I bought an approved used car in 2015, is it fair that I now have to pay £400 for a waterpump replacement?

I own a 2011 Mercedes-Benz C-Class, which was bought in June 2015 as an approved used car from Mercedes Bristol with 68,000 miles on the clock. The car has been dealer maintained since new, except for one service in 2016. The car has now done 125,000 miles. A leaking water pump was recently diagnosed by my local Mercedes-Benz dealer in Cheshire, which they've quoted a total price of £408 to replace. Neither the dealer nor Mercedes-Benz UK are willing to offer any contribution towards the cost of replacing the pump, despite my claim that the wear and tear on this item is potentially beyond the control of the driver. Mercedes-Benz claim that the age and mileage of the car prevents them from making any contribution towards costs. Are Mercedes being unreasonable here?

The car has done 125,000 miles. You are being asked a reasonable £408 for a replacement water pump. I don't think you have any basis for a legal claim. In this case I actually agree with Mercedes-Benz that to expect a significant contribution from the company is not reasonable.
