E220 estate 2007/ Sl500 R129, 2000
The fleets been operating great, so not been on for a while.
New Problem - rear end suspension bottomed out on both sides and pump NOT running. I have looked at loads of previous Threads and done some trouble shooting. Will detail here, may help someone else. Not fixed yet though??

Work so far -
Checked fuse 32 under drivers carpet= ok.
Checked Relay K67 (I think,,, hard to find ) in engine bay fuse box, near firewall = ok
There seems to be some other light weight fuses involved. and think I have chked them (drivers door/dash end cover) = ok
Disconnected pump ( LH side under front valance) and jumped from a battery. pump runs = ok ( but not from car power)
I have taken a look at the level sensor ( RH front upper wishbone) but not checked for power= ?
My next step is to check the Control module. I have no idea where this is. Seems it might be part of a SAM. Can someone please tell me where to ,look on a 2007 E220 W211 Estate... HELP
Once I get the pump running, can see if some leaks etc caused a problem.

Just out of interest, problem seems to have started when I started the car and reversed slowly out of parking space over a speedbump... no shock or anything, slight bump!!
Any assistance really appreciated.
