorised dealer (MB owned actually) so it does not effect warranty. There is no need for aftermarket modules etc and best of all, it is completely adjustable.
Anyone who would like specific details should email me.

I didn't actually do before and after measurements, however when I now raise the suspension (with it still in Sport II) the raised height doesn't seem much higher than what it was before, so the drop would be around 20mm, given the raised height is an increase of 25mm. (did that just make sense??).
It has not effected any of the Airmatic functionality in any way.
To return the car to stock ride height the car must be taken back to the dealer to reset the sensors.
Interestingly AMG do provide this as a service at the factory where it is referred to as "Ride Height Optimisation". I am sure that they too do this as a complimentary service for there customers...........

Sorry guys.
Since there appear to only be a few E55 owners on the board I thought it would be easiest to email the instructions, but given that I received around 20 email requests, I will post it here where I should have put them all along.
The car should firstly be driven on to the wheel alignment jig. This is to ensure that it is on a completely flat surface and plugged into the service computer.
Once plugged in, move to Airmatic adjustments.
In this menu option you can raise/lower each of the front wheels individually as well as the rear.
This also shows you the voltage reading of each of the three sensors, along with the tolerance range for each. The idea is to then adjust each to the appropriate reading for the ride height you wish to obtain. (higher voltage = lower) The biggest limitation is the rear as mine is set at the threshhold value of 3.0V, sensor is different, but the tolerance values are on the screen for you to see anyway.
The trick is to get the car to save the values, as once you go to save the changes to 'active" the system asks for a secondary set of inclinometer values. From memory we used 4,-1.3 (I'll double check this at the office today), but had to try three or four different values near the listed range limits to get the system to accept the ride height changes.
This change does not affect the functionality of the suspension in any way, you can still raise and lower the car from the console for example. I have had no rubbing problems which was my biggest concern and believe me, I've done plenty of testing!!
The car now turns in quicker and feels "smaller" on the road. This has also helped reduce lean through faster turns and has not negatively impacted the cars ride.
