2003 SL500 Service B
So took in the new to us SL in for service B . Now It Would crank awhile before (10 seconds )starting but once started runs like a dog no problems. Was told this could be from clogged fuel filter which gets changed on B service. Now I hear what I think is the fuel pump loud hum from the rear moving sitting still and the same long crank. Fuel pump weak?
