The Monte Carlo Rally running order is a mystery at the end of day one of the World Rally Championship season opener with a timing problem leaving teams and fans in the dark.
Sistemas Integrales de Telecomunicacion (SIT) took over from Stage One Technology as the WRC's timing and tracking supplier for 2013. An issue with communication on stage three meant a slew of unreliable times as the official system registered gaps of several minutes between lead cars.
Although accurate timings appear to be coming through from stage four, the last of Wednesday's leg, the overall order remains unknown given the lack of SS3 times.
Unofficial estimated times suggest Sebastien Loeb continues to lead the rally for Citroen, with an increasing gap over Volkswagen's Sebastien Ogier.
Thierry Neuville, who had been fifth at the end of the morning, has retired after sustaining damage to his Qatar M-Sport Ford on stage four.
The tracking system had also caused issues on the first loop, when Loeb's car was falsely registered as having stopped on stage one. The officials then asked Citroen to disconnect sensors in Loeb and Dani Sordo's cars.
"For safety reasons and after consultation with the FIA technical delegate, the stewards permit to disconnect the sensors of the GPS tracking system in car #1 and car #10, as this item apparently blocks the sending of signals from the GPS safety tracking system in these cars," said a stewards' statement.
