Questions about this item

Does the electronic air strut use the factory air-line and electrical connector on 2007-2013 Mercedes-Benz S-Class models?

Yes, the assembly is built to match the original air-line and electrical connector for direct fitment on listed S-Class and CL-Class vehicles.

What clearance does the rear left strut need inside the wheel arch of a 2008-2012 S63 AMG?

The unit matches OE dimensions so it fits the standard rear left wheel-well space without modification on all listed models except 4Matic.

How is the electronic air strut installed and what step is often missed?

Mount the strut to the factory upper and lower points, reconnect the air line and electrical plug, then calibrate the suspension height with a compatible scan tool — skipping calibration triggers fault codes.
