Would Mercedes-Benz contribute to an ABC pump replacement?

My 2010 Mercedes-Benz CL500 was making noise so I took it to local dealer. He called in a Mercedes-Benz dealer who diagnosed the ABC pump failing. The Mercedes-Benz dealer replaced the pump because the local garage asked them to. The total cost was £2,200, so I asked them to ask Mercedes-Benz to contribute. They are refusing. Is it likely Mercedes-Benz would because the car has done 38,000 miles with a full service history.
I don't think there's much chance of this because the car is more than 6 years old.
