It has been discussed before. It is a computer error.

+1. I had the exact same reading on my 06 Exige. Talked to the Regional tech rep for LotusCars USA, who in turn talked to the guys at Hethel. It is a known computer error, and I ultimately got documentation from LotusUSA indicating that the reading was an error and that my engine warranty was fully intact. Good to have with the documentation for the car if/when you sell it.
