There is some truth to this in my experience. A 240d owner phoned me and complained of having a top end of fifty miles an hour. When I eventually saw the car it had an electric fuel pump that was probably the issue. The lift pump was bad and they had substituted the electric pump. I suggested he repair the lift pump before doing much else.
Never knew what he did. Probably thought the old guy was crazy.
