Weird I would not have suspected the check engine light for that, but who knows. I just had it come on recently (without any messages) for what turned out to be a heat plug failure. Have you got the pump fixed? Its the sort of thing that will stop the car eventually if it thinks its not meeting emissions regs (at least for EU6 anyway).
