When I topped up t'other half's tank today she went to set the trip to zero but we couldn't find any means of doing so. I'm presuming that there should be a reset knob that fits through the hole in the left of the speedo' unit, if so ours is missing. Is it just a matter of locating one and sliding into place or is there likely to be some other problem, or have I just failed to see it?
Many thanks in advance, John.
