Mercedes has revealed that a 'foreign substance' contaminated Nico Rosberg's Mercedes prior to the Singapore Grand Prix, which ultimately led to his retirement.

Rosberg retired at Marina Bay due to a steering wheel column loom failure and Mercedes has now revealed that the contamination occurred prior to the Singapore Grand Prix weekend, but did not manifest itself until the German attempted to leave the pits prior to the race.

'Forensic analysis has revealed that the steering column electronic circuits were contaminated with a foreign substance', said Mercedes.

'This occurred during our normal pre-event servicing procedures at the factory and the substance found is used as part of our standard servicing procedure.

'The relevant design has been in use since 2008 (6 seasons) without experiencing any fault. The contamination was not visible and did not manifest itself until Sunday as Nico went to the grid, although the steering column was used throughout the weekend and the car fired up as normal on Sunday morning.

'The result was an intermittent short circuit in these circuits. As a consequence Nico could not command the clutch nor change engine settings. The car was ultimately retired because it was unsafe to execute a pit stop without command of the clutch.

'Fresh parts will be used at the forthcoming races. The team has been working intensively on reliability and quality processes during 2013 and 2014 in order to improve our performance in this area and these efforts will continue at the same intensive level over the coming months.'
