I am so gratefull for everyone posting this information. My Rover 75 2.5 2003 has exactly the same fault. It started four weeks ago. Every now and again it just turns over and over and over. I disconnected the battery thinking it was a computer fault. Once my computer average speed bit etc went wobbly and it fixed that. I think it was co-incidence that after a period of time it finally starts. The only thing I find of releif at the moment is that everyone says it eventually starts...other than this and a back door that wont open its a fantastic car and a joy to drive!! Anyone got any more advice than just change the two sensors?
