The lamp to the right of the engine oil pressure warning lamp is the CC gearbox warning lamp. It indicates a failure in the gearbox, so not necessarily the F1 pump (though it may be). In my experience it can come on occasionally in heavy traffic (the software riding the clutch), but if you've lost reverse I would have clutch wear and PIS settings read as well as the F1 oil level. Do you hear the F1 pump priming when you unlock the car?
