How do you change the rear coil springs on Mercedes e270 cdi 2002?

To change the rear coil springs on a 2002 Mercedes E270 CDI, first, safely lift the vehicle and support it on jack stands. Remove the rear wheels, then unbolt the shock absorbers and lower control arms to allow for enough space to access the springs. Use a spring compressor to safely compress the old springs before removing them, then install the new springs and reassemble the components in reverse order. Ensure everything is tightened to the manufacturer's specifications and double-check alignment.
