The warranty claim company has refused to pay for the replacement of the suspension pump on my Mercedes S class saying that the agreement covers for the 'actual breakage of a mechanical part' 'and as the pump still runs it is not actually broken, just worn out'. It was producing 4 bar of pressure, unable to raise the car to the appropiate ride level. I maintain that if the pump was not broken, it would not have needed to be replaced. It does/did not perform the function intended.

My reaction is to sue them, but I was wondering if anyone had a similar situation & their experience/advice.

Many thanks.
