R230 SL500; previously 280CE and 180E.
The fill hole is closest to the front of the car and closest to the left fender. It requires a little pressure to get fluid in. I use a 10 ml plastic syringe with a thin plastic tube over the syringe nozzle and a rubber/plastic plug from a brake wheel cylinder fitted tightly over the plastic tube. (I drilled a hole through the plug first.) This fits snugly into the fill hole and allows hydraulic fluid to be forced into the pump reservoir. I have seen where others use a syringe with needle to get fluid into the reservoir. It takes a few refills of the syringe to fill the reservoir.

The plug I drilled a hole through was the rubber/plastic plug from a brake wheel cylinder, NOT the alloy plug that screws into the reservoir opening! Any similar plug will do, so long as it fits snugly into the reservoir fill hole and over the plastic tube.
